Response of tomato (Solanum L. section Lycopersicon Mill.) germplasm to begomov...
Aguilera, Jorge González; Hurtado, Francisco Dueñas; Almeida, Victor de Souza; Tavares, Sheila S.; Nick, Carlos; Soares, Marcelo OliveiraNinety-five tomato accessions belonging to the Vegetable Crops Germplasm Bank of the Federal University of Viçosa (BGH-UFV) were evaluated in a protected environment (biolistic inoculation under greenhouse conditions) and in the field (natural infection) for resistance to bipartite begomoviruses present in Brazil. Plants were assessed by the visual evaluation of symptoms, and viral infection was confirmed by no...
Contrasting genetic structure between two begomoviruses infecting the same legu...
Xavier, César Augusto Diniz; Pereira, Hermano Monteiro de Barros; Lima, Gaus Silvestre de Andrade; Assunção, Iraı́ldes PereiraBegomoviruses are whitefly-transmitted, ssDNA plant viruses and are among the most damaging pathogens causing epidemics in economically important crops worldwide. Wild/non-cultivated plants play a crucial epidemiological role, acting as begomovirus reservoirs and as ‘mixing vessels’ where recombination can occur. Previous work suggests a higher degree of genetic variability in begomovirus populations from non-c...

Ramos Sobrinho, RobertoConselho Nacional de Desenvolvimento Científico e Tecnológico; Vírus pertencentes à família Geminiviridae possuem genoma circular de fita simples e infectam uma ampla gama de hospedeiros causando perdas significativas, principalmente em países tropicais e subtropicais. A família é dividida em sete gêneros (Begomovirus, Becurtovirus, Curtovirus, Eragrovirus, Mastrevirus, Topocuvirus e Turncurtovirus) de acordo c...
