The complete genome of a bipartite begomovirus (genus Begomovirus, family Geminiviridae) infecting Jacquemontia sp. (Convolvulaceae) in Venezuela has been cloned and sequenced. Sequence comparison and phylogenetic analysis have shown that it represents an isolate of a novel species with closest relatives being two New World bipartite begomoviruses that infect Convolvulaceae, Jacquemontia mosaic Yucatan virus and Merremia mosaic virus. The DNA-As of these begomoviruses, however, share only 77.0-78.4 % nucleotide sequence identity with the DNA-A of the isolate described here, for which a recombinant origin is suggested. Based on the symptoms observed in the field, the name Jacquemontia yellow mosaic virus (JacYMV) is proposed for this novel bipartite begomovirus.
