- Abstract
To characterize their virome, double stranded RNAs extracted from scrapings of two Iranian grapevine varieties held in the Vassal-Montpellier Grapevine Biological Resources Center were analysed by high-throughput sequencing. In addition to several well-known grapevine viruses, divergent isolates of the newly described grapevine Kizil Sapak virus were identified in both accessions. Four complete genome sequences were determined, as well as two additional partial sequences (1,580 and 3,849 nucleotides long). These genomic sequences highlight the molecular diversity of this poorly known virus. In view of the absence of amplification of the GKSV isolates characterized here using the published primer pair, novel degenerate, polyvalent primers were designed, providing a more robust diagnosis.
