Disease Resistant Plants

摘要

The present invention relates to a plant, which is resistant to a pathogen of viral, bacterial, fungal or oomycete origin, wherein the plant has a reduced level, reduced activity or complete absence of DMR6 protein as compared to a plant that is not resistant to the said pathogen, in particular organisms of the Fungi or the phylum Oomycota. The invention further relates to a method for obtaining a plant, which is resistant to a pathogen of viral, bacterial, fungal or oomycete origin, comprising reducing the endogenous level or activity of DMR6 protein in the plant. In addition, the invention relates to the use of a DMR6 promotor for providing disease resistant plants.
