摘要: Malvastrum coromandelianum is a common weed plant frequently found around agricultural fields. Three virus isolates (Y249, Y278 and Y281) were obtained from M. coromandelianum with yellow vein symptoms in Honghe and Baoshan, Yunnan Province, China. Specific 500bp products were amplified from total DNA extracts using universal primers for members of the genus Begomovirus. The complete viral genome sequences of both Y278 and Y281 were determined to be 2743 nucleotides, and that of Y249 was determined to be 2740 nucleotides. Sequence alignments and phylogenetic analyses support the proposal of creating new species in the genus Begomovirus, for which the name malvastrum yellow vein Baoshan virus (MaYVBsV) is proposed for Y278 and Y281, and malvastrum yellow vein Honghe virus (MaYVHhV) is proposed for Y249.
