UMR BFP - Equipe Virologie. International audience. Over the last decade, many scientific disciplines have been impacted by the dawn of new sequencing techniques (HTS: high throughput sequencing). Plant pathology and more specifically virology have been greatly transformed by this 'metagenomics' paradigm shift. Such tools significantly facilitate disease diagnostics with tremendous sensitivity, providing invaluable information such as an exhaustive list of viruses being present in a sample as well as their relative concentration. In addition, many new plant viruses have been discovered. Using RNAseq technology, in silico reconstruction of complete viral genome sequences is easily attainable. This step is of importance for taxonomy, population structure analyses, phylogeography and viral evolution studies. Here, after assembling 81 new near-complete genome sequences of grapevine rupestris stem pitting-associated virus (GRSPaV), we performed a genome-wide diversity study of this ubiquitous virus of grapevine worldwide.
