摘要

The complete genome sequence of fig leaf mottle-associated virus 2 (FLMaV2), a positive-sense single-stranded RNA virus with a genome length of 16,925 nucleotides, was determined via RT-PCR and rapid amplification of cDNA ends (RACE). Its genome organization resembles those of little cherry virus 2 (LChV2) and yam asymptomatic virus 1 (YaV1), both of which are currently classified as members of the genus Ampelovirus but differ from typical ampeloviruses. Phylogenetic analysis based on amino acid sequences of the RNA-dependent RNA polymerase and coat protein of members of the family Closteroviridae showed that FLMaV2 clustered with LChV2 and YaV1. Because of their unusual genome organization, FLMaV2, LChV2, and YaV1 might represent a distinct genus within the family Closteroviridae.
