摘要: Self-incompatibility (SI) is a common form of genetically-controlled mate-selection that prevents mating between closely related plants the same species. SI occurs in about half all flowering plant It has been studied extensively Papaveraceae (poppy), Brassicaceae (Arabidopsis, cabbage etc), Solanaceae (potato, tomato Plantaginaceae (snapdragon) and Rosaceae (apple, cherry peach etc). The self-recognition inherent self-incompatibility similarities with animal immunity systems giving rise to speculation are related. Both display balancing selection, ‘self/nonself’ recognition, high polymorphism, specificity there also some rejection mechanisms deployed two systems. Whether these have diverged from predecessor discussed, however may be driven more by biological problems available molecular machinery solve them than an evolutionary relationship.
