| 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 ... | 2003 | 12767699 |
| ferredoxin from sweet pepper (capsicum annuum l.) intensifying harpin(pss)-mediated hypersensitive response shows an enhanced production of active oxygen species (aos). | the hypersensitive response (hr) is a form of cell death associated with plant resistance to pathogen infection. harpin(pss), an elicitor from the bacterium pseudomonas syringae pv. syringae, induces a hr in non-host plants. previously, we reported an amphipathic protein from sweet pepper interfering with harpin(pss)-mediated hr. in this report, we isolated and characterized a cdna clone encoded that amphipathic protein from sweet pepper. this protein is designated as pflp (plant ferredoxin-like ... | 2003 | 12777051 |
| the sweet pepper ferredoxin-like protein (pflp) conferred resistance against soft rot disease in oncidium orchid. | genetic engineering to date has not been used to introduce disease resistance genes into the orchid gene pool. the ferredoxin-like protein gene originally isolated from sweet pepper is thought to function as a natural defense against infection due to its antimicrobial properties. hence it was reasoned that introduction of this gene might produce oncidium plants resistant to erwinia carotovora, the causal agent for the soft rot disease. an expression vector containing sweet pepper ferredoxin-like ... | 2003 | 12779121 |
| binary transformation systems based on 'shooter' mutants of agrobacterium tumefaciens: a simple, efficient and universal gene transfer technology that permits marker gene elimination. | a simple transformation procedure with a positive selection scheme using the expression of the isopentenyl transferase ( ipt) gene of transfer dna (t-dna) 'shooter' mutants of agrobacterium tumefaciens was elaborated. after comparing several 'shooter' mutants we found that particular strains frequently produced phenotypically normal shoots after co-culturing with tobacco leaf explants. shoots selected for normal phenotype showed apical dominance and could be rooted with the same efficiency as no ... | 2003 | 12789522 |
