MJ: The complete genome sequence of two isolates of Southern rice black-streaked dwarf virus, a new member of the Genus Fijivirus

The nucleotide sequences of genomic segments S1–S8 and S1–S6, respectively, of the Hainan (HN) and Guangdong (GD) isolates of a rice-infecting fijivirus were determined, completing the genome sequences of these isolates. The isolates were most closely related to Rice black-streaked dwarf virus (RBSDV): S1, S2 and S10 were most conserved with identities of 78.5–79.2% nt (83.4–89.0 % aa) while S5 and S6 were the least con-served with 70.6–71.6 % nt (63.1–69.9 % aa) identity. Whole genome comparisons and phylogenetic analyses supported suggestions that the isolates represent a new species within the genus Fijivirus, family Reoviridae. Of the two names previously suggested for this virus, Southern rice black-streaked dwarf virus is preferred
