Abstract excerpt

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...
