| molecular characterization and phylogenetic relationships of two new bipartite begomovirus infecting malvaceous plants in yucatan, mexico. | sida acuta and corchorus siliquosus plants showing yellow mosaic and yellow vein symptoms, respectively, were collected in the yucatan peninsula, mexico. total dna was isolated from both plant species and used for the amplification, cloning, and sequencing of the begomovirus genome. nucleotide comparison of the complete dna-a component isolated from s. acuta and c. siliquosus confirmed the presence of two distinct begomoviruses species. based on phenotypic symptoms observed in infected field pla ... | 2007 | 17638064 |
