Conteúdo: | The whitefly Bemisia tabaci is an agricultural pest causing large economic losses worldwide. We analysed the genomic sequence of a new viral member of the family Dicistroviridae identified by high-throughput sequencing of total RNA extracted from whiteflies. The virus, tentatively named Bemisia-associated dicistrovirus 2 (BaDV-2), has a genome of 8012 nucleotides with a polyadenylated 3&#8242; end. In contrast to typical dicistroviruses, BaDV-2 has a genome containing three open reading frames (ORFs) encoding predicted proteins of 1078 (ORF1a), 481 (ORF1b) and 834 (ORF2) amino acids, which correspond to replicase A (containing helicase and cysteine protease domains), replicase B (a domain of an RNA-dependent RNA polymerase - RdRP) and capsid proteins, respectively.
