The molecular and biological characterization of a begomovirus infecting the common weed Macroptilium lathyroides from Jamaica are reported. The virus showed 92% sequence identity to an isolate of Macroptilium yellow mosaic virus (MaYMV) from Cuba, but was distinct from the two other begomoviruses isolated from M. lathyroides , namely Macroptilium yellow mosaic Florida virus (80% identity) and Macroptilium mosaic Puerto Rico virus (68% identity). Hence, the Jamaican begomovirus was considered an isolate of MaYMV and called Macroptilium yellow mosaic virus ‐[Jamaica] (MaYMV‐[JM]). In infectivity studies using cloned DNA‐A and DNA‐B genomic components, MaYMV‐[JM] infected red kidney bean ( Phaseolus vulgaris ) and produced mild symptoms in Scotch Bonnet pepper ( Capsicum chinense ), but did not infect cabbage ( Brassica oleracea ). This information has implications for the development of strategies to control begomovirus diseases in Jamaica and elsewhere.
