Recent work has furthered our understanding of the molecules involved, and the diversity of mechanisms displayed, in self-incompatibility. S-RNases have been identified in two more plant families and their structure/function relationships are currently being dissected. Novel S genes have been cloned and expressed in Papaver rhoeas and Phalaris coerulescens, and the complexity of the S locus in Brassica is being unraveled. Present data implicate the involvement of protein kinase activity in all systems where pollen inhibition occurs at the stigma surface and RNase activity in those systems displaying stylar inhibition.
