The endosperm is a seed tissue that supports the embryo. In most flowering plant species, the endosperm starts as a coenocyte that cellularizes after a defined number of mitotic divisions. We show that endosperm cellularization is under antagonistic parental control mediated by a family of maternally expressed auxin response factors.
