| Abstract: | Nucleotide sequences of the three distinct Tomato yellow leaf curl Thailand virus (TYLCTHV) strains (CM, NK, SK) were analyzed for recombination events. Recombination detection program analyses and a sequence alignment survey provided evidence of recombination between AC1 sequences of TYLCV, TYLCTHV-[MM], and TYLCTHV-[NK] as major parents and of ToLCLV, ToLCTWV, and TYLCTHV-[SK] as minor parents of TYLCTHV-[NK], -[SK], -[CM], respectively. The results further support the notion that interspecies recombination may play a significant role in geminivirus diversity and their emergence as important pathogens. |
