The below mentioned article provides a note on pollen-pistil interaction. It is an essential step of fertilisation of angiosperms. It determines compatibility and incompatibility. This interaction have been studied at a molecular and cellular level in relatively few families. It is a dynamic process involving pollen recognition followed by inhibition or promotion of pollen. The […]
