In the Brassica self-incompatibility (SI) system, a pollen determinant, SP11, is involved in dominance/recessive relationships in pollen SI phenotypes. In order to gain some insights into the genomic structure around the SP11 and the mechanisms that give dominance/recessive relationships, we characterized the genomic region containing SP11 and SRK genes in three pollen recessive class-II S haplotypes. The direction of transcription of S genes was completely conserved among class-II S haplotypes. However, the region between SP11 and SRK (S-intergenic region) was highly polymorphic without short repetitive sequences. In addition, we found a sequence similarity between the short repetitive sequence and 5′-upstream region of SP11. This sequence similarity was found to be potentially related to the expression of dominance relationships through the change of chromatin structure.
