Molecular basis of self-incompatibility in vegetable crops

Abstract

Molecular basis of self incompatibility system in vegetable crops Self incompatibility is an important out breeding mechanism results due to morphological, genetic, physiological and bio chemical causes. So far it has been reported in about 70 families of angiosperms including several crop species. The common way of plants to avoid self fertilization is by self incompatibility. It is a physiological barrier making the flower difficult to fertilize itself even though it may be abundantly pollinated with its own pollen. There are two forms of self incompatibility system includes sporophytic self incompatibility and gametophytic self incompatibility. Sporophytic self Incompatibility system is a feature of crucifer family (Brassicaceae). In this review, we discuss the self incompatibility system in molecular level, its practical application and suppression and its impact in vegetable crops.
