| characterization and distribution of tomato yellow margin leaf curl virus, a begomovirus from venezuela. | a begomovirus causing mottling and leaf deformation in tomato from the state of mérida was cloned and sequenced. the virus has a bipartite genome comprised of a dna-a (2,572 nucleotides) and a dna-b (2,543 nucleotides) with a genome organization typical of new world begomoviruses. both components share a common region of 115 nucleotides with 98 % sequence identity. phylogenetic analysis indicated that while no virus sequences were closely related, the a component was distantly related to those o ... | 2013 | 23064695 |
