  1. Systems biology of plant cell polarity and leaf development Our team University of Freiburg Biologie II/Botanik ZBSA LMB AG Palme, Ditengou, Dovzhenko, Teale AG Fleck AG Ronneberger Industrial partners TILL Photonics

  2. Cellpolarityregulationisusedbysessileplants as a matter offlexible life style

  3. Polarityregulationallows flexible responses

  4. Polar auxintransportallows flexible adaptationofnewfunctions indole-3-acetic acid (IAA)

  5. The PIN auxin efflux facilitator proteins enable flexible redirection of auxin and enable local auxin accumulation Atpin1 wt pin1

  6. PIN proteinsaredynamicandloalized in microdomains • Characterization of polar auxin transporting micro-domains that orchestrate plant development. • How are they formed, how are they regulated ? • What is the functional auxin transport unit ? Auxin transporting microdomains

  7. Arabidopsis PIN proteins: markers of cell polarity Atpin1 • share features with major facilitor super family • have a size of about 50 to 60 kDa • cycle between PM-EE-MVB and other compartments • PIN microdomains are distinct from plasmodesmata wt pin1 BFA Latrunculin
