Overexpression of a kinase-deficient form of the EDR1 gene enhances powdery mildew resistance and ethylene-induced senescence in Arabidopsis.


The EDR1 gene of Arabidopsis has previously been reported to encode a Raf-like mitogen-activated protein kinase kinase (MAPKK) kinase, and to function as a negative regulator of disease resistance. A phylogenetic analysis of plant and animal protein kinases revealed, however, that plant Raf-like kinases are more closely related to animal mixed lineage… (More)
