Abstract 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 by promoting outcrossing and avoiding inbreeding. For thousands of years, this trait has been effectively exploited by breeders and growers as a tool to manipulate domesticated crops. However, efforts to spell out the molecular features of SI have begun only during the past thirty years. For breeders that need to produce homozygous lines, SI is undesirable. Moreover, in fruit crops, SI hinders the production of true to type plants and high-quality fruits with uniform traits because SI favors outcrossing. Numerous techniques have been developed to break down SI. Here, we review the current understanding of different molecular SI systems and pinpoint different physiological and molecular techniques used to break down SI. We also discuss evolutionary events that led to the transition from SI to self-compatibility (SC).
期刊介绍:
Critical Reviews in Plant Sciences focuses on presenting in-depth and up-to-date reviews of timely and/or cutting-edge subjects in the broad discipline of plant science, ranging from molecular biology/biochemistry through the areas of cell biology, plant pathology and physiology, genetics, classical botany, and ecology, to practical agricultural applications. Articles in the journal provide an up-to-date literature base for researchers and students, pointing the way towards future research needs. The journal is also a significant source of credible, objective information to aid decision makers at all levels.
