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

Six patchouli (Pogostemon cablin Benth.) plants showing symptoms of viral infection were found in Brazil. Transmission electron microscopy revealed flexuous particles and characteristic pinwheel‐shaped cytoplasmic inclusions of potyvirus in sap and cells of symptomatic leaves. Potyvirus infection was confirmed through RT‐PCR, using universal primers followed by nucleotide sequencing. The obtained sequences, comprising part of the CP gene and the 3′ non‐translated region, showed 97.71%–97.87% identity with an isolate of bidens mosaic virus (BiMV). The nucleotide sequences of the CP, HC‐Pro and CI genes of BiMV isolates from patchouli plants were obtained through RT‐PCR with specific primers followed by nucleotide sequencing. The obtained sequences showed 95.78%–97.1% identities with BiMV isolates from Brazil. One BiMV isolate from a patchouli infected plant was sap‐transmitted to different plant species. Chenopodium amaranticolor exhibited local lesions, Bidens pilosa developed leaf mosaic, and Nicotiana benthamiana exhibited chlorosis and stunting. The BiMV isolate was transmitted from infected patchouli plant to B. pilosa using Myzus persicae aphids. This is the first confirmation of patchouli infected with BiMV in Brazil. Further studies are necessary to assess the incidence of this potyvirus in commercial patchouli crops, as well as the damage caused to plant development and the quantity and quality of essential oils produced.

Abstract

This contribution describes biological and molecular features of an isolate of the chrysanthemum stem necrosis orthotospovirus (CSNV) found naturally infecting sweet pepper plants (Capsicum annuum L.). High‐throughput sequencing resulted in three contig sequences of 2948, 4829 and 8959 nucleotides for CSNV‐Ca small, medium and large RNAs, respectively. They shared 98.4%, 99.3% and 99.1% nucleotide identities, respectively, with the corresponding nucleotide sequences of a CSNV isolate from Slovenia. The virus was mechanically transmitted to sweet pepper and some additional test plants, and RT‐PCR confirmed the infection with specific primers for CSNV. Additionally, transmission electron microscopic analysis of ultrathin sections prepared from symptomatic sweet pepper fruit tissue showed orthotospoviruses‐like particles in elements of the endoplasmic reticulum. Studies are needed to evaluate the occurrence of CSNV infecting sweet pepper in commercial crops, to assess yield damage and develop recommendations for management. [ABSTRACT FROM AUTHOR]

Abstract

Brevipalpus yothersi egg morphology Details of external eggs morphology could be followed under SEM. Transverse streaks in the outer layer of the eggs called carenas (Rodrigues and Machado 1999) (Figure 2a) and a fold-like structure in the equatorial region of the egg (Figure 2b). An external globular structure were observed in studies by Rodrigues and Machado (1999). However, it was observed only in eggs with a more advanced development time but morphologically different from the one found in our study. Eggshells frequently broke during fixation in Carnoy’s solution, allowing for observation of the internal structure of eggs. Additionally, channels similar to small perforations were seen extending between the shell and intermediate lamella (Figure 3). These channels may be associated with the respiratory tract of the embryo. Such structures were also observed by Dittrich (1971) in studies with T. urticae, and they have been shown to give mites protection against desiccation and gas exchange., Published as part of Sinico, Thaís Elise, Nunes, Maria Andréia, Kitajima, Elliot Watanabe, Cunha, Bruna Aparecida & Novelli, Valdenice Moreira, 2022, Notes on the embryological development of the Brevipalpus yothersi (Acari: Tenuipalpidae), pp. 113-119 in Acarologia 62 (1) on page 116, DOI: 10.24349/0gr3-3a6b, http://zenodo.org/record/7160131, {"references":["Rodrigues J.

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

Citrus leprosis (CL) is a viral disease currently affecting citrus orchards in Latin America. It causes a non-systemic infection that produces necrotic and chlorotic spots in leaves, stems and fruits, reducing citrus crop yield and leading to the death of younger trees. Viruses causing CL are assigned to two genera: Cilevirus [bipartite ss(+) RNA] and Dichorhavirus [bipartite ss(-) RNA]. Prevalent CL in orchards from Mexico to Argentina is the cytoplasmic type of the disease (CL-C) produced by the cilevirus citrus leprosis virus C (CiLV-C). CiLV-C population is genetically subdivided into two clades, which have a contrasted geographic distribution. While viruses from one clade seem to be confined to commercial areas in the State of São Paulo, Brazil, those from the other occur all over the continent. In Colombia, CL-C is also caused by another cilevirus, CiLV-C2, whose genome shares only 55% nucleotide identity with CiLV-C. Nuclear types of leprosis (CL-N), caused by dichorhaviruses, seem to have severely affected citrus orchards in Florida, USA, a century ago, and have been recently characterized in Brazil, Mexico and Colombia. While in the two latter countries citrus strains of orchid fleck virus (OFV-citrus) occur in commercial orchards, in Brazil, citrus leprosis virus N (CiLV-N) and citrus chlorotic spot virus (CiCSV) are the causal agents for CL-N so far, which are restricted to small non-commercial areas. Both, CiLV-N and CiCSV, display a relatively distant phylogenetic relationship with OFV (< 65% nucleotide sequence identity). All viruses causing CL are persistently transmitted by false spider mites of the genus Brevipalpus, but with distinguishing features for cilevirus and dichorhavirus. A large spectrum of citrus commercial species and hybrids are prone to CL infection, and the apparent symptoms, at least in sweet oranges infected by CiLV-C, seem to be the outcome of a hypersensitive-like response. Studies based on molecular epidemiology and omics approaches are providing the necessary insights to generate more effective and safer control strategies of CL.
