tomato chlorosis virus (tocv) is a species in the genus crinivirus, transmitted by bemisia tabaci biotype b, first detected in brazil in 2006 in the county of sumaré, state of s？o paulo. during the period from 2007 to 2010, rt-pcr analyses followed by nested-pcr with specific primers for tocv detection, and sequencing of the amplicons, confirmed the presence of this virus in samples of symptomatic tomato plants (solanum lycopersicum) from crops in counties in the states of bahia (ba), espírito santo (es), goiás (go), minas gerais (mg), and rio de janeiro (rj). this is the first tocv report for the states of ba, es, go, mg, and rj, suggesting that this virus is widely disseminated in brazil.
