Plant Biology One Way to Avoid Pollen

Certain types of plants encourage cross-fertilization in their populations by biochemical means--polymorphic components on the pollen grain and the stigma allow the plant to recognize and avoid responding to its own pollen. This self-incompatibility is mediated by SRK, a receptor-like kinase, on the surface of the stigma, and SCR, a protein on the surface of the pollen. Kachroo et al. have now demonstrated that SRK and SCR form a receptor-ligand pair that interacts molecularly.
