Macroptilium lathyroides (L) is a weed that is widely distributed in Cuba. Frequently, leaves show bright yellow mosaic symptoms, which suggest the incidence of a viral disease. Since begomovirus occurrence in Macroptilium lathyroides has been previously reported in other islands of the Caribbean
Genetic diversity among geminiviruses associated with three common weeds in Jamaica was studied using digoxigenin-labeled geminiviral DNA probes, polymerase chain reaction with degenerate primers for DNA-A and DNA-B, nucleic acid sequencing, and derived amino acid sequences. Geminiviruses with
The leguminous weed Macroptilium lathyroides is considered a potential host of the Bean golden yellow mosaic virus (BGYMV; BGMV = Mesoamerican isolates). To determine if M. lathyroides could be a host for BGYMV, an infectivity cycle was established between this weed and Phaseolus vulgaris. Virus
In September 1998, tomato plants in Barbados exhibited symptoms of severe leaf curling without marginal chlorosis. These symptoms were often associated with an increase in whitefly (Bemisia tabaci) populations. DNA was extracted from leaf tissue from symptomatic tomato plants. Polymerase chain
