DESCRIPTION:Plants are expert architects that control cell proliferation a
 nd differentiation with exquisite spatiotemporal resolution to produce a d
 iversity of shapes and forms. The colourful patterns on the petals of flow
 ering plants perfectly illustrate their engineering skills. These patterns
  are also functionally relevant: they can protect pollen grains from UV ra
 diation and act as communication devices to attract pollinators. Petal pat
 terns are often highly elaborated and combine differences in pigmentation\
 , cell shape and texture to generate neighbouring tissues with distinct ap
 pearances. However\, the mechanisms used to program cell behaviour in a co
 ordinated fashion across the epidermis of a developing petal are not well 
 understood. I will present some results our group obtained while investiga
 ting pattern formation and evolution across a small group of Hibiscus spec
 ies. Our results help us understand how plants can set-up boundaries withi
 n the petal epidermis and how evolution tinkers with these processes to ge
 nerate the diversity of patterns observed in nature.
