Abstract:

Polycomb-group (Pc-G) proteins repress their target gene expression by assemble complexes in Drosophila and mammals. Three groups of Pc-G genes, controlling seed development, flower development and vernalization response, have been identified in Arabidopsis (Arabidopsis thaliana L.). MEDEA (MEA), FERTILIZATION INDEPENDENT SEED2 (FIS2), and FERTILIZATION INDEPENDENT ENDOSPERM (FIE) are Pc-G genes in Arabidopsis. Their functions in seed development have been extensively explored. The advanced findings of molecular mechanism on how MEA, FIS2 and FIE control seed development in Arabidopsis are reviewed in this paper.
