Varying genetic diversity of Papaya ringspot virus isolates from two time-separated outbreaks in Jamaica and Venezuela

Varying genetic diversity of Papaya ringspot virus isolates from two time-separated outbreaks in... Coat protein sequences of 22 Papaya ringspot virus isolates collected from different locations in Jamaica and Venezuela in 1999 and 2004, respectively, were determined and compared with sequences of isolates from earlier epidemics in 1990 and 1993. Jamaican isolates collected in 1999 exhibited nucleotide sequence identities between 98 and 100% but shared lower identities of 92.2% with an isolate collected in 1990. Isolates from the 2004 epidemic in Venezuela exhibited more heterogeneity, with identities between 88.7 and 98.8%. However, isolates collected in 1993 were more closely related (97.7%). The viral populations of the two countries are genetically different and appear to be changing at different rates; presumably driven by introductions, movement of plant materials, geographical isolation, and disease management practices. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
