The Resistance gene is a member of the NBS-LRR (Nucleotide Binding
Site - Leucine Rich Repeat) class and codes for a protein that
recognise specific proteins - termed elicitor proteins - of
Phytophthora infestans the causing agent of late-blight disease.
Recognition of the elicitor proteins will lead to local plant cell
death and will thus prevent further development of the pathogen
Phytophthora infestans.
The precise molecular basis of R gene/single-gene and quantitative
resistance to late blight is unknown.
