Development of new tools to study Beet Virus Q

Beet virus Q (BVQ), often detected in sugar beet roots infected by Beet necrotic yellow vein virus (BNYVV), the causal agent of the rhizomania syndrome, and in co-infection with Beet soil-borne virus (BSBV), is still poorly characterized. In order to investigate the functioning and potential pathogenicity of BVQ in planta, full-length cDNA clones were developed for the three genomic RNAs. Transcripts from BVQ constructs were shown to be infectious and able to produce clear symptoms on both Chenopodium quinoa and Beta macrocarpa
