Incompatibility in Angiosperms

摘要: Since Darwinian times considerable knowledge has accumulated on the distribution, physiology and genetics of self-incompatibility (SI) in higher plants, In second half this century first attempts were made to identify biochemical bases SI. These included discovery that cutinase enables pollen tube penetration at surface stigma Cruciferae, sorting segregation S-phenotypes by serological techniques, a lock-and-key model SI reaction, detection characterisation proteins role tapetum determination phenotypes homomorphic sporophytic This pioneering work was followed worldwide effort understand cellular molecular processes which lead recognition rejection pollen. The present review article summarizes briefly current state areas essential for understanding exploitation outlines new information become available during recent years.
