Cyanide restores N gene-mediated resistance to tobacco mosaic virus in transgenic tobacco expressing salicylic acid hydroxylase
Salicylhydroxamic acid (SHAM), an inhibitor of alternative oxidase (AOX), blocks salicylic acid-induced resistance to tobacco mosaic virus (TMV) but does not inhibit pathogenesis-related PR-1 protein synthesis or resistance to fungal and bacterial pathogens. We found that the synthetic resistance-inducing chemical 2, 6-dichloroisonicotinic acid also induced Aox transcript accumulation and SHAM-...
متن کاملRNAi-mediated oncogene silencing confers resistance to crown gall tumorigenesis.
Crown gall disease, caused by the soil bacterium Agrobacterium tumefaciens, results in significant economic losses in perennial crops worldwide. A. tumefaciens is one of the few organisms with a well characterized horizontal gene transfer system, possessing a suite of oncogenes that, when integrated into the plant genome, orchestrate de novo auxin and cytokinin biosynthesis to generate tumors. ...
متن کاملThe N gene of tobacco confers resistance to tobacco mosaic virus in transgenic tomato.
It has been proposed that cloned plant disease resistance genes could be transferred from resistant to susceptible plant species to control important crop plant diseases. The recently cloned N gene of tobacco confers resistance to the viral pathogen, tobacco mosaic virus. We generated transgenic tomato plants bearing the N gene and demonstrate that N confers a hypersensitive response and effect...
متن کاملRNAi-derived transgenic resistance to Mungbean yellow mosaic India virus in cowpea
Cowpea is an important grain legume crop of Africa, Latin America, and Southeast Asia. Leaf curl and golden mosaic diseases caused by Mungbean yellow mosaic India virus (MYMIV) have emerged as most devastating viral diseases of cowpea in Southeast Asia. In this study, we employed RNA interference (RNAi) strategy to control cowpea-infecting MYMIV. For this, we generated transgenic cowpea plants ...
متن کاملExpression and antimicrobial activity analysis of dermaseptin B1 recombinant peptides in tobacco transgenic plants
Recently, new molecular breeding and genetic engineering approaches have emerged to overcome the limitations of conventional breeding methods in generating disease-resistance transgenic plants. The use of antimicrobial peptides (AMPs) to produce transgenic plants resistant to a wide range of plant pathogens has achieved great success. Among huge number of AMPs, Dermaseptin B1 (DrsB1), an antimi...
