Abstract:

Selfincompatibility (SI) is a major genetic mechanism to prevent selffertilization in flowering plants and, in most cases, controlled by a single multiallelic locus, known as the S locus. In Brassica, the genes mediating both stylar (SRK, S receptor kinase) and pollen (SCR/SP11, S locus cystein rich protein/S locus protein 11) expression of selfincompatible reaction have been characterized though the first S locus-encoded gene, SLG (S locus glycoprotein), was isolated nearly fifteen years ago. These findings have finally unveiled the molecular partners in pollen recognition during selfincompatible reaction in Brassica.
