A dialogue between the SIRENE pathway in synergids and the fertilization independent seed pathway in the central cell controls male gamete release during double fertilization in Arabidopsis.

Abstract excerpt

Angiosperms sexual reproduction involves interactions between the two female gametes in the embryo sac and the two male gametes released by the pollen tube. The two synergids of the embryo sac express the FERONIA/SIRENE receptor-like kinase, which controls the discharge of the two sperm cells from the pollen tube. FER/SRN may respond to a ligand from the pollen tube. Alternatively, the interaction between FER/SRN...
