| first report of a complete genome sequence for a begomovirus infecting jatropha gossypifolia in the americas. | jatropha gossypifolia is a weed that is commonly found with yellow mosaic symptoms growing along the roadside and in close proximity to cultivated crops in many farming communities in jamaica. for the first time, the complete genome sequence of a new begomovirus, designated jatropha mosaic virus-[jamaica:spanish town:2004] (jmv-[jm:st:04]), was determined from field-infected j. gossypifolia in the western hemisphere. dna-a nucleotide sequence comparisons showed closest identity (84 %) to two tob ... | 2014 | 24872185 |
| molecular and biological characterization of distinct strains of jatropha mosaic virus from the dominican republic reveal a potential to infect crop plants. | in the dominican republic (do), jatropha plants with yellow mosaic symptoms are commonly observed in and around fields of various crop plants. complete nucleotide sequences of dna-a and dna-b components of four bipartite begomovirus isolates associated with symptomatic jatropha plants collected from three geographical locations in the do were determined. sequence comparisons revealed highest identities (91 to 92%) with the dna-a component of an isolate of jatropha mosaic virus (jmv) from jamaica ... | 2015 | 25163012 |
| the complete genome sequence of new world jatropha mosaic virus. | full-length sequences of a bipartite begomovirus were obtained from a plant of jatropha multifida in florida showing symptoms of foliar mosaic, distortion and necrosis. sequences of four clones each of a dna-a and dna-b were obtained, which showed very low sequence diversity among themselves. the clones were infectious when biolistically inoculated to j. multifida, phaseolus vulgaris and nicotiana tabacum, but not to j. curcas. the dna-a sequences had less than 89 % pairwise identity scores with ... | 2014 | 25091738 |
| metabolic and histopathological alterations of jatropha mosaic begomovirus-infected jatropha curcas l. by hr-mas nmr spectroscopy and magnetic resonance imaging. | alterations in the anatomical structures, sap translocation and metabolic profiles in jatropha curcas l. (euphorbiaceae), infected with jatropha mosaic virus (jmv) have been investigated using mri and hr-mas nmr spectroscopy. the contrast of mri images distinguishes abnormalities in anatomical structures of infected and healthy stem. the hr-mas nmr spectroscopic analysis indicated that viral infection significantly affected the plant metabolism. higher accumulation of tca cycle intermediates, su ... | 2010 | 20372923 |
