Self-compatibility (SC) is the absence of genetic mechanisms which prevent self-fertilization resulting in plants that can reproduce successfully via both self-pollen and pollen from other individuals. Approximately one half of angiosperm species are SI, the remainder being SC. Mutations that disable SI (resulting in SC) may become common or entirely dominate in natural populations. Pollinator decline, variability in pollinator service, the so-called "automatic advantag… 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].
