| molecular characterization of squash leaf curl yunnan virus, a new begomovirus and evidence for recombination. | virus isolate y23v, obtained from squash showing leaf curl symptoms in yunnan, china, was readily differentiated from four studied chinese begomovirus isolates in reactions with a set of monoclonal antibodies raised against begomoviruses. the complete nucleotide sequence (2714 nts) of the dna-a-like molecule of y23v was determined. the dna-a of y23v is most closely related to that of tomato yellow leaf curl thailand virus-[1] (tylcthv-[1]) (84% sequence identity). however, the ac1 and ac4 gene o ... | 2003 | 14551824 |
