safety assessment for genetically modified sweet pepper and tomato.the coat protein (cp) gene of cucumber mosaic virus (cmv) was cloned from a chinese cmv isolate, the camv promoter and nos terminator added and the gene construct was transformed into both sweet pepper and tomato plants to confer resistance to cmv. safety assessments of these genetically modified (gm) plants were conducted. it was found that these two gm products showed no genotoxicity either in vitro or in vivo by the micronucleus test, sperm aberration test and ames test. animal feeding studie ...200312767699
toward a quarter century of pathogen-derived resistance and practical approaches to plant virus disease control.the concept of pathogen-derived resistance (pdr) describes the use of genetic elements from a pathogen's own genome to confer resistance in an otherwise susceptible host via genetic engineering [j. theor. biol. 113 (1985) 395]. illustrated with the bacteriophage qbeta in escherichia coli, this strategy was conceived as a broadly applicable approach to engineer resistance against pathogens. for plant viruses, the concept of pdr was validated with the creation of tobacco plants expressing the coat ...201020109666
genetic compositions of broad bean wilt virus 2 infecting red pepper in korea.the incidence of broad bean wilt virus 2 (bbwv2) on red pepper was investigated using the samples obtained from 24 areas of 8 provinces in korea. two hundred and five samples (79%) out of 260 collected samples were found to be infected with bbwv2. while the single infection rate of bbwv2 was 21.5%, the co-infection rate of bbwv2 with cucumber mosaic virus, pepper mottle virus, pepper mild mottle virus and/or potato virus y was 78.5%. to characterize the genetic diversity of bbwv2 korean isolates ...201325288954
transgenic sweet pepper plants fromagrobacterium mediated transformation.fertile transgenic sweet pepper (capsicum annuum var. grossum) plants were regenerated at relatively high rate from various explants that were cocultivated withagrobacterium tumefaciens strain gv3111-se harbouring a plasmid that contains the cucumber mosaic virus coat protein (cmv-cp) gene. the rate of plant regeneration was found to depend on the types of explants cultured and the media used. young leaves were most effective for bud induction and subsequent plant elongation while hypocotyls wer ...199624178658
