Identification of Begomoviruses Infecting Crops and Weeds in Belize.
Plants including pepper, red kidney bean, squash, string bean and tomato, as well as weeds with viral symptoms were collected from five districts in Belize over a three year period with the aim of determining the diversity of the begomoviruses present. Sixty five percent of the samples screened via DNA hybridization produced signals indicative of begomovirus infection. Subsequent PCR amplificat...
متن کاملGenetic diversity and phylogeography of begomoviruses infecting legumes in Pakistan.
Grain legumes are an important source of dietary protein across southern Asia, but they suffer extensive losses due to several viruses that are members of the genus Begomovirus (family Geminiviridae), which are collectively known as legume yellow mosaic viruses (LYMVs). Despite their economic importance, little attention has been paid to LYMVs in Pakistan and only partial sequences of virus iso...
متن کاملConservation and Dispersion of Genes Conferring Resistance to Tomato Begomoviruses between Tomato and Pepper Genomes
In the present climate change scenario, controlling plant disease through exploitation of host plant resistance could contribute toward the sustainable crop production and global food security. In this respect, the identification of new sources of resistance and utilization of genetic diversity within the species may help in the generation of cultivars with improved disease resistance. Begomovi...

Rojas, A. 2004. A complex of Begomoviruses affecting tomato crops in Nicaragua. Doctor’s dissertation ISSN 1401-6249, ISBN 91-576-6772-1 Diseases caused by begomoviruses (family Geminiviridae, genus Begomovirus) constitute a serious constraint to vegetable production in Nicaragua as they are associated with large economical losses. This thesis was done in an effort to identify and characterize ...
متن کاملPrint-Capture PCR for Detection of Tomato Begomoviruses from Plants and Whiteflies
Print-capture (PC) Polymerase chain reaction (PCR) was evaluated as a novel detection method of plant viruses. Tomato (Lycopersicon esculentum) plants infected with begomovirus (fam. Geminiviridae, gen. Begomovirus) and viruliferous whiteflies were used to study the efficiency of the method. Print-capturing steps were carried out using non-charged nylon membrane or filter paper as the solid sup...
