Self-incompatibility (SI) is a widespread mechanism in angiosperms which prevents self-fertilization. This mechanism relies on cell-cell interactions between pollen and pistil. Among the different SI systems that have been reported, two have been particularly investigated: the gametophytic system of Solanaceae and the sporophytic system of Brassicaceae. In these two families, although the molecular bases of SI response are different, secreted and/or membrane-anchored proteins are required for self-pollen rejection. Interestingly, these proteins exhibit two functions: recognition and a catalytic activity. In this review article, we present recent advances which permit a better understanding of how these proteins control the male/female recognition event associated with the SI response
