Tomato yellow spot virus, a tomato-infecting begomovirus from Brazil with a clo...
Andrade, E. C.; Manhani, G. G.; Alfenas, P. F.; Calegario, R. F.; Fontes, E. P. B.; Zerbini, F. M.Geminiviruses are characterized by a circular, single-stranded DNA genome and twinned icosahedral particles. Begomoviruses (whitefly-transmitted geminiviruses) are a major constraint to crop production worldwide. In Brazil, tomato-infecting begomoviruses emerged as serious pathogens over the last 10 years, due to the introduction of a new biotype of the insect vector. Tomato yellow spot virus (ToYSV) is a newly...
Biological and molecular properties of Tomato rugose mosaic virus (ToRMV), a ne...
Fernandes, J. J.; Carvalho, M. G.; Andrade, E. C.; Brommonschenkel, S. H.; Fontes, E. P. B.; Zerbini, F. M.A viral complex causing golden mosaic and leaf distortion (rugosity) in tomato plants was obtained from viruliferous whiteflies, and named TGV-Ub1. This complex was sap-transmitted from tomato to Nicotiana benthamiana. PCR amplification using universal begomovirus primers yielded two distinct fragments for DNA-A, suggesting that the TGV-Ub1 complex comprised at least two distinct viruses. Clones corresponding t...
