supervirulent pseudorecombination and asymmetric synergism between genomic components of two distinct species of begomovirus associated with severe tomato leaf curl disease in india.	isolates of two distinct begomovirus species, the severe strain of the species tomato leaf curl new delhi virus (tomato leaf curl new delhi virus-[india:new delhi:severe:1992]; tolcndv-[in:nd:svr:92], bipartite) and the varanasi strain of the species tomato leaf curl gujarat virus (tomato leaf curl gujarat virus-[india:varanasi:2001]; tolcgv-[in:var:01], mono/bipartite) infect tomato (lycopersicon esculentum) and cause severe yield losses in northern india. this study investigated the infectivit ...	2008	18272774
molecular characterization of a new species of begomovirus and betasatellite causing leaf curl disease of tomato in india.	a new tomato-infecting begomovirus and cognate betasatellite were characterized from the gangetic plain of northern india. genome organization of this virus was found to be similar to those of other old world begomoviruses. the dna-a molecule (2752nt) shared maximum (85.8%) identity with tomato leaf curl laos virus-[laos] (tolclv-[la]; af195782) from laos and betasatellite molecule (1349nt) shared maximum (75.8%) identity with tomato leaf curl joydebpur betasatellite (tolcjob-[bd:gaz:05]; aj9662 ...	2010	20540978
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
synergistic interaction among begomoviruses leads to the suppression of host defense-related gene expression and breakdown of resistance in chilli.	chilli (capsicum sp.) is one of the economically important spice and vegetable crops grown in india and suffers great losses due to the infection of begomoviruses. conventional breeding approaches have resulted in development of a few cultivars of chilli resistant to begomoviruses. a severe leaf curl disease was observed on one such resistant chilli cultivar (capsicum annuum cv. kalyanpur chanchal) grown in the experimental field of the jawaharlal nehru university, new delhi. four different vira ...	2016	26780359
