| 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 |
| trans-replication of, and competition between, dna beta satellites in plants inoculated with tomato yellow leaf curl china virus and tobacco curly shoot virus. | tomato yellow leaf curl china virus (tylccnv) y10 isolate (y10) and tobacco curly shoot virus (tbcsv) y35 isolate (y35), both obtained from yunnan province, were each found to be associated with a distinct species of satellite dna (dna beta). here, we demonstrate that both y10 dna beta (y10beta) and y35 dna beta (y35beta) were stably trans-replicated by the noncognate begomovirus, although the noncognate dna beta accumulated in plants at a lower level than did the cognate dna beta. in nicotiana ... | 2009 | 19453231 |
