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 کاملInfectivity, pseudorecombination and mutagenesis of Kenyan cassava mosaic begomoviruses.
Cloned DNA-A and DNA-B components of Kenyan isolates of East African cassava mosaic virus (EACMV, EACMV-UG and EACMV-KE2), East African cassava mosaic Kenya virus (EACMKV) and East African cassava mosaic Zanzibar virus (EACMZV) are shown to be infectious in cassava. EACMV and EACMKV genomic components have the same iteron sequence (GGGGG) and can form viable pseudorecombinants, while EACMZV com...
متن کاملThe Diversity of Cassava Mosaic Begomoviruses in Africa
Cassava mosaic disease (CMD) is the most widespread and economically important disease of cassava (Manihot esculenta Crantz) in tropical Africa. A disease of cassava was first described in East Africa in the nineteenth century (Warburg, 1894) and cassava mosaic, as it came to be called, was subsequently reported as spreading throughout the cassava-growing areas of Central and West Africa (Calve...
متن کاملThe occurrence and distribution of fluoride in groundwaters of Kenya.
Water samples from 1286 boreholes from different parts of Kenya were analysed for their fluoride concentrations. The majority of the samples (61.4%) had fluoride ion concentrations above 1.0 parts per million, whilst 19.5% had above 5.0 ppm. Excess levels of fluoride were found to occur in most parts of the country, especially in the Nairobi, Rift Valley, Eastern and Central Provinces which con...
