Begomovirus diversity in tomato crops and weeds in Ecuador and the detection of...
Paz-Carrasco, Lenin C.; Castillo-Urquiza, Gloria P.; Lima, Alison T. M.; Xavier, Cesar A. D.; Vivas-Vivas, Leticia M.; Mizubuti, Eduardo S. G.Viral diseases caused by begomoviruses are of economic importance due to their adverse effects on the production of tropical and subtropical crops. In Ecuador, despite reports of significant infestations of Bemisia tabaci in the late 1990s, only very recently has a begomovirus, tomato leaf deformation virus (ToLDeV, also present in Peru), been reported in tomato. ToLDeV is the first monopartite begomovirus disc...
Brazilian begomovirus populations are highly recombinant, rapidly evolving, and...

D.; Hora-Júnior, Braz T.The incidence of begomovirus infections in crop plants sharply increased in Brazil during the 1990s following the introduction of the invasive B biotype of the whitefly vector, Bemisia tabaci. It is believed that this biotype transmitted begomoviruses from noncultivated plants to crop species with greater efficiency than indigenous B. tabaci biotypes. Either through rapid host adap- tation or selection pressure...
