Molecular characterization of a new begomovirus infecting a leguminous weed Rhynchosia minima in India
Virus Genes 42 (3), 407-414
Abstract: A begomovirus associated with yellow mosaic disease in Rhynchosia minima, a common weed was cloned and sequenced. The virus has a bipartite genome, of which DNA-A is 2727 nucleotide length, and DNA-B 2679 nucleotides, and has a typical Old World bipartite begomovirus genome organization. Sequence comparison to all other begomovirus sequences available in the database shows the virus isolated from R. minima to be distinct. Maximum identity of 84% was seen with an isolate of Velvet bean severe mosaic virus-(India: Lucknow:2009) VBSMV-(IN:Luc:09) (GeneBank Accession No. FN543425), while less than 73% identity was observed with any other legumovirus. The molecular data show that the virus identified here is a new species in the genus Begomovirus for which the name Rhynchosia yellow mosaic India virus is proposed.
