Arabidopsis ribosomal proteins control vacuole trafficking and developmental programs through the regulation of lipid metabolism.

Auxin is an important phytohormone that regulates almost all aspects of plant growth and development. Ribosome proteins serve as translational regulators of auxin response. This work highlights the significance of lipid metabolism in the downstream of ribosome protein function to link auxin-regulated developmental patterning with endomembrane trafficking. Our work sheds light on a novel link between auxin signaling, ribosome function, and lipid metabolism.
