complete nucleotide sequence of iranian tomato yellow leaf curl virus isolate: further evidence for natural recombination amongst begomoviruses. brief report.	complete nucleotide sequence of the iranian strain of tomato yellow leaf curl virus (tylcv-ir) was determined and compared with some begomoviruses. the complete sequence of tylcv-ir clustered together with tylcv and tylcv-mid from israel. a similar relationship holds when the deduced amino acid sequences of v1, v2, c2 and c3 and nucleotide sequences of ir, and rir were compared. in contrast, phylogenetic analyses of amino acid sequences of c4, c1, and nucleotide sequences of lir revealed that ty ...	2004	15221543
tomato leaf curl gujarat virus, a new begomovirus species causing a severe leaf curl disease of tomato in varanasi, india.	abstract the biological and molecular properties of tomato leaf curl gujarat virus from varanasi, india (tolcgv-[var]) were characterized. tolcgv-[var] could be transmitted by grafting and through whitefly transmission in a persistent manner. the full-length genome of dna-a and dna-b of tolcgv-[var] was cloned in puc18. sequence analysis revealed that dna-a (ay190290) is 2,757 bp and dna-b (ay190291) is 2,688 bp in length. tolcgv-[var] could infect and cause symptoms in tomato, pepper, nicotiana ...	2003	18943612
tomato leaf curl karnataka virus from bangalore, india, appears to be a recombinant begomovirus.	abstract the genome of tomato leaf curl virus (tolcv) from bangalore, india, a whitefly-transmitted geminivirus, was cloned (pind9) and sequenced. the circular dna of 2,759 nucleotides (u38239) is organized similarly to that of other begomoviruses with monopartite genomes. comparison of the nucleotide sequence of pind9 with other tomato-associated begomoviruses from india (tomato leaf curl bangalore virus [tolcbv, z48182]) and tomato leaf curl new delhi virus-severe (tolcndv-svr, u15015) showed ...	2002	18944261
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
cotton leaf curl multan betasatellite as a plant gene delivery vector trans-activated by taxonomically diverse geminiviruses.	cotton leaf curl multan betasatellite (clcumb) replicates in tobacco, tomato and datura plants in the presence of the helper viruses tomato leaf curl virus-australia, iranian isolates of tomato yellow leaf curl virus, tomato leaf curl karnataka virus, and beet severe curly top virus (bsctv). infectious recombinant clcumb constructs were made in which segments of either the camv 35s or the petunia chsa promoter replaced the clcumb βc1 orf, and these were designated pbinβδc1-35s and pbinβδc1-chsa, ...	2012	22476203
a geminivirus-satellite complex is associated with leaf deformity of mentha (mint) plants in punjab.	a widespread leaf deformity disease of mentha (mint), accompanied by whiteflies, the vectors of begomoviruses, was observed in punjab in the last few years. the presence of begomovirus was indicated by dna dot-blot analysis using the conserved coat protein and replication-associated protein genes of another begomovirus, sri lankan cassava mosaic virus (slcmv). a dna fragment (2.0 kb), representing a partial genomic dna of a begomovirus, amplified from the symptomatic mentha leaves was used to de ...	2011	23637488
