characterization of dnabeta associated with begomoviruses in china and evidence for co-evolution with their cognate viral dna-a.	eighteen samples of begomoviruses isolated from tobacco, tomato and weed species in yunnan, china were found to be associated with dnabeta molecules, for which the complete nucleotide sequences were found to contain 1333-1355 nt. the 18 dnabeta molecules identified consist of three main types, each associated with a different begomovirus species: 72-99 % nucleotide identity was found within one type, but only 39-57 % identity was found between types. all the dnabeta molecules reported here and e ...	2003	12533720
molecular characterization of tomato-infecting begomoviruses in yunnan, china.	the importance of diseases of tomato caused by begomoviruses is increasing worldwide. here, we report that several begomoviruses are associated with tomato leaf curl disease in yunnan province, china. 14 tomato samples showing leaf curl symptoms were collected in three districts in yunnan, and they fell into four groups according to their reaction with a panel of 16 monoclonal antibodies in tas-elisa. comparison of partial dna-a sequences amplified with degenerate primers confirmed the existence ...	2004	15593415
[genomic characterization of tomato yellow leaf curl china virus and its associated satellite dna infecting tobacco in guangxi].	the virus isolates g102 and g103 were collected from tobacco showing leaf curl symptoms in jingxi, guangxi province. a 0.5kb fragment was obtained by pcr using primers specific to geminivirus genome. the nucleotide sequence identity of the partial dna-a sequence between the two isolates was over 99%. the complete dna-a sequence of g102 was determined to be 2728 nucleotides. comparisons showed that the dna-a of g102 had the highest sequence identity (96.5%) with that of tomato yellow leaf curl ch ...	2006	16933601
trans-replication of, and competition between, dna beta satellites in plants inoculated with tomato yellow leaf curl china virus and tobacco curly shoot virus.	tomato yellow leaf curl china virus (tylccnv) y10 isolate (y10) and tobacco curly shoot virus (tbcsv) y35 isolate (y35), both obtained from yunnan province, were each found to be associated with a distinct species of satellite dna (dna beta). here, we demonstrate that both y10 dna beta (y10beta) and y35 dna beta (y35beta) were stably trans-replicated by the noncognate begomovirus, although the noncognate dna beta accumulated in plants at a lower level than did the cognate dna beta. in nicotiana ...	2009	19453231
characterization of alphasatellites associated with monopartite begomovirus/betasatellite complexes in yunnan, china.	alphasatellites are single-stranded molecules that are associated with monopartite begomovirus/betasatellite complexes.	2010	20678232
a recombinant begomovirus resulting from exchange of the c4 gene.	a begomovirus isolated from malvastrum coromandelianum and tomato originating from yunnan province (china) was shown to be representative of a new begomovirus species, for which the name tomato leaf curl yunnan virus (tlcynv) is proposed. tlcynv has high levels of sequence identity to tomato yellow leaf curl china virus (tylccnv) across the whole genome, except for sequences encompassing the c4 gene. agrobacterium-mediated inoculation showed tlcynv to be highly infectious to a range of plant spe ...	2013	23720217
