Polycomb group proteins function in the female gametophyte to determine seed development in plants.

Development (Cambridge, England) - 1 Oct 2007

Leroy Olivier, Hennig Lars, Breuninger Holger, Laux Thomas, Köhler Claudia

Abstract excerpt

Polycomb group (PcG) proteins are evolutionary conserved proteins that stably maintain established transcriptional patterns over cell generations. The FERTILIZATION INDEPENDENT SEED (FIS) PcG complex from plants has a similar composition to the Polycomb repressive complex 2 from animals. Mutations in FIS genes cause parent-of-origin-dependent seed abortion. Every seed inheriting a mutant fis allele from the...
