| 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 |
| 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 |
