title: A Female Identity Switch Helps Keep Only One Egg in the Basket.
abstract: The flowering plant female gametophyte carries two gametes, an egg cell and a central cell, whose double fertilization gives rise to embryo and endosperm, respectively. In this issue of Developmental Cell, Yuan et al. (2016) identify the protein CKI1 as a key switch that controls the differential female gamete identities.
