LEAFY COTYLEDON1 expression in the endosperm enables embryo maturation in Arabidopsis
Abstract
The LEC1 transcription factor is expressed in both embryo and endosperm during seed development. Here the authors show that LEC1 expression in the endosperm is necessary and sufficient for embryo maturation and that LEC1 protein is trafficked to the embryo to activate seed maturation.
