| molecular characterization of a distinct begomovirus infecting tobacco in yunnan, china. | 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 w ... | 2001 | 11676420 |
