Plant biology: A social stigma

Teh-hui Kao1 & Andrew G. McCubbin1

In many bisexual flowering plants, the close proximity of male and female reproductive organs has resulted in the development of strategies to prevent inbreeding. One strategy, called self-incompatibility, enables the pistil (female) tissue to distinguish between self (genetically related) and non-self (genetically unrelated) pollen.
