Background: Pollen–pistil interactions are an essential prelude to fertilization in angiosperms and determine compatibility/incompatibility. Pollen–pistil interactions have been studied at a molecular and cellular level in relatively few families. Self- incompatibility (SI) is the best understood pollen–pistil interaction at a molecular level where three different molecular mechanisms...
