| tomato yellow leaf curl thailand virus-[y72] from yunnan is a monopartite begomovirus associated with dnabeta. | previous studies have shown that isolates of tomato yellow leaf curl thailand virus (tylcthv) originated from thailand are bipartite begomoviruses, while all the seven tylcthv isolates found in china are associated with dnabeta molecules. in this study, infectious clones of tylcthv isolate y72 (tylcthv-[y72]) and its dnabeta were constructed to verify the bipartite or monopartite nature of tylcthv. agroinoculation showed that tylcthv-[y72] alone was able to induce significant symptoms in nicotia ... | 2009 | 19165588 |
| 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 |
| molecular variation of satellite dna beta molecules associated with malvastrum yellow vein virus and their role in pathogenicity. | previous studies have found that the diversity of begomovirus-associated dna beta satellites is related to host and geographical origin. in this study, we have cloned and sequenced 20 different isolates of dna beta molecules associated with malvastrum yellow vein virus (myvv) isolated from malvastrum coromandelianum plants in different geographical locations of yunnan province, china. analyses of their molecular variation indicate that the satellites are clustered together according to their geo ... | 2008 | 18245261 |
