PLANT RESISTANCE GENE

摘要

Disclosed are isolated nucleic acid molecules comprising an RPP1 nucleotide sequence which encodes a Peronospora parasitica resistance gene of the RPP1 complex locus, such as the RPP1 homologues A, B and C from Arabidopsis thaliana Wassilewskija various of which have specificities corresponding to RPP1, 10 and 14. Also disclosed are variants of these sequences, which may be natural homologues or derivatives. The invention further provides probes and primers, vectors, host cells, and transgenic plants, plus corresponding methods of producing and employing the same.
