DESCRIPTION:During seed development the endosperm provides a nutritive fun
 ction for the growing embryo\, somewhat akin to the placenta in mammals\, 
 and is eventually consumed by the growing embryo.  Thus endosperm is a maj
 or determinant of final seed size.  However the genetic pathways controlli
 ng the breakdown and programmed cell death of the endosperm are little cha
 racterised.  We identified a novel transcription factor\, ZHOUPI (ZOU)\,  
 which controls both the breakdown of the endosperm and also a signalling p
 athway between endosperm and embryo which mediates embryonic cuticle devel
 opment.  I will present the results from our genetic analysis of ZOU targe
 ts\; 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
