Area of Interest
In my present research, I am collaborating with Dr, Gloria Muday on a study of the localization of the the auxin transport protein PIN2 in Arabidopsis. PIN2 is a member of a family of protein whose asymmetric localization in the plasma membrane determines the direction of polar auxin transport. PIN2, which is responsible for shootward transport of auxin, is localized on the apical surface of cortical cells in the root.
The polar localization of the PIN proteins is thought to occur through cycling of proteins between endosomes and the plasma membrane. In the Arabdidopsis mutant scd1-1, PIN2 is mislocalized, appearing not only on the apical surface of the cells but also in small vesicular structures throughout the cytoplasm. Using scd1-1 seeds crossed with PIN2-GFP and fluorescently-labeled markers of various endomembrane compartments, we are using the scd1-1 mutant to better understand intracellular trafficking of the PIN2 protein.
