| molecular characterization and experimental host range of an isolate of wissadula golden mosaic st. thomas virus. | partial genome segments of a begomovirus were previously amplified from wissadula amplissima exhibiting yellow-mosaic and leaf-curl symptoms in the parish of st. thomas, jamaica and this isolate assigned to a tentative begomovirus species, wissadula golden mosaic st. thomas virus. to clone the complete genome of this isolate of wissadula golden mosaic st. thomas virus, abutting primers were designed to pcr amplify its full-length dna-a and dna-b components. sequence analysis of the complete bego ... | 2009 | 19768650 |
| sinaloa tomato leaf curl geminivirus: biological and molecular evidence for a new subgroup iii virus. | abstract the biological and molecular properties of sinaloa tomato leaf curl virus (stlcv) were investigated in line with the hypothesis that stlcv is a previously uncharacterized, whitefly-transmitted geminivirus from north america. stlcv causes yellow leaf curl symptoms in tomato and yellow-green foliar mottle in pepper. five species belonging to two plant families were stlcv experimental hosts. stlcv had a persistent relationship with its whitefly vector, bemisia tabaci. polymerase chain reac ... | 1998 | 18944936 |
| sequence characterization of tomato leaf curl sinaloa virus and tomato severe leaf curl virus: phylogeny of new world begomoviruses and detection of recombination. | diseases caused by begomoviruses (family geminiviridae, genus begomovirus) constitute a serious constraint to tomato production in nicaragua. in this study, the complete nucleotide (nt) sequences of the dna-a and dna-b components were determined for the first time for tomato leaf curl sinaloa virus (tolcsinv). in addition, the complete nt sequence was determined for the dna-a component of two isolates of tomato severe leaf curl virus (toslcv). the genome organization of tolcsinv and toslcv was i ... | 2005 | 15789265 |
