Self-incompatibility (SI) is a prezygotic mechanism that prevents self-pollination in flowering plants by distinguishing between nonself- and self-pollen. It controls sexual reproduction promoting outcrossing avoiding inbreeding. For thousands of years, this trait has been effectively exploited breeders growers as tool to manipulate domesticated crops. However, efforts spell out the molecular features SI have begun only during past thirty years. need produce homozygous lines, undesirable. Moreover, fruit crops, hinders production true type high-quality fruits with uniform traits because favors outcrossing. Numerous techniques developed break down SI. Here, we review current understanding different systems pinpoint physiological used We also discuss evolutionary events led transition from self-compatibility (SC).
