Project: Central cell fertilization and endosperm development in Arabidopsis

Project Summary:

Glauce, is a female gametophyte mutant published recently by the Sundar lab, in which the embryo develops up to the globular stage with no endosperm formation. GLAUCE molecular identity as well as other fundamental issues of this mutant are being investigated.
