My current research focus: Dissecting the interplay of signaling molecules upstream of cell expansion (restriction/polar direction) in root epidermis/lateral root cap cells under carbon starvation. This includes tracking of signal molecule distribution by live cell imaging, and analysis of post-translational modification of key proteins involved in their distribution.
