The family Rhabdoviridae comprises viruses with negative-sense (−) RNA genomes of 10–16 kb. Virions are typically enveloped bullet-shaped or bacilliform morphology but can also be non-enveloped filaments. Rhabdoviruses infect plants animals, including mammals, birds, reptiles, amphibians fish, as well arthropods, which serve single hosts act biological vectors for transmission to animals plants. include important pathogens humans, livestock, fish agricultural crops. This is a summary the...
Abstract Background The western flower thrips, Frankliniella occidentalis (Pergande), is a globally invasive pest and plant virus vector on wide array of food, fiber, ornamental crops. underlying genetic mechanisms the processes governing thrips biology, feeding behaviors, ecology, insecticide resistance are largely unknown. To address this gap, we present F. draft genome assembly official gene set. Results We report first sequence for any member insect order Thysanoptera. Benchmarking...
Rhabdoviruses infect a large number of plant species and cause significant crop diseases. They have negative-sense, single-stranded unsegmented or bisegmented RNA genome. The plant-associated rhabdovirid sequences has grown in the last few years concert with extensive use high-throughput sequencing platforms. Here, we report discovery 27 novel rhabdovirus genomes associated 25 different host one insect, which were hidden public databases. These viral identified through homology searches more...
The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex that contains some of the most damaging pests in tropical and subtropical regions. Recent studies suggested this composed at least 24 distinct species. We use approach from these to consider identity B. Argentina. Previous have presence presumably indigenous Americas referred as BR biotype placed entity within using whiteflies collected soybean bean crops northern central were assigned mitochondrial...
The genus Varicosavirus is one of six genera plant-infecting rhabdoviruses. Varicosaviruses have non-enveloped, flexuous, rod-shaped virions and a negative-sense, single-stranded RNA genome. A distinguishing feature varicosaviruses, which shared with dichorhaviruses, bi-segmented Before 2017, sole varicosavirus was known characterized, then two more varicosaviruses were identified through high-throughput sequencing in 2017 2018. More recently, the number has substantially increased concert...
Improved RNA virus understanding is critical to studying animal and plant health, environmental processes. However, the continuous rapid evolution makes their identification characterization challenging. While recent sequence-based advances have led extensive discovery, there growing variation in how viruses are identified, analyzed, characterized, reported. To this end, an RdRp Summit was organized a hybrid meeting took place Valencia, Spain May 2023 convene leading experts with emphasis on...
Cytorhabdoviruses (genus Cytorhabdovirus, family Rhabdoviridae) are plant-infecting viruses with enveloped, bacilliform virions. Established members of the genus Cytorhabdovirus have unsegmented single-stranded negative-sense RNA genomes (ca. 10–16 kb) which encode four to ten proteins. Here, by exploring large publicly available metatranscriptomics datasets, we report identification and genomic characterization 93 novel genetic evolutionary cues cytorhabdoviruses. Strikingly, five...
Ophioviruses (genus Ophiovirus, family Aspiviridae) are plant-infecting viruses with non-enveloped, filamentous, naked nucleocapsid virions. Members of the genus Ophiovirus have a segmented single-stranded negative-sense RNA genome (ca. 11.3-12.5 kb), encompassing three or four linear segments. In total, these segments encode to seven proteins in sense and antisense orientation, both viral complementary strands. The includes species infecting monocots dicots, mostly trees, shrubs some...
The European grapevine moth (Lobesia botrana) poses a significant threat to vineyards worldwide, causing extensive economic losses. While its ecological interactions and control strategies have been well studied, associated viral diversity remains unexplored. Here, we employ high-throughput sequencing data mining comprehensively characterize the L. botrana virome, revealing novel diverse RNA viruses. We characterized four new members belonging distinct families, with evolutionary cues of...
Given the agronomic and economic importance of viticulture, grapevine has been shown to host largest number viruses among plants date. Nevertheless, studies assessing grapevine-associated holobiont remain scarce. In this context, viral component ecological niche is understudied. work, through metatranscriptomics wood samples from individual grapevines that were either healthy or exhibited symptoms trunk disease Argentina, we provide a glimpse into linked virome. Virus discovery...
Abstract Nucleorhabdoviruses, classified into four distinct genera within the family Rhabdoviridae (subfamily Betarhabdovirinae ), are plant-infecting viruses, characterized by nucleus-associated, enveloped, bacilliform virions. Nucleorhabdoviruses possess an unsegmented, single-stranded, negative-sense RNA genome (ca. 12-15.2 kb) that encodes six to eight proteins. Here, exploring large publicly available metatranscriptomics datasets, we report identification and genomic characterization of...
