| nucleotide sequencing, whitefly transmission, and screening tomato for resistance against two newly described begomoviruses in bangladesh. | abstract the molecular diversity of tomato leaf curl viruses (tolcvs), from the two main tomato growing areas of jessore and joydebpur, bangladesh, was investigated. the viral dna was amplified from tomato plants exhibiting mild and severe symptoms by polymerase chain reaction, and the complete genomes of the tolcvs were sequenced. an isolate of the bipartite tomato leaf curl new delhi virus-severe (tolcndv-svr) was associated with the severe symptom phenotype from jessore (tolcndv-svr[jes]). a ... | 2005 | 18943559 |
| complete nucleotide sequences of a distinct bipartite begomovirus, bitter gourd yellow vein virus, infecting momordica charantia. | momordica charantia (cucurbitaceae), a vegetable crop commonly cultivated throughout pakistan, and begomoviruses, a serious threat to crop plants, are natives of tropical and subtropical regions of the world. leaf samples of m. charantia with yellow vein symptoms typical of begomovirus infections and samples from apparently healthy plants were collected from areas around lahore in 2004. full-length clones of a bipartite begomovirus were isolated from symptomatic samples. the complete nucleotide ... | 2010 | 20924621 |
| a novel recombinant tomato-infecting begomovirus capable of transcomplementing heterologous dna-b components. | the genome of a tomato-infecting begomovirus from ranchi, india, was cloned, sequenced and analysed. the viral genome shared 88.3% sequence identity with an isolate belonging to the species tobacco curly shoot virus (tbcsv), and this virus should therefore be considered a member of a new species, tentatively named tomato leaf curl ranchi virus (tolcrnv). the dna-ß molecule, which had 74.5% sequence identity with tomato leaf curl bangladesh betasatellite (tolcbdb), is named tomato leaf curl ranch ... | 2011 | 21311922 |
| biology and interactions of two distinct monopartite begomoviruses and betasatellites associated with radish leaf curl disease in india. | emerging whitefly transmitted begomoviruses are major pathogens of vegetable and fibre crops throughout the world, particularly in tropical and sub-tropical regions. mutation, pseudorecombination and recombination are driving forces for the emergence and evolution of new crop-infecting begomoviruses. leaf curl disease of field grown radish plants was noticed in varanasi and pataudi region of northern india. we have identified and characterized two distinct monopartite begomoviruses and associate ... | 2012 | 22339942 |
