DESCRIPTION:During seed development the endosperm provides a n
 utritive function for the growing embryo\, somewha
 t akin to the placenta in mammals\, and is eventua
 lly consumed by the growing embryo.  Thus endosper
 m is a major determinant of final seed size.  Howe
 ver the genetic pathways controlling the breakdown
  and programmed cell death of the endosperm are li
 ttle characterised.  We identified a novel transcr
 iption factor\, ZHOUPI (ZOU)\,  which controls bot
 h the breakdown of the endosperm and also a signal
 ling pathway between endosperm and embryo which me
 diates embryonic cuticle development.  I will pres
 ent the results from our genetic analysis of ZOU t
 argets\; we show that the two functions of ZOU in 
 signalling to the embryo and endosperm cell death 
 are genetically distinct.  Secondly\, I will prese
 nt results from transcriptional profiling and func
 tional characterization to identify novel targets 
 mediating the cell death pathway
