Self-Incompatibility in Plants | Genetics

In this article we will discuss about the self-incompatibility in plants. Sometimes bisexual plants produce functional male and female gametes, yet self-pollination does not lead to fertilisation and there is no seed setting. The pollen grains may fail to germinate on the stigma; or, even if pollen tubes are formed their growth may be inhibited. Such a condition where pollen [...]

Self Incompatibility in Plants | Palynology

In this article we will discuss about:- 1. Meaning of Self-Incompatibility 2. Molecular Basis 3. Determinants 4. Significance. Meaning of Self-Incompatibility: Self-incompatibility or intraspecific incompatibility is a well-designed genetic mechanism by which certain plants recognize and reject their own pollen thus forcing outbreeding. It is defined as "inability of the plant producing functional gametes to set seed upon self-pollination",. Lundqvist [...]
