| occurrence and significance of cryptococcus neoformans in vegetables and fruits. | cryptococcus neoformans was isolated from three of 437 (0.6%) samples of a wide variety of vegetables collected from a number of markets in delhi. the vegetables yielding c. neoformans were tomato, lycopersicon esculentum (1/70), 'vegetable sponge', luffa cylindrica (1/56) and brinjal, solanum melongena (1/55). only solitary samples of these three vegetables were found to be positive. in vitro studies at 25 degrees c revealed that a reference c. neoformans isolate readily colonized, as did candi ... | 2000 | 15597680 |
| 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 |
| characterisation and diagnosis of frangipani mosaic virus from india. | frangipani mosaic virus (frmv) is known to infect frangipani tree (plumeria rubra f. acutifolia) in india but the virus has not been characterized at genomic level and diagnosis is not available. in the present study, an isolate of frmv (frmv-ind-1) showing greenish mosaic and vein-banding symptoms in p. rubra f. acutifolia in new delhi was characterized based on host reactions, serology and genome sequence. the virus isolate induced local symptoms on several new experimental host species: capsi ... | 2015 | 26239043 |
