Occurrence and molecular characterization of Tomato common mosaic virus (ToCmMV) in tomato fields in Espírito Santo state, Brazil
Tropical Plant Pathology 41 (1), 62-66
Abstract: Here, we report for the first time the complete molecular characterization of a begomovirus infecting tomato crops in Espírito Santo state, Brazil. Based on the analysis of partial nucleotide sequences of isolates obtained from 20 samples, collected from 2007 to 2011, all isolates were preliminary classified as Tomato commom mosaic virus (ToCmMV). Complete nucleotide sequences of the DNA-A and DNA-B components of one isolate were determined. The DNA-A sequence shares 97.5 % identity with that of ToCmMV-[BR:Coi22:07], thus confirming it to be an isolate of ToCmMV. In addition, recombination analysis showed that this ToCmMV isolate probably evolved from an inter-species recombination event and likely contributed to the emergence of the weed-infecting begomovirus, Sida yellow leaf curl virus (SiYLCV).
