Abstract
Self-incompatibility in Brassica campestris is controlled by two complementary genes, the long-established S gene with sporophytic action on the pollen and a pollen-gametophytically active gene, G, which is complementary to S and is oppositional in its action in that both S and G alleles must be matched to give an incompatible reaction.
The G genes in both Brassica campestris and Raphanus sativus are closely similar. They appear to have, in both species, a low number of alleles, are fully expressed only in some S allele combinations and are linked to S. The evidence suggests that G is the forerunner of the gene in the gametophytic system in dicotyledons and has been retained in the sporophytic system as an essential part of the incompatibility process.
