| 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 |
| emergence of a new cucurbit-infecting begomovirus species capable of forming viable reassortants with related viruses in the squash leaf curl virus cluster. | abstract cucurbit leaf curl virus (culcv), a whitefly-transmitted geminivirus previously partially characterized from the southwestern united states and northern mexico, was identified as a distinct bipartite begomovirus species. this virus has near sequence identity with the previously partially characterized cucurbit leaf crumple virus from california. experimental and natural host range studies indicated that culcv has a relatively broad host range within the family cucurbitaceae and also inf ... | 2002 | 18943269 |
| biotic, molecular, and phylogenetic characterization of bean calico mosaic virus, a distinct begomovirus species with affiliation in the squash leaf curl virus cluster. | abstract bean calico mosaic virus (bcmov), a whitefly-transmitted geminivirus from sonora, mexico, was purified, and the genome components were cloned and sequenced. purified viral fractions and cloned genome components were infectious by biolistic inoculation to bean, completing koch's postulates for both. the b biotype of the whitefly bemisia tabaci efficiently transmitted both native virus and progeny virus derived from cloned dna inoculum. host ranges of native virus and of progeny virus der ... | 1999 | 18944770 |
