DESCRIPTION:Gorteria diffusa\, a daisy endemic to northwest South Africa b
 elonging to the Asteraceae family exhibits a very distinct raised dark pet
 al-spot at the base of the subset of its ray florets. This dark petal-spot
  appears to mimic small bee flies (Megapalpus capensis) which pollinate G.
  diffusa. Field investigations showed that the dark spots induce mating be
 haviour in male flies.\n\nThe G. diffusa petal spot is a three-dimensional
  elaboration of the petal epidermis with three specialized oration cell ty
 pes. These specialized cell types must differentiate in the correct positi
 ons with respect to one another on the ligule to mimic the flies otherwise
  sexual deception does not occur.\n\nI will discuss my preliminary results
  on the ontogeny of ray floret development\, expression pattern of potenti
 al regulator of petal spot and the work plan to address how spot developme
 nt is coordinated between the petals forming a ligule.\n\n
