Genomic characterization of soybean blotchy mosaic virus, a cytorhabdovirus from South Africa.

Samples showing blotchy mottle symptoms were collected from soybeans in North-West province, South Africa. The assembly of high-throughput sequencing data from three samples yielded contigs of 13,426 to 13,435nt, which represent the first complete genome sequences of soybean blotchy mosaic virus (SbBMV). SbBMV shows a typical cytorhabdovirus gene organization (3′-N-P-P3-M-G-L-5'), with each putative gene product being most similar, but with only 49.1-71.1% sequence identity, to those of cucurbit cytorhabdovirus 1. Given the species demarcation thresholds for rhabdoviruses, SbBMV is thus a distinct member of the genus Cytorhabdovirus. [ABSTRACT FROM AUTHOR]
