phylogenetic analysis of melon chlorotic leaf curl virus from guatemala: another emergent species in the squash leaf curl virus clade. | the genome of a new bipartite begomovirus melon chlorotic leaf curl virus from guatemala (mclcuv-gt) was cloned and the genome sequence was determined. the virus causes distinct symptoms on melons that were not previously observed in melon crops in guatemala or elsewhere. phylogenetic analysis of mclcuv-gt and begomoviruses infecting cucurbits and other host plant species indicated that its closest relative was mclcuv from costa rica (mclcuv-cr). the dna-a components of two isolates shared 88.8% ... | 2011 | 21420452 |
melon chlorotic leaf curl virus: characterization and differential reassortment with closest relatives reveal adaptive virulence in the squash leaf curl virus clade and host shifting by the host-restricted bean calico mosaic virus. | the genome components of the melon chlorotic leaf curl virus (mclcuv) were cloned from symptomatic cantaloupe leaves collected in guatemala during 2002. the mclcuv dna-a and dna-b components shared their closest nucleotide identities among begomoviruses, at approximately 90 and 81%, respectively, with a papaya isolate of mclcuv from costa rica. the closest relatives at the species level were other members of the squash leaf curl virus (slcv) clade, which is endemic in the southwestern united sta ... | 2008 | 18057231 |
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 |
