摘要: AbstractThe 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 conserved 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.
