Review: Exocyst, exosomes, and autophagy in pollen-stigma interactions ($)
Some plants are able to suppress inbreeding through a system called self-incompatibility, in which “self”-pollen is unable to reach “self” eggs. Self-incompatibility has evolved multiple times and takes several forms. Goring reviews the cellular processes of self-incompatibility that occur in Brassicaseae in pollen-stigma interactions, the “first checkpoint in pollen selection”. Pollen coat proteins are involved […]
