Maternal control of embryogenesis by MEDEA, a polycomb group gene in Arabidopsis.

Science (New York, N.Y.) - 17 Apr 1998

Grossniklaus U, Vielle-Calzada J P, Hoeppner M A, Gagliano W B

Abstract excerpt

The gametophytic maternal effect mutant medea (mea) shows aberrant growth regulation during embryogenesis in Arabidopsis thaliana. Embryos derived from mea eggs grow excessively and die during seed desiccation. Embryo lethality is independent of the paternal contribution and gene dosage. The mea...
