- Abstract
Background: Species of the carnivorous family Lentibulariaceae exhibit the smallest genomes in flowering plants. We explored the hypothesis that their minute genomes result from the unique mitochondrial cytochrome c oxidase (COX) mutation. The mutation may boost mitochondrial efficiency, which is especially useful for suction-bladder traps of Utricularia, but also increase DNA-damaging reactive oxygen species, leading to genome shrinkage through deletion-biased DNA repair. We aimed to explore this mutation's impact on genome size, providing insights into genetic mutation roles in plant genome evolution under environmental pressures., Methods: We compiled and measured genome and mean chromosome sizes for 127 and 67 species, respectively, representing all three genera (Genlisea, Pinguicula, and Utricularia) of Lentibulariaceae. We also isolated and analyzed COX sequences to detect the mutation. Through phylogenetic regressions and Ornstein-Uhlenbeck models of trait evolution, we assessed the impact of the COX mutation on the genome and chromosome sizes across the family., Results: Our findings reveal significant correlations between the COX mutations and smaller genome and chromosome sizes. Specifically, species carrying the ancestral COX sequence exhibited larger genomes and chromosomes than those with the mutation. This evidence supports the notion that the COX mutation contributes to genome downsizing, with statistical analyses confirming a directional evolution towards smaller genomes in species harboring these mutations., Conclusions: Our study confirms that the COX mutation in Lentibulariaceae is associated with genome downsizing, likely driven by increased reactive oxygen species production and subsequent DNA damage requiring deletion-biased repair mechanisms. While boosting mitochondrial energy output, this genetic mutation compromises genome integrity and may potentially affect recombination rates, illustrating a complex trade-off between evolutionary advantages and disadvantages. Our results highlight the intricate processes by which genetic mutations and environmental pressures shape genome size evolution in carnivorous plants., (© The Author(s) 2024.

Telomeres are basic structures of eukaryote genomes. They distinguish natural chromosome ends from double-stranded breaks in DNA and protect chromosome ends from degradation or end-to-end fusion with other chromosomes. Telomere sequences are usually tandemly arranged minisatellites, typically following the formula (TxAyGz)n. Although they are well conserved across large groups of organisms, recent findings in plants imply that their diversity has been underestimated. Changes in telomeres are of enormous evolutionary importance as they can affect whole-genome stability. Even a small change in the telomere motif of each repeat unit represents an important interference in the system of sequence-specific telomere binding proteins. Here, we provide an overview of telomere sequences, considering the latest phylogenomic evolutionary framework of plants in the broad sense (Archaeplastida), in which new telomeric sequences have recently been found in diverse and economically important families such as Solanaceae and Amaryllidaceae. In the family Lentibulariaceae and in many groups of green algae, deviations from the typical plant telomeric sequence have also been detected recently. Ancestry and possible homoplasy in telomeric motifs, as well as extant gaps in knowledge are discussed. With the increasing availability of genomic approaches, it is likely that more telomeric diversity will be uncovered in the future. We also discuss basic methods used for telomere identification and we explain the implications of the recent discovery of plant telomerase RNA on further research about the role of telomerase in eukaryogenesis or on the molecular causes and consequences of telomere variability.

Premise Among the sophisticated trap types in carnivorous plants, the underground eel traps of corkskrew plants (Genlisea spp., Lentibulariaceae) are probably the least understood in terms of their functional principle. Here, we provide a detailed analysis of structural and hydraulic features of G. hispidula traps, contributing to the ongoing debate on whether these traps can actively generate water streams to promote prey capture. Methods Anatomical and hydraulic traits of detached traps, including inner trap diameters, chamber line element, hair length, glandular pattern, and hydraulic conductivity, were investigated quantitatively using light and electron microscopy, x‐ray microtomography, and hydraulic measurements. Results Hydraulic resistivity in the neck of the trap, from the trap mouth toward the vesicle (digestive chamber) was 10 times lower than in the opposite direction. The comparison of measured and theoretical flow rates suggests that the retrorse hairs inside trap necks also provide considerable resistance against movement of matter toward the vesicle. Hairs showed a gradient in length along the neck, with the shortest hairs near the vesicle. Co‐occurrence of quadrifid and bifid glands was limited to a small part of the neck, with quadrifids near the vesicle and bifids toward the trap mouth. Conclusions The combination of structural gradients with hydraulic anisotropy suggests the trap is a highly fine‐tuned system based on likely trade‐offs between efficient prey movement in the trap interior toward the vesicle, prey retention, and spatial digestion capacities and is not counter to the generation of water streams., publishedVersion

Subterraneous tubular rhizophylls (traps), with two helically twisted arms. Basifixed and free scales, bracts and bracteoles. Glabrous scape, scales, bracts, bracteoles, pedicels, sepals and capsule or covered with eglandular and/or long-stalked glandular trichomes. Ascending, recurved, abruptly recurved or strongly circinate pedicels in fruits. Calyx with 5 homomorphic sepals. Corolla with gibbous or non-gibbous palate, spur parallel to the pedicel or to the lower corolla lip. Bivalvate or circumscissile capsule. Comments:— The genus is divided into two clearly distinct subgenera, G. subgen. Genlisea, which is recognized by ascending pedicels in fruits, spur parallel to the lower corolla lip and circumscissile capsule, while G. subgen. Tayloria Fromm-Trinta (1977: 1) has recurved, abruptly recurved or strongly circinate pedicels in fruits, spur parallel to the pedicel and bivalvate capsules. Members of G. subgen. Tayloria are endemic to Brazil, and are purple/lilac flowered with the exception of G. lobata (white). Genlisea subgen. Genlisea is subdivided into three sections, of which two are African (G. sect. Africanae Fleischmann et al. (2010: 781) and G. sect. Recurvatae Fleischmann et al. (2010: 781) and one is Neotropical (G. sect. Genlisea). The Neotropical section is composed mainly by yellow flowered species with the exception of G. guianensis, G. multiflora Fleischmann & Costa (2017: 289) and G. sanariapoana Steyermark (1953: 534)., Published as part of Guedes, Felipe Martins, Miranda, Vitor Fernandes Oliveira & Alves, Marccus, 2022, Diversity and distribution of Lentibulariaceae in Bahia state, Brazil: implications for phytogeography and conservation, pp. 213-255 in Phytotaxa 556 (3) on page 226, DOI: 10.11646/phytotaxa.556.3.1, http://zenodo.org/record/6972832, {"references":["Fromm-Trinta, E.

In the genus Genlisea as well as in its sister genus Utricularia, the palate probably plays a key role in providing the colour, mechanical and olfactory stimuli to attract insect pollinators and to guide them to the generative structures and the nectary spur. However, information about the micro-morphology of the palate of Genlisea is scarce. This study aims to examine the structure of the palate in Genlisea hispidula in detail as well as the palate from other five species from the subgenus Genlisea. In particular, its aim is to ascertain whether these palates function as an area for the osmophores in the flower or whether they produce nectar. We showed that the palate in all of the species that were examined was the glandular type and that it had capitate, glandular trichomes, which had a similar general architecture across the species that were examined. No nectar secretion was observed on the palates. The ultrastructure of the palate trichomes showed that the palate glandular trichomes most probably function as scent glands that produce an olfactory stimulus for flower pollinators.

Genlisea margaretae, subgenus Genlisea, section Recurvatae (184 Mbp/1C), belongs to a plant genus with a 25-fold genome size difference and an extreme genome plasticity. Its 19 chromosome pairs could be distinguished individually by an approach combining optimized probe pooling and consecutive rounds of multicolor fluorescence in situ hybridization (mcFISH) with bacterial artificial chromosomes (BACs) selected for repeat-free inserts. Fifty-one BACs were assigned to 18 chromosome pairs. They provide a tool for future assignment of genomic sequence contigs to distinct chromosomes as well as for identification of homeologous chromosome regions in other species of the carnivorous Lentibulariaceae family, and potentially of chromosome rearrangements, in cases where more than one BAC per chromosome pair was identified.

The community of algae occurring in Genlisea traps and on the external traps surface in laboratory conditions were studied. A total of 29 taxa were found inside the traps, with abundant diatoms, green algae (Chlamydophyceae) and four morphotypes of chrysophytes stomatocysts. One morphotype is described as new for science. There are two ways of algae getting into Genlisea traps. The majority of those recorded inside the traps, are mobile; swimming freely by flagella or moving exuding mucilage like diatoms being ablate to colonize the traps themselves. Another possibility is transport of algae by invertebrates such as mites and crustaceans. In any case algae in the Genlisea traps come from the surrounding environment. Two dominant groups of algae (Chladymonas div. and diatoms) in the trap environment, show ability to hydrolyze phosphomonoseters. We suggest that algae in carnivorous plant traps can compete with plant (host) for organic phosphate (phosphomonoseters). From the spectrum and ecological requirements of algal species found in the traps, environment inside the traps seems to be acidic. However, further studies are needed to test the relations between algae and carnivorous plants both in laboratory conditions and in the natural environment. All the reported taxa are described briefly and documented with 74 LM and SEM micrographs.

The monophyletic carnivorous genus Genlisea (Lentibulariaceae) is characterized by a bi-directional genome size evolution resulting in a 25-fold difference in nuclear DNA content. This is one of the largest ranges found within a genus so far and makes Genlisea an interesting subject to study mechanisms of genome and karyotype evolution.G. nigrocaulis, with 86 Mbp one of the smallest plant genomes, and the 18-fold larger genome of G. hispidula (1550 Mbp) possess identical chromosome numbers (2n=40) but differ considerably in chromatin organization, nuclear and cell size. Interphase nuclei of G. nigrocaulis and of related species with small genomes, G. aurea (133 Mbp, 2n=104) and G. pygmaea (179 Mbp, 2n=80), are hallmarked by intensely DAPI-stained chromocenters, carrying typical heterochromatin-associated methylation marks (5-methylcytosine, H3K9me2), while in G. hispidula and surprisingly also in the small genome of G. margaretae (184 Mbp, 2=38) the heterochromatin marks are more evenly distributed. Probes of tandem repetitive sequences together with rDNA allow the unequivocal discrimination of 13 out of 20 chromosome pairs of G. hispidula. One of the repetitive sequences labeled half of the chromosome set almost homogenously supporting an allopolyploid status of G. hispidula and its close relative G. subglabra (1622 Mbp, 2n=40). In G. nigrocaulis eleven chromosome pairs could be individualized using a combination of rDNA and unique genomic probes. The presented data provide a basis for future studies of karyotype evolution within the genus Genlisea.

In the carnivorous plant genus Genlisea a unique lobster pot trapping mechanism supplements nutrition in nutrient-poor habitats. A wide spectrum of microbes frequently occurs in Genlisea’s leaf-derived traps without clear relevance for Genlisea carnivory. We sequenced the metatranscriptomes of subterrestrial traps versus the aerial chlorophyll-containing leaves of G. nigrocaulis and of G. hispidula. Ribosomal RNA assignment revealed soil-borne microbial diversity in Genlisea traps, with 92 genera of 19 phyla present in more than one sample. Microbes from 16 of these phyla including proteobacteria, green algae, amoebozoa, fungi, ciliates and metazoans, contributed additionally short-lived mRNA to the metatranscriptome. Furthermore, transcripts of 438 members of hydrolases (e.g. proteases, phosphatases, lipases), mainly resembling those of metazoans, ciliates and green algae, were found. Compared to aerial leaves, Genlisea traps displayed a transcriptional up-regulation of endogenous NADH oxidases generating reactive oxygen species as well as of acid phosphatases for prey digestion. A leaf-versus-trap transcriptome comparison reflects that carnivory provides inorganic P- and different forms of N-compounds (ammonium, nitrate, amino acid, oligopeptides) and implies the need to protect trap cells against oxidative stress. The analysis elucidates a complex food web inside the Genlisea traps, and suggests ecological relationships between this plant genus and its entrapped microbiome.

• Background Various groups of flowering plants reveal profound ('saltational') changes of their bauplans (architectural rules) as compared with related taxa. These plants are known as morphological misfits that appear as rather large morphological deviations from the norm. Some of them emerged as morphological key innovations (perhaps 'hopeful monsters') that gave rise to new evolutionary lines of organisms, based on (major) genetic changes. • Scope This pictorial report places emphasis on released bauplans as typical for bladderworts (Utricularia, approx. 230 secies, Lentibulariaceae) and river-weeds (Podostemaceae, three subfamilies, approx. 54 genera, approx. 310 species). Bladderworts (Utricularia) are carnivorous, possessing sucking traps. They live as submerged aquatics (except for their flowers), as humid terrestrials or as epiphytes. Most Podostemaceae are restricted to rocks in tropical river-rapids and waterfalls. They survive as submerged haptophytes in these extreme habitats during the rainy season, emerging with their flowers afterwards. The recent scientific progress in developmental biology and evolutionary history of both Lentibulariaceae and Podostemaceae is summarized. • Conclusions Lentibulariaceae and Podostemaceae follow structural rules that are different from but related to those of more typical flowering plants. The roots, stems and leaves - as still distinguishable in related flowering plants - are blurred ('fuzzy'). However, both families have stable floral bauplans. The developmental switches to unusual vegetative morphologies facilitated rather than prevented the evolution of species diversity in both families. The lack of one-to-one correspondence between structural categories and gene expression may have arisen from the re-use of existing genetic resources in novel contexts. Understanding what developmental patterns are followed in Lentibulariaceae and Podostemaceae is a necessary prerequisite to discover the genetic alterations that led to the evolution of these atypical plants. Future molecular genetic work on morphological misfits such as bladderworts and river-weeds will provide insight into developmental and evolutionary aspects of more typical vascular plants.

It occupies a variety of wetlands and inland waters and shows a broad range of life forms. Here, we aimed to elucidate structural and functional traits in various hydric conditions. Furthermore, we intended to evaluate morpho-anatomical adaptations in correlation with life forms. Methods Morpho-anatomical characteristics typical for hydrophytes of all life forms were investigated by light microscopy on 13 Utricularia taxa, compared to one Pinguicula and two Genlisea taxa, and assessed by multivariate analyses. Results Vegetative structures of Utricularia and Genlisea showed reduced cortical, supporting, and vascular tissues. With increasing water table, leaves were thinner, and narrower or dissected, and submerged organs tended to contain chloroplasts in parenchymatic and epidermal cells. In some main stolons, an endodermis with Casparian strips was visible. Large gas chambers, including a novel 'crescent' and a special 'hollow' aerenchyma pattern, were found in amphibious to free-floating taxa. Conclusions The evolutionary transfer of carnivory from aerial to subterranean organs in Genlisea, and even more in Utricularia, coincides with a highly simplified anatomy, which is adapted to a broad variety of hydric conditions and compensates for structural innovations in the uptake of nutrients.

- Abstract
Telomeres are basic structures of eukaryote genomes. They distinguish natural chromosome ends from double-stranded breaks in DNA and protect chromosome ends from degradation or end-to-end fusion with other chromosomes. Telomere sequences are usually tandemly arranged minisatellites, typically following the formula (TAG). Although they are well conserved across large groups of organisms, recent findings in plants imply that their diversity has been underestimated. Changes in telomeres are of enormous evolutionary importance as they can affect whole-genome stability. Even a small change in the telomere motif of each repeat unit represents an important interference in the system of sequence-specific telomere binding proteins. Here, we provide an overview of telomere sequences, considering the latest phylogenomic evolutionary framework of plants in the broad sense (Archaeplastida), in which new telomeric sequences have recently been found in diverse and economically important families such as Solanaceae and Amaryllidaceae. In the family Lentibulariaceae and in many groups of green algae, deviations from the typical plant telomeric sequence have also been detected recently. Ancestry and possible homoplasy in telomeric motifs, as well as extant gaps in knowledge are discussed. With the increasing availability of genomic approaches, it is likely that more telomeric diversity will be uncovered in the future. We also discuss basic methods used for telomere identification and we explain the implications of the recent discovery of plant telomerase RNA on further research about the role of telomerase in eukaryogenesis or on the molecular causes and consequences of telomere variability.

Background and Aims Some species of Genlisea possess ultrasmall nuclear genomes, the smallest known among angiosperms, and some have been found to have chromosomes of diminutive size, which may explain why chromosome numbers and karyotypes are not known for the majority of species of the genus. However, other members of the genus do not possess ultrasmall genomes, nor do most taxa studied in related genera of the family or order. This study therefore examined the evolution of genome sizes and chromosome numbers in Genlisea in a phylogenetic context. The correlations of genome size with chromosome number and size, with the phylogeny of the group and with growth forms and habitats were also examined. Methods Nuclear genome sizes were measured from cultivated plant material for a comprehensive sampling of taxa, including nearly half of all species of Genlisea and representing all major lineages. Flow cytometric measurements were conducted in parallel in two laboratories in order to compare the consistency of different methods and controls. Chromosome counts were performed for the majority of taxa, comparing different staining techniques for the ultrasmall chromosomes. Key Results Genome sizes of 15 taxa of Genlisea are presented and interpreted in a phylogenetic context. A high degree of congruence was found between genome size distribution and the major phylogenetic lineages. Ultrasmall genomes with 1C values of <100 Mbp were almost exclusively found in a derived lineage of South American species. The ancestral haploid chromosome number was inferred to be n = 8. Chromosome numbers in Genlisea ranged from 2n = 2x = 16 to 2n = 4x = 32. Ascendant dysploid series (2n = 36, 38) are documented for three derived taxa. The different ploidy levels corresponded to the two subgenera, but were not directly correlated to differences in genome size; the three different karyotype ranges mirrored the different sections of the genus. The smallest known plant genomes were not found in G. margaretae, as previously reported, but in G. tuberosa (1C ≈ 61 Mbp) and some strains of G. aurea (1C ≈ 64 Mbp). Conclusions Genlisea is an ideal candidate model organism for the understanding of genome reduction as the genus includes species with both relatively large (∼1700 Mbp) and ultrasmall (∼61 Mbp) genomes. This comparative, phylogeny-based analysis of genome sizes and karyotypes in Genlisea provides essential data for selection of suitable species for comparative whole-genome analyses, as well as for further studies on both the molecular and cytogenetic basis of genome reduction in plants.

Las características biogeográficas de Colombia permiten la existencia de una amplia diversidad de plantas. La familia Lentibulariaceae es un grupo de plantas carnívoras conformada por los géneros Pinguicula, Genlisea y Utricularia.. Sin embargo, en el territorio colombiano son muy pocos los estudios relacionados a esta la familia de plantas carnívolas. Además, usualmente se realizan estudios con un enfoque únicamente morfológico para la identificación en esta familia, que puede ocasionar una caracterización errónea, por lo tanto, es necesaria la implementación de métodos moleculares complementarios a los métodos tradicionales. El uso de marcadores moleculares es una alternativa viable para llevar a cabo la identificación y caracterización de especies de los géneros que componen la familia Lentibulariaceae. A través de una búsqueda sistemática de información se realizó una lista de las especies de la familia Lentibulariaceae registradas en Colombia y se construyó un mapa de distribución de las especies. Adicionalmente, haciendo uso de la información encontrada en la base de datos NCBI, se seleccionó el gen rps16 correspondientes a las especies encontradas en la base de datos de la familia Lentibulariaceae. Hasta el momento 36 especies de las 360 especies de la familia Lentibulariaceae, han sido registradas en Colombia. En 28 departamentos del territorio colombiano se han registrado especies de esta familia, con una abundancia significativa en los departamentos de Vichada, Vaupés y Guainía. Finalmente, la información existente en las bases de datos revisadas respecto a la familia Lentibulariaceae es muy escasa, por lo que es necesario realizar más exploración y estudios conocer a profundidad la diversidad y evolución de las especies de la familia en el territorio Colombiano. In Colombia, very few studies related to the Lentibulariaceae family have been carried out, mainly due to the lack of interest and information related to these genera. Since there is robust molecular information on the phylogeny of Lentibulariaceae in the literature, and resorting only to the morphological approach for identification in this family can lead to erroneous characterization, it is necessary to implement alternative and complementary methods to traditional methods. The use of molecular markers is a viable alternative to carry out an identification and characterization of species of the genus Pinguicula, Genlisea and Utricularia, which make up the Lentibulariaceae family. Through this work, the species of the Lentibulariaceae family registered in Colombia will be determined and an analysis of their distribution in the Colombian territory will be made. A species distribution map was made. So far 36 species of the 360 species of the Lentibulariaceae family have been registered in Colombia. In total, in 28 departments of the Colombian territory, species of this family have been registered, with a significant abundance in the departments of Vichada, Vaupés and Guainía. The information in the databases reviewed regarding the Lentibulariaceae family in the country is very scarce, therefore, more studies are necessary for the correct characterization of the species of the family in the Colombian territory.

Pinguicula é um grupo irmão do clado composto por Genlisea e Utricularia, possuindo características plesiomórficas como as armadilhas relativamente simples, sendo suas folhas cobertas por uma mucilagem adesiva que captura presas. Genlisea possui armadilhas subterrâneas, em formato de forquilha e helicoidais em suas porções terminais, com fendas por onde pequenos organismos do solo se inserem. Já Utricularia possui armadilhas em formato de vesícula, denominadas utrículos, funcionais em meio aquoso via sucção. Na literatura, é proposta uma possível relação entre a carnivoria e altas taxas de substituição nucleotídica que ocorrem no clado Genlisea-Utricularia, pois o mecanismo ativo de captura de presas encontrado nos utrículos demanda muita energia, fazendo com que esses órgãos tenham altas taxas respiratórias. Um metabolismo respiratório maior pode resultar em uma superprodução de espécies reativas de oxigênio (ERO), moléculas sabidamente mutagênicas que podem estar relacionadas às altas taxas de mutações encontradas nos genomas do clado Genlisea-Utricularia. Além disso, esse clado possui as espécies com os menores genomas encontrados em angiospermas, fenômeno que está relacionado à ocorrência de uma acelerada evolução molecular. Foi mensurado o conteúdo de H2O2, uma das principais ERO, em vários órgãos de seis espécies de Lentibulariaceae: Pinguicula gigantea, P. agnata, Genlisea violacea, G. repens, Utricularia reniformis e U. foliosa. Foram realizadas análises filogenéticas com oito sequências, oriundas de dois compartimentos genômicos (cloroplasto e núcleo), em 114 espécies de Lentibulariaceae, inclusive as empregadas no estudo em questão. Testou-se a possível correlação entre o conteúdo de H2O2 nas folhas e o comprimento de ramos das espécies analisadas, baseando-se nas análises moleculares. Constatou-se a existência de correlação positiva entre o comprimento de ramos nas filogenias e o conteúdo de H2O2 nas folhas das espécies. Foi discutida também a origem dessa ERO nos órgãos das espécies de Lentibulariaceae, e U. foliosa foi empregada em um ensaio com essa finalidade. A influência do hábito no conteúdo de H2O2 dos órgãos também foi analisada, empregando-se U. graminifolia como modelo. Nesse caso, evidenciou-se que espécies terrestres tendem a acumular mais H2O2 em seus órgãos do que as aquáticas, que podem perder essa substância por difusão no ambiente aquático, havendo possíveis implicações evolutivas nesse fenômeno. Lentibulariaceae is a family of carnivorous plants composed by three genera, Pinguicula, Genlisea and Utricularia. Pinguicula is a sister group of the clade composed by Genlisea and Utricularia, possessing plesiomorphic characteristics such as the relatively simple traps, being its leaves covered by an adhesive mucilage that capture prey. Genlisea has underground, fork-shaped and helical traps, with slits where small soil organisms fit in. Utricularia, on the other hand, has vesicle-shaped traps, the utricles, which are functional in aqueous medium by suction. A possible relationship between carnivory and high rates of nucleotide substitution that occur in the Genlisea-Utricularia clade is discussed, because the active prey capture mechanism found in the utricles requires high energy, causing high respiratory rates in these organs. A higher respiratory metabolism can result in an overproduction of reactive oxygen species (ROS), molecules that are known to be mutagenic, and could be related with the high mutation rates found in the genomes of Genlisea-Utricularia clade. In addition, this clade has the species with the smallest genomes found in angiosperms, a phenomenon that is related with high molecular rates. The content of H2O2, one of the main ROS, was measured in several organs of six species of Lentibulariaceae: Pinguicula gigantea, P. agnata, Genlisea violacea, G. repens, Utricularia reniformis and U. foliosa. Phylogenetic analyzes were carried out with eight sequences, from two genomic compartments (chloroplast and nucleus), in 114 species of Lentibulariaceae, including those used in this study. The possible relationship between the content of H2O2 in leaves and the branch length of the analyzed species was tested, based on molecular estimates. It was found positive correlation between the trees branch lengths in phylogenies and the content of H2O2 in leaves. The origin of this ROS in the organs of Lentibulariaceae species was also discussed, and U. foliosa was used in an assay for this purpose. The influence of the habit in the accumulation of H2O2 in the organs was also analyzed, using U. graminifolia as a model. In this case, we demonstrate that terrestrial species accumulate more H2O2 in their organs than the aquatic ones, because they can lose this substance by diffusion in the aquatic environment, with possible evolutionary implications.

Telomeres are basic structures of eukaryote genomes. They distinguish natural chromosome ends from double-stranded breaks in DNA and protect chromosome ends from degradation or end-to-end fusion with other chromosomes. Telomere sequences are usually tandemly arranged minisatellites, typically following the formula (TAG). Although they are well conserved across large groups of organisms, recent findings in plants imply that their diversity has been underestimated. Changes in telomeres are of enormous evolutionary importance as they can affect whole-genome stability. Even a small change in the telomere motif of each repeat unit represents an important interference in the system of sequence-specific telomere binding proteins. Here, we provide an overview of telomere sequences, considering the latest phylogenomic evolutionary framework of plants in the broad sense (Archaeplastida), in which new telomeric sequences have recently been found in diverse and economically important families such as Solanaceae and Amaryllidaceae. In the family Lentibulariaceae and in many groups of green algae, deviations from the typical plant telomeric sequence have also been detected recently. Ancestry and possible homoplasy in telomeric motifs, as well as extant gaps in knowledge are discussed. With the increasing availability of genomic approaches, it is likely that more telomeric diversity will be uncovered in the future. We also discuss basic methods used for telomere identification and we explain the implications of the recent discovery of plant telomerase RNA on further research about the role of telomerase in eukaryogenesis or on the molecular causes and consequences of telomere variability., This work was supported by ERDF [project SYMBIT, reg. no.

Within Genlisea, only G. tuberosa, from the Brazilian Cerrado, formed tubers, while Utricularia menziesii is the only member of the genus to form seasonally dormant tubers. We aimed to examine and compare the tuber structure of two taxonomically and phylogenetically divergent terrestrial carnivorous plants: Genlisea tuberosa and Utricularia menziesii. Additionally, we analyzed tubers of U. mannii. We constructed phylogenetic trees using chloroplast genes matK/trnK and rbcL and used studied characters for ancestral state reconstruction. All examined species contained mainly starch as histologically observable reserves. The ancestral state reconstruction showed that specialized organs such as turions evolved once and tubers at least 12 times from stolons in Lentibulariaceae. Different from other clades, tubers probably evolved from thick stolons for sect. Orchidioides and both structures are primarily water storage structures. In contrast to species from section Orchidioides, G. tuberosa, U. menziesii and U. mannii form starchy tubers. In G. tuberosa and U. menziesii, underground tubers provide a perennating bud bank that protects the species in their fire-prone and seasonally desiccating environments.

Very few studies have addressed the genetic structure and conservation status of G. aurea and the Lentibulariaceae. Microsatellites markers are advantageous tools that can be employed to predict the vulnerability of Lentibulariaceae species. Therefore, the development of molecular markers focusing the population analyses of Genlisea for future genetic studies and conservation actions are essential. Thus, we developed simple sequence repeats (SSRs) based on in silico analyses of G. aurea draft genome assembly. We characterized 40 individuals from several populations and identified 12 loci that were polymorphic, with heterozygosity between 0.123 and 0.650. We demonstrated that the G. aurea SSR markers work cross-species in Genlisea filiformis, G. repens, G. tuberosa and G. violacea. These markers will be important for future population, phylogeographic and conservation studies in G. aurea and other Genlisea species.

Abstract: The carnivorous plant genus Genlisea A. St.-Hil. (Lentibulariaceae) comprises at least 22 species distributed in South and Central America as well as in Africa (including Madagascar). It has only recently been shown to be a true carnivore, specialized in protozoa and other small soil organisms. Here we present a statistically highly supported phylogeny of Genlisea based on three chloroplast loci. The most recent common ancestor of Genlisea most likely was of Neotropical origin and characterized by pedicels that are recurved in fruit, a strongly glandular inflorescence, and bivalvate capsule dehiscence. The further evolution of various morphological characters during the diversification of the genus is discussed. The two previously suggested subgenera Tayloria and Genlisea correspond to the two major clades found in our analyses. In subgenus Genlisea, three clades can be clearly distinguished based on molecular and morphological characters and on biogeographic patterns, which led us to propose a new sectional classification.

Resumo Lentibulariaceae é cosmopolita e possui três gêneros, Genlisea, Pinguicula e Utricularia, com cerca de 29, 100 e 220 espécies, respectivamente. O Parque Nacional do Itatiaia possui relevo bastante acidentado, onde encontram-se muitas nascentes de rios, lagos e uma grande diversidade de bromélias. Assim, sua vegetação e seus ambientes são habitats propícios para a ocorrência de espécies de Lentibulariaceae. Os estudos sobre estas espécies no local são, todavia, escassos e restritos a antigas listagens de espécies. Apresentamos aqui o tratamento florístico completo para as Lentibulariaceae do Parque Nacional do Itatiaia. Foram registradas oito espécies, todas pertencentes ao gênero Utricularia. As espécies foram encontradas ocorrendo em corpos d'água da parte alta do parque, sendo que somente U. reniformis ocorre também nos riachos da parte baixa do parque. É apresentada uma chave de identificação para as espécies ocorrentes, além de descrições detalhadas de cada espécie, comentários e fotografias.

- Abstract
Various ecophysiological investigations on carnivorous plants in wet soils are presented. Radial oxygen loss from roots of Droseraceae to an anoxic medium was relatively low 0.02 – 0.07 μmol(O
2 ) m− 2 s−1 in the apical zone, while values of about one order of magnitude greater were found in both Sarracenia rubra roots and Genlisea violacea traps. Aerobic respiration rates were in the range of 1.6 − 5.6 μmol kg−1 (f.m.) s−1 for apical root segments of seven carnivorous plant species and 0.4 − 1.1 μmol kg−1 (f.m.) s−1 for Genlisea traps. The rate of anaerobic fermentation in roots of two Drosera species was only 5 − 14 % of the aerobic respiration. Neither 0.2 mM NaN3 nor 0.5 mM KCN influenced respiration rate of roots and traps. In all species, the proportion of cyanide-resistant respiration was high and amounted to 65 − 89 % of the total value. Mean rates of water exudation from excised roots of 12 species ranged between 0.4 − 336 mm 3 kg−1 (f.m.) s−1 with the highest values being found in the Droseraceae. Exudation from roots was insensitive to respiration inhibitors. No significant difference was found between exudation rates from roots growing in situ in anoxic soil and those kept in an aerated aquatic medium. Carnivorous plant roots appear to be physiologically very active and well adapted to endure permanent soil anoxia. [ABSTRACT FROM AUTHOR]- Published

This study reveals that U. foliosa have a typical chloroplast genome of 150,851 bp in length, comprised of a large single-copy region (LSC) of 82,720 bp, a small single-copy region (SSC) of 17,481 bp, and inverted repeat regions (IRs) of 25,325 bp. A total of 139 genes, 88 of which are protein coding genes, 37 tRNA genes, eight rRNA genes and six pseudogenes were identified. All plastid NAD(P)H-dehydrogenase genes are present as intact copies. Phylogenetic analyses indicate that U. foliosa is closely related to other suspended or affixed aquatic species belonging to the Utricularia sect. Utricularia.

Linear chromosomes of eukaryotic organisms invariably possess centromeres and telomeres to ensure proper chromosome segregation during nuclear divisions and to protect the chromosome ends from deterioration and fusion, respectively. While centromeric sequences may differ between species, with arrays of tandemly repeated sequences and retrotransposons being the most abundant sequence types in plant centromeres, telomeric sequences are usually highly conserved among plants and other organisms. The genome size of the carnivorous genus Genlisea (Lentibulariaceae) is highly variable. Here we study evolutionary sequence plasticity of these chromosomal domains at an intrageneric level. We show that Genlisea nigrocaulis (1C = 86 Mbp; 2n = 40) and G. hispidula (1C = 1550 Mbp; 2n = 40) differ as to their DNA composition at centromeres and telomeres. G. nigrocaulis and its close relative G. pygmaea revealed mainly 161 bp tandem repeats, while G. hispidula and its close relative G. subglabra displayed a combination of four retroelements at centromeric positions. G. nigrocaulis and G. pygmaea chromosome ends are characterized by the Arabidopsis-type telomeric repeats (TTTAGGG); G. hispidula and G. subglabra instead revealed two intermingled sequence variants (TTCAGG and TTTCAGG). These differences in centromeric and, surprisingly, also in telomeric DNA sequences, uncovered between groups with on average a > 9-fold genome size difference, emphasize the fast genome evolution within this genus. Such intrageneric evolutionary alteration of telomeric repeats with cytosine in the guanine-rich strand, not yet known for plants, might impact the epigenetic telomere chromatin modification.

Tayloria (Lentibulariaceae) from cerrado in southwest Brazil, is described and illustrated. This species has been found in only one locality thus far, in the Serra da Canastra, which is located in the Delfinópolis municipality in Minas Gerais, Brazil. The new species is morphologically similar to Genlisea violacea and G. flexuosa, but differs from them in having a corolla with a conical and curved spur along with sepals with an acute apex and reproductive organs that only have glandular hairs. Moreover, it is similar to G. uncinata’s curved spur. G. hawkingii is nested within the subgen. Tayloria clade as a sister group to all the other species of this subgenus. Therefore, both morphological and phylogenetic results strongly support G. hawkingii as a new species in the subgen. Tayloria.

Made available in DSpace on 2018-12-11T17:18:01Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-07-01 In the genus Genlisea as well as in its sister genus Utricularia, the palate probably plays a key role in providing the colour, mechanical and olfactory stimuli to attract insect pollinators and to guide them to the generative structures and the nectary spur. However, information about the micro-morphology of the palate of Genlisea is scarce. This study aims to examine the structure of the palate in Genlisea hispidula in detail as well as the palate from other five species from the subgenus Genlisea. In particular, its aim is to ascertain whether these palates function as an area for the osmophores in the flower or whether they produce nectar. We showed that the palate in all of the species that were examined was the glandular type and that it had capitate, glandular trichomes, which had a similar general architecture across the species that were examined. No nectar secretion was observed on the palates. The ultrastructure of the palate trichomes showed that the palate glandular trichomes most probably function as scent glands that produce an olfactory stimulus for flower pollinators.

Possuem aproximadamente 260 espécies representadas em diversas formas de vida. Para o Brasil foram catalogadas 82 espécies, das quais 27 são consideradas endêmicas. Além de dispor das armadilhas carnívoras mais complexas entre plantas, algumas de suas espécies apresentam os menores genomas e as maiores taxas de mutações entre as angiospermas relatadas até o momento. A respeito de seus genomas organelares, os estudos são pífios. Neste contexto, há a necessidade de se investigar como são os genomas organelares, suas estruturas, seus genes e como se deu a evolução das organelas nos gêneros. Portanto este estudo teve como objetivo, a partir de sequenciamento de nova geração e montagem de genomas, estudar e comparar os genomas organelares de Utricularia e Genlisea. Neste âmbito, foram montados e sequenciados os cloroplastos das espécies Utricularia foliosa, U. reniformis, G. aurea, G. filiformis, G. pygmaea, G. repens e G. tuberosa, e o genoma mitocondrial de U. reniformis. Os resultados obtidos revelaram que possivelmente há relação entre forma de vida e presença de genes ndhs nos gêneros, em razão de que para as espécies terrestres há deleção e “pseudogenização” de genes ndhs, já as espécies aquáticas detêm todo repertório de ndhs intacto. A partir das evidências encontradas, foi possível constatar transferência horizontal de genes, inclusive de genes ndhs, em mitocôndrias. Utricularia and Genlisea are sister genera in the carnivorous family Lentibulariaceae. There are aprproximately 260 species representing diverse life forms. For Brasil there are 82 species, 27 considered endemic. At the moment, besides having the most complex carnivorous traps between all plants, some of its species have miniature genomes and the highest mutational rates among angiosperms. There are few studies regarding its organellar genome. In this context, it is necessary to investigate how are these organellar genomes, its structure, genes, and how evolutionary forces govern these organelles in the different genera. Therefore, the aim of this study is to study and compare the organellar genomes of Utricularia and Genlisea, using next generation sequencing and genome assembly. In this context, chloroplasts of the species Utricularia foliosa, U. reniformis, Genlisea aurea, G. filiformis, G. pygmaea, G. repens and G. tuberosa, and the mitochondrial genome of U. reniformis were assembled and sequenced. The results show that possibly there is a connection between life form and the presence of ndhs genes in the genera, since for the terrestrial species there are ndhs genes that are deleted and pseudogenization, in contrary to the aquatic species which have all intact ndhs repertoir. Concerning the evidences, it was possible to verify horizontal transfer of ndhs and other genes as there are chloroplasts genes in the mitochondria.

We review the current knowledge of trap anatomy of carnivorous plants, with a focus on the diversity and structure of the glands that are used to attract, capture, kill and digest their prey and finally to absorb nutrients from carcasses of prey. These glands have diverse forms. Regardless of their structure and origin, they have the same functional units, but there are differences in subcellular mechanisms and adaptations for carnivory. We propose a new type of carnivorous plant trap—a ‘fecal traps—which has unique physiology, morphology, and anatomy for attracting the animals that are the source of excrement and also to retain and use it.
