The 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 کاملAre 'Pathogenesis-related' Proteins Involved in Acquired Systemic Resistance of Tobacco Plants to Tobacco Mosaic Virus
Four host-coded 'pathogenesis-related' proteins accumulate systemically in locallesion-forming varieties of tobacco after infection with tobacco mosaic virus. It has been suggested that they are involved in the acquired systemic resistance of plants to a second inoculation. Pathogenesis-related protein concentration and amount of resistance (reduction in size and number of lesions formed in the...
متن کاملCyanide 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 کاملLocation of unique sequences in tobacco mosaic virus ribonucleic acid.
Tobacco mosaic virus has been partially stripped of its protein coat by sodium dodecyl sulfate. The nucleic acid exposed was digested with T1 ribonuclease and the products were examined for the presence of three oligonucleotides of unique sequence. The results indicate the location of two of the unique oligomers to be near the 5’-OH-linked end and the third to be near the middle of tobacco mosa...
متن کاملInduction of UDP-Glucose:Salicylic Acid Glucosyltransferase Activity in Tobacco Mosaic Virus-Inoculated Tobacco (Nicotiana tabacum) Leaves.
Salicylic acid (SA) is a putative signal that activates plant resistance to pathogens. SA levels increase systemically following the hypersensitive response produced by tobacco mosaic virus (TMV) inoculation of tobacco (Nicotiana tabacum L. cv Xanthi-nc) leaves. The SA increase in the inoculated leaf coincided with the appearance of a [beta]-glucosidase-hydrolyzable SA conjugate identified as [...
