preliminary identification and coat protein gene phylogenetic relationships of begomoviruses associated with native flora and cultivated plants from the yucatan peninsula of mexico. | a number of native and cultivated eudicots in the yucatan peninsula of mexico (ypm) exhibit symptoms associated with virus infection. symptomatic leaves were collected and assessed for begomoviral detection using polymerase chain reaction (pcr), and universal primers that amplify a fragment of the coat protein gene (core cp). begomovirus were detected in nine native and seven cultivated species, representing seven eudicot families. dna extracts from the 16 hosts were used for pcr amplification a ... | 2007 | 17682933 |
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 |
