| multiple infection, recombination and genome relationships among begomovirus isolates found in cotton and other plants in pakistan. | begomoviruses occur in many plant species in pakistan and are associated with an epidemic of cotton leaf curl disease that has developed since 1985. pcr analysis with primer pairs specific for each of four already sequenced types of dna-a of cotton leaf curl virus (clcuv-pk types a, 26, 72b and 804a), or for okra yellow vein mosaic virus (oyvmv), indicated that many individual naturally infected plants of cotton and other malvaceous species contained two or three begomovirus sequences. similarly ... | 2000 | 10859391 |
| begomovirus characterization, and development of phenotypic and dna-based diagnostics for screening of okra genotype resistance against bhendi yellow vein mosaic virus. | the leaf sample from okra plants showing the yellow vein mosaic disease symptoms was collected in karnataka state, india. the genome of the virus was amplified, cloned and sequenced. sequence analysis revealed that the viral genome (gu112065) is 2,741 bp in length and genome is similar to that of monopartite begomoviruses originating from the old world, with seven conserved orfs. further nucleotide (nts) sequence comparisons showed that the genome has the highest sequence identities of 96.1 % wi ... | 2013 | 28324417 |
| genetic variability of begomoviruses associated with cotton leaf curl disease originating from india. | cotton leaf curl disease (clcud) causing viruses belong to the begomovirus genus of the family geminiviridae. most begomoviruses are bipartite with two molecules of circular single stranded dna (a and b) encapsidated in icosahedral geminate particles. however, the begomoviruses associated with clcud have dna-beta instead of dna-b. in this communication we report the complete genomic sequence of dna-a component of two clcud-causing begomoviruses, cotton leaf curl kokhran virus-dabawali (clcukv-da ... | 2004 | 15669112 |
