| characterization of tomato yellow vein streak virus, a begomovirus from brazil. | tomato yellow vein streak virus (toyvsv) is a tentative begomovirus (family geminiviridae) species that seriously affects tomato and potato production in brazil. here, we have determined the genomic and biological characteristics of a toyvsv isolate (ba3) from a potato plant sampled in rio grande do sul state, brazil. the dna-a nucleotide sequence of ba3 and another previously reported toyvsv isolate share 89.7% sequence identity. these toyvsv isolates should be classified as a new species in th ... | 2010 | 19937269 |
| tomato mottle wrinkle virus, a recombinant begomovirus infecting tomato in argentina. | begomoviruses seriously threaten tomato production in south america. here, we present the molecular characterization of a novel tomato-infecting begomovirus isolated in argentina and demonstrate its infectivity. after cloning and sequencing the complete genome of this new virus, pairwise genetic distance and phylogenetic analyses revealed that it is a novel virus that is closely related to other begomoviruses found in argentina, brazil and bolivia. we have proposed naming the virus tomato mottle ... | 2015 | 25252814 |
