Incompatibility in Plants

In this article we will discuss about:- 1. Recognition and Rejection of Incompatibility 2. Biological Significance of Incompatibility. Recognition and Rejection of Incompatibility: The rejection of 'self’ in self-incompatibility system implies the existence of a recognition event. In fact pollen-stigma interaction is an interesting example of cell recognition in flowering plants. Both self-and cross-pollinations are the outcome of such interactions [...]
