[Molecular mechanism of self-incompatibility in Brassica].
In Brassica species, self-incompatibility has been mapped genetically to a single chromosomal location. In this region several closely linked genes have been identified. One of them, S-locus receptor kinase (SRK), determines S haplotype specificity of the stigma and it's the key protein for SI reaction. The role of the S locus glycoprotein (SLG) gene remains unclear. In the last decade approxim...
متن کاملThe pollen determinant of self-incompatibility in Brassica campestris.
Many flowering plants possess self-incompatibility (SI) systems that prevent inbreeding. In Brassica, SI is controlled by a single polymorphic locus, the S locus. Two highly polymorphic S locus genes, SLG (S locus glycoprotein) and SRK (S receptor kinase), have been identified, both of which are expressed predominantly in the stigmatic papillar cell. We have shown recently that SRK is the deter...
متن کاملEvolutionary dynamics of self-incompatibility alleles in Brassica.
Self-incompatibility in Brassica entails the rejection of pollen grains that express specificities held in common with the seed parent. In Brassica, pollen specificity is encoded at the multipartite S-locus, a complex region comprising many expressed genes. A number of species within the Brassicaceae express sporophytic self-incompatibility, under which individual pollen grains bear specificiti...
متن کاملCharacterization of the SP11/SCR high-affinity binding site involved in self/nonself recognition in brassica self-incompatibility.
In Brassica self-incompatibility, the recognition of self/nonself pollen grains, is controlled by the S-locus, which encodes three highly polymorphic proteins: S-locus receptor kinase (SRK), S-locus protein 11 (SP11; also designated S-locus Cys-rich protein), and S-locus glycoprotein (SLG). SP11, located in the pollen coat, determines pollen S-haplotype specificity, whereas SRK, located on the ...
متن کاملStructure of the male determinant factor for Brassica self-incompatibility.
Many flowering plants possess a self-incompatibility system to prevent inbreeding. In Brassica rapa, self/non-self recognition in mating is established through S-haplotype-specific interactions between stigma receptors and S-locus protein 11 (SP11, also called S-locus cysteine-rich protein) that is encoded at the highly polymorphic S-locus. Here we describe the solution structure of the SP11 pr...
