Abstract

Two novel members of the subfamily Betarhabdovirinae, family Rhabdoviridae, were identified in Brazil. Overall, their genomes have the typical organization 3′-N-P-P3-M-G-L-5′ observed in mono-segmented plant-infecting rhabdoviruses. In aristolochia-associated cytorhabdovirus (AaCV), found in the liana aristolochia (Aristolochia gibertii Hook), an additional short orphan ORF encoding a transmembrane helix was detected between P3 and M. The AaCV genome and inferred encoded proteins share the highest identity values, consistently < 60%, with their counterparts of the yerba mate chlorosis-associated virus (Cytorhabdovirus flaviyerbamate). The second virus, false jalap virus (FaJV), was detected in the herbaceous plant false jalap (Mirabilis jalapa L.) and represents together with tomato betanucleorhabdovirus 2, originally found in tomato plants in Slovenia, a tentative new species of the genus Betanucleorhabdovirus. FaJV particles accumulate in the perinuclear space, and electron-lucent viroplasms were observed in the nuclei of the infected cells. Notably, distinct from typical rhabdoviruses, most virions of AaCV were observed to be non-enclosed within membrane-bounded cavities. Instead, they were frequently seen in close association with surfaces of mitochondria or peroxisomes. Unlike FaJV, AaCV was successfully graft-transmitted to healthy plants of three species of the genus Aristolochia, while mechanical and seed transmission proved unsuccessful for both viruses. Data suggest that these viruses belong to two new tentative species within the subfamily Betarhabdovirinae. [ABSTRACT FROM AUTHOR]

Abstract

The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo nomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world’s known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world’s most biodiverse countries. We further identify collection gaps and summarize future goals that extend be yond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still un equally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the coun try. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora.

Abstract

In April 2022, Aristolochia plants with symptoms of mosaic were observed in a garden at Jardim Botânico Plantarum, Nova Odessa, São Paulo State, Brazil. Potyviridae‐like particles were observed by transmission electron microscopy in leaf extracts. Total RNA extracted from symptomatic plants used in RT‐PCR with universal and BCMV‐specific primers detected the potyvirus bean common mosaic virus (BCMV). The cucumovirus cucumber mosaic virus (CMV) was identified only in Aristolochia littoralis plants that tested negative by RT‐PCR for BCMV. Phylogenetic analysis grouped samples of Aristolochia in a different clade among samples of Phaseolus vulgaris. Phylogenetic analysis indicated that the CMV isolate from Aristolochia belongs to the CMV group IA. BCMV was mechanically transmitted to healthy plants of A. fimbriata, Chenopodium quinoa, P. vulgaris cv. Jalo and Macroptilium lathyroides. CMV was mechanically transmitted to plants of A. fimbriata and C. quinoa. The BCMV and CMV were aphid transmitted only by Aphis gossypii to Aristolochia plants. This is the first report of BCMV and CMV infecting Aristolochia plants in Brazil. [ABSTRACT FROM AUTHOR]

Abstract

The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora.

Abstract

The chemical composition and antimicrobial activity of essential oils obtained from three Brazilian plant species-leaves and branches of Eremanthus erythropappus (Asteraceae), leaves of Plectranthus barbatus, and leaves of P. amboinicus (Lamiaceae)-were determined. Analysis by GC/MS and determination of Kovats indexes both indicated δ-elemene (leaves-42.61% and branches-23.41%) as well as (-)-α-bisabolol (leaves-24.80% and stem bark-66.16%) as major constituents of E. erythropappus essential oils. The main components of leaves of P. barbatus were identified as (Z)-caryophyllene (17.98%), germacrene D (17.35%), and viridiflorol (14.13%); whereas those of leaves of P. amboinicus were characterized as p-cymene (12.01%), γ-terpinene (14.74%), carvacrol (37.70%), and (Z)-caryophyllene (14.07%). The antimicrobial activity against yeasts and bacteria was assessed in broth microdilution assays to determine the minimum inhibitory concentration (MIC) necessary to inhibit microbial growth. In addition, the crude oil of branches of E. erythropappus was subjected to chromatographic separation procedures to afford purified (-)-α-bisabolol. This compound displayed biological activity against pathogenic yeasts, thus suggesting that the antimicrobial effect observed with crude oils of E. erythropappus leaves and branches may be related to the occurrence of (-)-α-bisabolol as their main component. Our results showed that crude oils of Brazilian plants, specifically E. erythropappus, P. barbatus, and P. amboinicus and its components, could be used as a tool for the developing novel and more efficacious antimicrobial agents.

17. Antitrypanosomal Activity of a Diterpene and Lignans Isolated from Aristolochia cymbifera.

Abstract

Bioguided fractionation of extract from the leaves of Aristolochia cymbifera led to the isolation of the furofuran lignans fargesin, epieudesmin, and sesamin; the dibenzylbutyrolactone lignans hinokinin and kusunokinin; and an ent-labdane diterpene named copalic acid. Our data demonstrated that copalic acid and kusunokinin were the most active compounds against trypomastigotes of Trypanosoma cruzi. Additionally, copalic acid demonstrated the highest parasite selectivity as a result of low toxicity to mammalian cells, despite a considerable hemolytic activity at higher concentrations. Among the isolated compounds, kusunokinin could be considered the most promising candidate, as it displayed significant activity against intracellular amastigotes (IC50 = 17 �M) and trypomastigotes (IC50 = 51 �M) without hemolytic activity. Fargesin, hinokinin, epieudesmin, and sesamin were also effective against trypomastigotes, but these compounds were highly toxic to mammalian cells and no parasite selectivity could be identified. The need for novel drugs for American trypanosomiasis is evident, and these secondary metabolites from A.�cymbifera represent a useful tool for drug design. [ABSTRACT FROM AUTHOR]

18. Effects of common cocklebur control systems on soybean yields, costs, and returns

Author

Lorenzi, Harri Jose

Abstract

Common cocklebur (Xanthium pensylvanicum Wallr.) and other common weeds growing in soybean fields must be controlled in order to obtain maximum soybean yields. Many methods for achieving good weed control are available, however the cost and returns from these various systems are important, since partial weed control or even total control may or may not be economically favorable. The efficiency of weed control methods in soybeans should always be evaluated in conjunction with a detailed study of economic returns. Field studies were conducted in Tennessee during 1975 and 1976 under conventional tillage cropping at two locations, and during 1978 under no-tillage cropping at one location. These studies were conducted to determine: (1) the efficiency of various weed control systems for control of common cocklebur and other weeds, and (2) the effects of various levels of control of common cocklebur and other weeds on soybean yields, and the cost and returns from each level of control. In the conventional tillage experiments profluralin at 0.8 kg/ha was applied to the whole experimental area to control annual grasses and followed by sequential applications of pre and postemergence herbicides followed by between row cultivation to control cocklebur and other annual broadleaf weeds. Naptalam + dinoseb (Dyanap) at rate of 5.0 kg/ha was applied preemergence followed by postemergence applications at the second trifoliate stage of the soybeans of either bentazon at the rate of 0.8 kg/ha, or dinoseb at 0.8 kg/ha, or Dyanap at 2.5 kg/ha. These combinations were followed either by bentazon at 0.8 kg/ha or cultivation when the soybeans were 30-70cm tall, with other cultivations as needed later in the season. Also as separate treatments either linuron at 0.5 kg/ha or metribuzin at 0.6 kg/ha were applied at the preemergence stage or Dyanap at 4.2 kg/ha was applied at the cracking stage. None of these were followed by a postemergence treatment at the second trifoliate stage. These treatments were followed by either bentazon or cultivation when soybeans were 30-70cm tall plus other cultivation as needed later in the season. In the no-tillage experiment, glyphosate at 1.7 kg/ha was applied at planting over the whole experimental area. This was followed by metribuzin at 0.6 kg/ha and alachlor at 2.2 kg/ha applied preemergence singly or mixed to each plot. Thirty days later two new postemergence herbicides coded as RH-6201 at 2.2 kg/ha and HOE-29152 at 0.6 kg/ha, were applied singly or in combination over plots previously treated with the preemergence herbicides. Under conventional tillage all weed control methods increased yields, except Dyanap applied preemergence with no further treatment. Greatest soybean yields were produced with practices most effective for cocklebur control. The inclusion of the third treatment of bentazon or cultivation when the soybeans were 30-70cm tall followed by cultivation later in the season resulted in maximum yields. A postemergence treatment applied at second trifoliate stage of soybeans was not necessary if linuron was the preemergence treatment and bentazon was applied when soybeans were 30-70cm and followed by timely cultivation later in the season. A single post-emergence application of bentazon when the soybeans were 30-70cm tall followed by cultivation later in the season was enough to produce maximum yields, even when no prior treatment was made. (In all treatments profluralin had controlled the annual grasses.) The predicted adjusted yields ranged from 509-1748 kg/ha with 0% control of cocklebur to 2528-3161 kg/ha with 100% control. Total costs of production ranged from $142-167/ha with no cocklebur control to $207-228/ha with 100% control. An additional investment of $18-24/ha was required to increase common cocklebur control from 60 to 95%. Net returns were increased with all common cocklebur control measures, except where Dyanap was applied at either the preemergence or cracking stage without a subsequent treatment. Maximum net returns were obtained in all experiments when Dyanap was applied at the cracking stage and metribuzin was applied preemergence, if these treatments were followed by bentazon applied when the soybeans were 30-70cm tall and were cultivated later in the season. A single application of bentazon when the soybeans were 30-70cm tall, followed by cultivation later in the season with no prior treatments was enough to produce maximum net returns in each experiment, except at Ames Plantation in 1976. Bentazon applied when the soybeans were 30-70cm tall followed by cultivation later in the season contributed for maximum net returns when Dyanap was applied at the cracking stage, and when metribuzin was applied in preemergence. Failure to provide any control of common cocklebur resulted in net returns ranging from $-21 to $185/ha, according to the predicted regression equation developed to estimate the effects of these two variables. Control of 95% of common cocklebur resulted in net returns ranging from $310 to $416/ha. According to these results the best cocklebur control systems for conventional tillage soybeans were: either Dyanap applied at the cracking stage or metribuzin applied preemergence, both followed by bentazon applied when the soybeans were 30-70cm tall followed by cultivation later in the season. Under no-tillage cropping none of the weed control measures tested significantly increased soybean yields or net returns when compared to the untreated control. This was partially due to poor soybean stands resulting from severe rabbit damage. Predicted adjusted yields of 509 kg/ha were calculated for 0% of weed control and 1547 kg/ha for 100-6 control. Maximum weed control was provided by all herbicide combinations that included metribuzin + RH-6201. These combinations provided an average of 90% weed control.
