Popis:	The BrassicaS product of the pollen-signalling S-gene (SP11 for Specificity Pollen, or SCR for S locus Cysteine Rich) has recently been identified as a member of the family of PCPs (Pollen Coat Proteins), a group of small basic proteins. In female plants SRK (SReceptor Kinase) has been demonstrated, among several stigma-expressed S genes, to exclusively control self-pollen rejection. Genes and gene products that are highly related to the sporophytic SI system appear to take part in the control of several stages of pollen-stigma interactions in the Brassicaceae. These genes ensure, in particular, the species specificity of late pollen adhesion. Pollen capture itself is not species specific, since it depends essentially on lipophilic affinities between pollen coatings and waxy pellicles on the stigma. These interactions and their control are reviewed here.
