Widespread occurrence of tomato geminiviruses in Brazil, associated with the new biotype of the whitefly vector
Plant Disease 82 (7), 830-830
Abstract: Since 1994, tomato plants grown in the Federal District of Brazil and in the states of Minas Gerais and Pernambuco were observed with symptoms of yellow mosaic, severe leaf distortion, down-cupping, and epinasty. Incidence of virus-like symptoms was close to 100% in some fields and whitefly (B biotype of Bemisia tabaci) infestation was high in all fields sampled. The presence of at least six different geminiviruses was demonstrated in the symptomatic plants using PCR analysis and nucleotide sequencing. The viruses were most closely related to tomato golden mosaic virus, bean golden mosaic virus from Brazil, and tomato yellow vein streak virus, but sequence homologies were less than 80% for the fragments compared.
