GAUT10 is an enzyme required for pectin biosynthesis with established roles in root growth (Pu et al., 2019) and stomatal development (Guo et al., 2021). We are investigating how GAUT10 influences auxin homestasis, cell elongation, and cell division during root morphogenesis using genetics, live-cell microscopy, and biochemical approaches (Dash et al., bioRxiv 2023) in collaboration with Olga Zabotina. We are also studying protein properties of GAUT10 to determine how it is regulated by auxin posttranscriptionally (Pu et al., 2019) and how it contributes to cell wall dynamics.
