Deep sequencing analysis of viral short RNAs from an infected Pinot Noir grapevine

Abstract

Virus-derived short interfering RNAs (vsiRNAs) isolated from grapevine V. vinifera Pinot Noir clone ENTAV115 were analyzed by high-throughput sequencing using the Illumina Solexa platform. We identified andcharacterized vsiRNAs derived from grapevine field plants naturally infected with different viruses belongingto the genera Foveavirus, Maculavirus, Marafivirus and Nepovirus. These vsiRNAs were mainly of 21 and 22nucleotides (nt) in size and were discontinuously distributed throughout Grapevine rupestris stem-pittingassociated virus (GRSPaV) and Grapevine fleck virus (GFkV) genomic RNAs. Among the studied viruses, GRSPaVand GFkV vsiRNAs had a 52 terminal nucleotide bias, which differed from that described for experimental viralinfections in Arabidopsis thaliana. VsiRNAs were found to originate from both genomic and antigenomicGRSPaV RNA strands, whereas with the grapevine tymoviruses GFkV and Grapevine Red Globe associatedvirus (GRGV), the large majority derived from the antigenomic viral strand, a feature never observed in otherplant–virus interactions.
