Cell polarity in
Arabidopsis thaliana is intensively studied in polar auxin transport processes. Cell polarity of the PIN1 efflux carrier at the membrane is controlled by the PID kinase and the co-localized protein ENP. Analysis of ENP polarity revealed intrinsic and extrinsic factors, including new interaction partners, both required for ENPs correct localization, function and subcellular trafficking. The consequences of PIN1 polarity alteration on cotyledon development were assessed. The significance of boron for the interaction of proteins with membranes was studied using boron competitors.
