distribution and diversity of geminiviruses in trinidad and tobago.abstract seven crop and eight weed species from 12 agricultural locations in trinidad and tobago were assayed for the presence of whitefly-transmitted geminiviruses (wtgs) by using dot blot hybridization and polymerase chain reaction (pcr) amplification of the n-terminal coat protein sequence with degenerate primers. the amplified fragments were cloned and analyzed by restriction enzyme digestion to determine fragment length polymorphism among the cloned fragments. representative clones were the ...199818944827
molecular characterization and experimental host range of an isolate of macroptilium golden mosaic virus that infects wissadula amplissima in jamaica.partial genome sequences for the tentative begomovirus macroptilium golden mosaic virus (mgmv) have been previously reported and were originally obtained for an isolate that infected macroptilium lathyroides in jamaica. in this study, we pcr-amplified, cloned and determined the sequence for the complete genome of isolates of mgmv that we found infecting wissadula amplissima collected from august town and spanish town, jamaica. sequence analysis confirmed that mgmv is a distinct begomovirus speci ...201020347895
