WebSelf-incompatibility is a fundamental mechanism to prevent inbreeding. In this process, interaction between pollen and pistil is required for recognizing self or nonself [114]. In Brassica plants, S-locus cysteine-rich (SCR) protein was identified as a determinant for pollen side in self-incompatibility [115].
