Self-incompatibility (SI) is a genetic mechanism to prevent self-fertilization that is found in many species of flowering plants. Molecular studies have demonstrated that the S-RNase and SLF/SFB genes encoded by the single polymorphic S locus, which control the pollen and pistil functions of SI in three distantly related families, the Solanaceae, Scrophulariaceae and Rosaceae, are organized in a haplotype-specific manner. Previous work suggested that the haplotype structure of the two genes is… CONTINUE READING
