A barley receptor-like protein kinase (RLK) gene was knocked down by VIGS.
Expression of numerous pathogen defense-related genes was reduced by this treatment.
20">Expression of the RLK gene depended on the allelic state of the Mla locus.
25">The RLK gene was induced by powdery mildew and stem rust infection.
The characterized gene may act in the detection of fungal pathogens.
