Angiosperm seed development is an intricate process involving three organs with distinct genetic makeup: the diploid zygotic embryo, the triploid zygotic endosperm, and the diploid maternal seed coat. Situated in between the embryo and the seed coat, the endosperm plays an important role in nutrient supply and growth coordination. Our lab is interested in the molecular mechanisms that regulate early endosperm development in Arabidopsis. Using genetic and molecular approaches, we are currently investigating the genes responsible for growth coordination between the embryo and the endosperm. Results from these studies have the potential to reveal how neighboring organs influence each other’s developmental program in the seed. Moreover, this knowledge can be applied to agricultural improvement, since cereal endosperm constitutes a significant portion of the human diet.
