... autonomous signalling Polycomb group protein seed coat seed development The evolutionary success of angiosperms is closely connected to the occurrence of double fertilization and the formation of seeds containing two fertilization products: the embryo and the endosperm. The endosperm is a terminal...

..., with each having a distinct genetic composition which exerts different influences on seed development. Complex cross-talk and integration of signals from these different regions of the seed together determine its final size. The present review considers some of the major regulators of seed size...

.... The two tissues surrounding the embryo, the endosperm and the integuments, have specialized roles to fulfil these functions. The endosperm is involved in nurturing the embryo during the different stages of seed development. In addition, the endosperm contributes to other seed developmental processes, e.g...
