Comprehensive inventories of plant viral diversity are essential for effective quarantine and sanitation efforts. The safety regulated material exchanges presently relies heavily on techniques such as PCR or nucleic acid hybridisation, which only suited to the detection characterisation specific, well characterised pathogens. Here, we demonstrate utility sequence-independent next generation sequencing (NGS) both virus-derived small interfering RNAs (siRNAs) virion-associated acids (VANA)...
Abstract We here assessed the capability of MinION sequencing approach to detect and characterize viruses infecting a water yam plant. This platform consistently revealed presence several plant virus species, including Dioscorea bacilliform , Yam mild mosaic chlorotic necrosis . A potentially novel ampelovirus was also detected by complimentary Illumina approach. The full-length genome sequence determined using Sanger sequencing, which enabled determination coverage accuracy technology....
SUMMARY The genome of Musa balbisiana spp. contains several infectious endogenous sequences Banana streak virus (eBSV). We have shown previously that in vitro micropropagation triggers the activation eBSOLV (endogenous Obino l'Ewai ) synthetic tetraploid interspecific hybrid FHIA21 (AAAB). In this work, we show another (AAAB) and two natural triploid (AAB) plantains are equally prone to during tissue culture. These results a strong indication such is general phenomenon cultivars, whether or...
Banana bunchy top virus (BBTV) is a six-component ssDNA (genus Babuvirus , family Nanoviridae ) transmitted by aphids, infecting monocots (mainly species in the Musaceae) and likely originating from South-East Asia where it frequently associated with self-replicating alphasatellites. Illumina sequencing analysis of banana aphids leaf samples Africa revealed an alphasatellite that should be classified new genus, phylogenetically related to alphasatellites nanoviruses dicots. Alphasatellite...
Endogenous viral sequences are essentially 'fossil records' that can sometimes reveal the genomic features of long extinct virus species.Although numerous known instances exist single-stranded DNA (ssDNA) genomes becoming stably integrated within bacteria and animals, there remain very few examples such integration events in plants.The best studied these those which yielded geminivirus-related elements found nuclear various Nicotiana other ssDNA virus-like included draft plant species, it is...
Several endogenous viral elements (EVEs) have been identified in plant genomes, including pararetroviruses (EPRVs). Here, we report the first characterization of EPRV sequences genome African yam Dioscorea cayenensis-rotundata complex. We propose that these should be termed 'endogenous bacilliform viruses' (eDBVs). Molecular eDBVs shows they constitute originating from various parts badnavirus resulting a mosaic structure is typical most EPRVs characterized to date. Using complementary...
Abstract Badnaviruses are double‐stranded DNA pararetroviruses of the family Caulimoviridae . Badnaviral sequences found in banana distributed over three main clades genus Badnavirus and exhibit wide genetic diversity. Interestingly, nuclear genome many plants, including banana, is invaded by numerous badnaviral although badnaviruses do not require an integration step to replicate, unlike animal retroviruses. Here, we confirm that streak viruses (BSVs) restricted 1 3. We also show only BSVs...
Alfalfa leaf curl virus (ALCV), which causes severe disease symptoms in alfalfa (Medicago sativa L.) and is transmitted by the widespread aphid species, Aphis craccivora Koch, has been found throughout Mediterranean basin as well Iran Argentina. Here we reconstruct evolutionary history of ALCV attempt to determine whether recent discovery detection attributable either past diagnostic biases or emergence global spread over few years. One hundred twenty complete genome sequences recovered from...
The family Geminiviridae comprises a large group of plant ssDNA viruses with geminate particles that are classified in nine genera, including the newly established Capulavirus
Banana streak viruses are among the most widely distributed of banana and responsible for disease. Natural field spread occurs by either mealybugs or use infected planting material, such as suckers. pararetroviruses belonging to genus Badnavirus, in family Caulimoviridae. Like all members Badnavirus genus, they have bacilliform virions, 30 x 150 nm size a circular dsDNA genome 7.4kbp. Fifteen years ago, an increasing number outbreaks disease were reported worldwide. Many occured breeding...
Abstract The increase in human-mediated introduction of plant species to new regions has resulted a rise invasive exotic (IEPS) that had significant effects on biodiversity and ecosystem processes. One commonly accepted mechanism invasions is proposed by the enemy release hypothesis (ERH), which states IEPS free from their native herbivores natural enemies environments can outcompete indigenous become invasive. We here propose virome (VRH) as virus-centered variant conventional ERH only...

In spring 2022, 40 leaf samples of saffron plants harboring a wide variety symptoms, including curling, yellowing, mosaic, dwarfing and malformation were collected from three Khorasan provinces in Iran. These processed using the virion-associated nucleic acid-based metagenomics approach (Moubset et al., 2022). Noteworthy, 147 contigs with size >500 bp distributed among 35 multiple symptomatic patterns (curling, malformation) shared >90% nucleotide identity saffron-associated mastrevirus 1...
