Abstract:
:Virus isolate Y3V, obtained from tobacco showing leaf curl symptoms in Yunnan, China, had particles with the size and morphology typical of geminiviruses. In reactions with a set of monoclonal antibodies raised against begomoviruses, Y3V was readily differentiated from two previously studied Chinese Begomovirus isolates. The complete nucleotide sequence of a DNA-A-like molecule of Y3V was determined; it comprises 2744 nucleotides and has a typical Begomovirus genome organization. When compared with the DNA-A sequences of other begomoviruses, the total DNA-A of Y3V was most closely related to that of Ageratum yellow vein virus (AYVV) (85% sequence identity), but the Y3V intergenic region differed greatly from those of the other sequences (maximum 70% identity). In contrast, the deduced coat protein of Y3V is most like that of Tomato yellow leaf curl Thailand virus-[1] (TYLCTHV-[1]) (92% amino acid sequence identity). The molecular data show that the Yunnan isolate of Tobacco leaf curl virus is a distinct Begomovirus species, for which the name Tobacco leaf curl Yunnan virus (TLCYnV) is proposed.
