SRK (S-locus receptor kinase) is the receptor that allows stigma epidermal cells to discriminate between genetically related ('self') and genetically unrelated ('non-self') pollen in the self-incompatibility response of the Brassicaceae. SRK and its ligand, the pollen coat-localized SCR (S-locus cysteine-rich protein), are highly polymorphic, and their allele-specific interaction explains specificity in the self-incompatibility response. The present article reviews current knowledge of the role of SRK in the recognition and response phases of self-incompatibility, and highlights the new insights provided by analysis of a transgenic self-incompatible Arabidopsis thaliana model.
