摘要
The complete genome sequence of a cucurbit-infecting fabavirus was determined. Sequence analysis revealed that it had a genomic organization typical of fabaviruses, with genome segment sizes of 5870 nt (RNA-1) and 3294 nt (RNA-2). It shared CP and Pro-Pol amino acid sequence identities of 52.0–58.9% with those of reported fabaviruses. ELISA and western blots gave no cross-reactions between this cucurbit virus and broad bean wilt viruses 1 and 2. Based on molecular and serological criteria for species demarcation in the genus Fabavirus, the virus represents a distinct species, for which the species name Cucurbit mild mosaic virus (CuMMV) is proposed.
