Summary The Arabidopsis FERTILIZATION‐INDEPENDENT ENDOSPERM (FIE) polycomb
group (PcG) protein, a WD40 homologue of Drosophila extra sex comb (ESC), regulates …

A fundamental problem in biology is to understand how fertilization initiates reproductive
development. Higher plant reproduction is unique because two fertilization events are …

In higher plants, developmental phase changes are regulated by a complex gene network.
Loss-of-function mutations in the EMBRYONIC FLOWER genes (EMF1 and EMF2) cause …

The Polycomb group (PcG) complex is involved in the epigenetic control of gene expression
profiles. In flowering plants, PcG proteins regulate vegetative and reproductive programs …

In Arabidopsis, a complex of Polycomb-group (PcG) proteins functions in the female
gametophyte to control the initiation of seed development. Mutations in the PcG genes …

In flowering plants, two cells are fertilized in the haploid female gametophyte. Egg and
sperm nuclei fuse to form the embryo. A second sperm nucleus fuses with the central cell …

In Arabidopsis, mutations in the Pc-G gene CURLY LEAF (CLF) give early flowering plants
with curled leaves. This phenotype is caused by mis-expression of the floral homeotic gene …

Transcriptional activators of the Trithorax group (TRX-G) and repressors of the Polycomb
group (Pc-G) are involved in multiple aspects of embryogenesis in Drosophila and the …

Genes of the FERTILISATION INDEPENDENT SEED (FIS) class regulate cell proliferation
during reproductive development in Arabidopsis [1–5]. The FIS genes FERTILISATION …

In Arabidopsis, the EMBYRONIC FLOWER2 (EMF2), VERNALISATION2 (VRN2) and
FERTILISATION INDEPENDENT ENDOSPERM2 (FIS2) genes encode related Polycomb …
