Homologues of the Arabidopsis NIM1 gene, which is involved in the signal transduction cascade leading to systemic acquired resistance (SAR), are isolated from Nicotiana tabacum (tobacco), Lycopersicon esculentum (tomato), Brassica napus (oilseed rape), Arabidopsis thaliana, Beta vulgaris (sugarbeet), Helianthus annuus (sunflower), and Solanum tuberosum (potato). The invention further concerns transformation vectors and processes for expressing the NIM1 homologues in transgenic plants to increase SAR gene expression and enhance broad spectrum disease resistance.
L'invention concerne des homologues du gène Arabidopsis NIM1, impliqué dans la cascade de transduction des signaux menant à la résistance systémique acquise (RSA), qui sont isolés à partir de Nicotiana tabacum (tabac), de Lycopersicon esculentum (tomate), de Brassica napus (colza oléagineux), d'Arabidopsis thaliana, de Beta vulgaris (betterave à sucre), d'Helianthus annuus (tournesol) et de Solanum tuberosum (pomme de terre). L'invention concerne également des vecteurs de transformation et des processus permettant d'exprimer les homologues de NIM1 dans des végétaux transgéniques afin d'accroître l'expression du gène RSA et d'élargir le large spectre de résistance aux maladies.
