Abstract (en)
[origin: WO0107596A1] The cell death response known as the hypersensitive response (HR) is a central feature of gene-for-gene plant disease resistance. Plants also defend against pathogens via multigenically controlled broad-spectrum defense responses, such as those modulated by salicylic acid. The <i>DND</i> (Defense, No Death) loci of <i>Arabidopsis thaliana</i> regulate the extent of broad-spectrum disease resistance against a broad range of viral, bacterial, oomycete and fungal pathogens. Plants lacking a functional copy of the <i>DND1</i> or <i>2</i> gene are defective in HR cell death but exhibit successful gene-for-gene disease resistance. Plants lacking a functional copy of the <i>DND1</i> or <i>2</i> gene also exhibit an enhanced broad-spectrum disease resistance phenotype. The <i>DND1</i> and <i>2</i> gene products are identical to previously known cDNAs termed <i>AtCNGC2</i> and <i>1</i>, respectively, that encode apparent cyclic nucleotide-gated ion channel proteins. The identification of the <i>CNGC/DND</i> genes as regulators of disease resistance and host cell death, and the availability of <i>CNGC/DND</i> gene sequence information, provide new possibilities for controlling a wide variety of plant diseases.
