Abstract
Sexual reproduction in legion(predicate) ?owering plants involves selfincompatibility (SI), which is one of the most important systems to prevent inbreeding. In galore(postnominal) species, the self-/nonself-recognition of SI is controlled by a single polymorphic locus, the S-locus. molecular dissection of the S-locus revealed that SI represents not one system, but a array of divergent mechanisms. Here, we discuss recent advances in the understanding of terzetto distinct SI mechanisms, each controlled by two crock up determinant genes at the S-locus.



In the Brassicaceae, the determinant genes encode a pollen ligand and its discolorationtic receptor kinase; their interaction induces incompatible signaling(s) within the stigma papilla cells. In the Solanaceae-type SI, the determinants are a ribonuclease and an F-box protein, suggesting the involvement of ribonucleic acid and protein degradation in the system. In the Papaveraceae, the only identi?ed effeminate determinant induces a Ca2+ -dependent signaling network that ultimately results in the death of incompatible pollen.
