TL;DR: Grossniklaus et al. as mentioned in this paper used a map-based strategy to identify a mutation in Arabidopsis, f644, that allows for replication of the central cell and subsequent endosperm development without fertilization.

TL;DR: Cloned and sequenced the F644 gene and showed that it encodes a SET-domain polycomb protein, and found that F644 is identical to MEDEA (MEA), a gene whose maternal-derived allele is required for embryogenesis.

TL;DR: It is shown that FIE and MEA polycomb proteins interact physically, suggesting that the molecular partnership of WD and SET domainpolycomb proteins has been conserved during the evolution of flowering plants.

TL;DR: Results suggest that FIE may inhibit premature division of the central cell of the embryo sac, at least partly, through interaction with pRb, and suppression of pRB-regulated genes.

TL;DR: The results show that mechanical stimulation brought about an increase in the root branching, and components of the response mechanism to short and long term mechanical simulation of tomato root apices were identified at the morphological and molecular level.
