Complete genome sequence of Sikte (Sitke) waterborne virus, a member of the genus Tombusvirus

The 4704-nt genome sequence of Sikte waterborne virus (SWV), determined by fragmented and primer ligated dsRNA sequencing and by direct Sanger sequencing, is linear, nonsegmented and has the five ORFs of other tombusviruses. The 5′ and 3′ untranslated regions (UTRs) are 150 and 335 nt long, respectively. Phylogenetic analysis of the coat protein revealed that SWV is related to CymRSV and PNSV, but that of the SWV replicase protein, the p92 readthrough protein, indicated a close relationship to CNV. These phylogenetic analyses suggest the occurrence of recombination events in SWV, as reported previously for other tombusviruses.
