First report of tomato mottle geminivirus in Mexico
Geminiviruses transmitted by Bemisia tabaci (EPPO A2 quarantine pest) are a major constraint on tomato production in Mexico. In Yucatan State, where serious losses can be observed, particularly on late season tomato crops, studies were carried out to characterize the geminiviruses present. Four tomato plants showing typical symptoms of geminivirus infection (stunting, leaf mottling, leaf deformation) were collected in a single field from Yucatan, in 1996. The occurrence of tomato mottle geminivirus (EPPO A1 quarantine pest) was demonstrated by molecular analysis. In one sample, another bipartite geminivirus was also detected in mixed infection with tomato mottle geminivirus. This is the first report of tomato mottle geminivirus in Mexico.
