Self-incompatibility is a mechanism that prevents pollen from one flower from fertilizing other flowers of the same plant. Self-incompatibility is often observed in plants belonging to such families as Solanaceae and Rosaceae.
What does self-incompatibility provide for a plant?
Self-incompatibility is a widespread mechanism in flowering plants that prevents inbreeding and promotes outcrossing. The self-incompatibility response is genetically controlled by one or more multi-allelic loci, and relies on a series of complex cellular interactions between the self-incompatible pollen and pistil.
What is a benefit of self-incompatibility?
Self-incompatibility helps in preventing self-pollination. It favours cross-pollination. Self-pollination leads to inbreeding depression.
