DESCRIPTION:Mobile signals provided by hormones and morphogens are essenti
 al to organise multicellular structures. Despite detailed knowledge on the
  dynamics of specific hormones in specific cellular environments\, not muc
 h is known about the interactions between different hormonal pathways or b
 etween hormonal and genetic events that lead to proper organ formation. Th
 e Arabidopsis fruit provides an outstanding model system to study organ pa
 tterning and cell differentiation with dramatically different cell types l
 ocated immediately next to each other. Work on Arabidopsis fruit developme
 nt has been impressively successful in identifying key genetic regulators\
 ; however\, the data clearly indicate that in order to get an integrated v
 iew of fruit patterning\, it is necessary to understand the role of hormon
 es in the process. We use Arabidopsis and Brassica fruits as models to stu
 dy how genetic and hormonal activities interact to form a complex organ. R
 esults will be presented on the importance of both local hormone biosynthe
 sis and distribution\, on communication between tissues to coordinate grow
 th and how these processes are controlled. \n\nhttp://www.jic.ac.uk/profil
