Self-incompatibility in angiosperms: A review


After a survey of the earlier descriptions of incompatibility, the genetical analyses are reviewed of gametophytic-, sporophytic- and heteromorphic incompatibility, of the behaviour in polyploids, and of S-mutations. The cytological observations refer to the site of inhibition of pollen tube growth and nucleate state of the pollen. Modern theories on the biochemical nature of the incompatibility reaction are compared. Finally, some evolutionary aspects are summarized.
