The paper develops a multiscale model to explain how GA4 synthesis, diffusion, and catabolism create a spatial gradient in Arabidopsis root growth zones, influencing cell elongation.

This study identifies GA2OX6 and GA2OX8 as key mediators of auxin-gibberellin crosstalk in Arabidopsis root growth, showing their roles in cell elongation and tissue organization.

The paper introduces Highlighter, a synthetic optogenetic system for precise light-mediated gene expression control in plants, demonstrating spatiotemporal regulation of gene expression and plant immunity.
