| molecular characterization of two distinct monopartite begomoviruses infecting tomato in india. | tomato leaf curl viruses, which are the members of the genus begomovirus, have emerged as devastating pathogens worldwide causing huge economic losses and threatening production of crops like cassava, cotton, grain legumes and vegetables. even though the tolcv isolates from northern india have been shown to possess bipartite genome (designated as dna a and dna b), those from australia, taiwan and southern india have a single genomic component (dna a). we describe here the genetic diversity of tw ... | 2010 | 21092241 |
| a betasatellite-dependent begomovirus infects ornamental rose: characterization of begomovirus infecting rose in pakistan. | the begomovirus genus of the family geminiviridae comprises the largest group of geminiviruses. the list of begomoviruses is continuously increasing as a result of improvement in the methods for identification. ornamental rose plants (rosa chinensis) with highly stunted growth and leaf curling were found in faisalabad, pakistan. plants were analyzed for begomovirus infection, through rolling circle amplification and pcr methods. based on complete genome sequence homologies with other begomovirus ... | 2014 | 24781196 |
| detection and characterization of a new betasatellite: variation in disease symptoms of tomato leaf curl pakistan virus-india due to associated betasatellite. | a begomovirus and its associated betasatellites were amplified and sequenced from tobacco plants affected with leaf curl disease. the begomovirus was identified as a new strain of tomato leaf curl pakistan virus (tolcpkv), which is referred to here as tolcpkv-india. a previously known betasatellite [tomato leaf curl patna betasatellite (tolcpab)] and a new betasatellite were also found in leaf-curl-affected samples. the use of infectious clones of tolcpkv-in plus tolcpab for agroinoculation led ... | 2013 | 23053516 |
