Abstract

The scaffolding protein RACK1 is involved in polar auxin transport and signaling. It binds to PINOID and PIN-FORMED2, enhancing their interaction and phosphorylation-dependent auxin efflux. Knocking down RACK1 genes impairs auxin-related processes such as root growth and gravitropic response.
