| tomato leaf curl virus from bangalore (tolcv-ban4): sequence comparison with indian tolcv isolates, detection in plants and insects, and vector relationships. | tomato leaf curl virus (tolcv) is a whitefly (bemisia tabaci) transmitted geminivirus (family geminiviridae, genus begomovirus) causing a destructive disease of tomato in many regions of india, east asia and australia. while tolcv isolates from australia and taiwan have a single genomic component (designated dna-a), those from northern india have two components (dna-a and dna-b). the tolcv isolates from southern india (bangalore) previously cloned seem to have a dna-a-like monopartite genome. we ... | 2000 | 11003471 |
| molecular identification of a new begomovirus associated with yellow mosaic disease of jatropha gossypifolia in india. | yellow mosaic disease was observed on jatropha gossypifolia plants growing in kathaupahadi, madhya pradesh, india, and whiteflies (bemisia tabaci) were found in the vicinity. association of a new begomovirus with yellow mosaic disease of j. gossypifolia has been detected by pcr using begomovirus dna-a-specific primers. the complete dna-a genome (~2.7 kb) of this virus isolate was amplified by rolling-circle amplification (rca) followed by digestion with bam hi. the ~2.7-kb amplicons was cloned a ... | 2011 | 21971870 |
| evidence for recombination among the tomato leaf curl virus strains/species from bangalore, india. | tomato leaf curl virus (tolcv) belongs to the begomovirus genus of the family geminiviridae. these viruses have circular single stranded dna molecules as their genome encapsidated in icosahedral geminate particles. generally the begomoviruses are bipartite with respect to their genomic composition. tolcv from south india is unique in that only dna a component has been isolated and sequenced thus far and there is no evidence for the presence of dna b component. in this communication we report the ... | 2002 | 11892687 |
