| molecular characterization of a distinct bipartite begomovirus species infecting tomato in india. | a distinct bipartite begomovirus was found associated with tomato plants showing yellowing, curling, and crumpling of the leaves, in a sub-temperate region in india. the complete dna-a and dna-b components were amplified through rolling circle amplification (rca) using phi-29 dna polymerase and characterized. the dna-a of the isolate was comprised of 2,756 nucleotides, encoding six open reading frames (orfs) and dna-b that of 2,725 nucleotides, encoding two orfs. genome organization of the isola ... | 2008 | 18792773 |
