| pepper leaf curl lahore virus requires the dna b component of tomato leaf curl new delhi virus to cause leaf curl symptoms. | begomoviruses are whitefly-transmitted geminiviruses with genomes that consist of either two components (known as dna a and dna b) or a single component (homologous to the dna a component of bipartite begomoviruses). monopartite begomoviruses are often associated with a symptom-modulating dna satellite (collectively known as betasatellites). both bipartite and monopartite begomoviruses with associated satellites have previously been identified in chillies showing leaf curl symptoms in pakistan. | 2010 | 21144019 |
| 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 |
| the hypersensitive response to tomato leaf curl new delhi virus nuclear shuttle protein is inhibited by transcriptional activator protein. | the hypersensitive response (hr) is a common feature of plant disease resistance reactions and a type of programmed cell death (pcd). many pathogens are able to modulate pathways involved in cell death. in contrast to animal viruses, inhibitors of pcd activity have not been identified for plant-infecting viruses. previously, we have reported that the nuclear shuttle protein (nsp) of tomato leaf curl new delhi virus (tolcndv) induces an hr in nicotiana tabacum and lycopersicon esculentum plants w ... | 2007 | 17990965 |
| the nuclear shuttle protein of tomato leaf curl new delhi virus is a pathogenicity determinant. | the role of the movement protein (mp) and nuclear shuttle protein (nsp) in the pathogenicity of tomato leaf curl new delhi virus (tolcndv), a bipartite begomovirus, was studied. both genes were expressed in nicotiana benthamiana, nicotiana tabacum, and lycopersicon esculentum plants with the potato virus x (pvx) expression vector or by stable transformation of gene constructs under the control of the 35s promoter in n. tabacum. no phenotypic changes were observed in any of the three species when ... | 2005 | 15767443 |
