In crucifers, the pollen S-determinant gene, SP11, is sporophytically expressed in the anther tapetum, and the pollen self-incompatibility phenotype is determined by the dominance relationships between the two S-haplotypes it carries. We report here that 5′ promoter sequences of recessive SP11 alleles are specifically methylated in the tapetum before the initiation of SP11 transcription. These results suggest that tissue-specific monoallelic de novo DNA methylation is involved in determining the dominance interactions that determine the cruciferous self-incompatibility phenotype.
