During seed development the endosperm provides a nutritive function for the growing embryo, somewhat akin to the placenta in mammals, and is eventually consumed by the growing embryo. Thus endosperm is a major determinant of final seed size. However the genetic pathways controlling the breakdown and programmed cell death of the endosperm are little characterised. We identified a novel transcription factor, ZHOUPI (ZOU), which controls both the breakdown of the endosperm and also a signalling pathway between endosperm and embryo which mediates embryonic cuticle development. I will present the results from our genetic analysis of ZOU targets; we show that the two functions of ZOU in signalling to the embryo and endosperm cell death are genetically distinct. Secondly, I will present results from transcriptional profiling and functional characterization to identify novel targets mediating the cell death pathway
