WebWe demonstrate by in situ hybridization the cell-type-specific expression of transcripts encoded by the self-incompatibility (S) locus of Brassica oleracea.These transcripts are not detected early in stigma development, their expression is switched on in the papillar cells of the stigma surface, and their levels increase in these cells in correlation with the … 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].
