|a Root system architecture depends on endogenous and environmental signals, including polar transport of the phytohormone auxin, reactive oxygen species (ROS), nutrient availability, and stresses. In our study, we describe a novel Arabidopsis thaliana peroxisome-localized copper amine oxidase ζ (CuAOζ), which is highly expressed in cortical cells, and the ROS derived from CuAOζ are essential for lateral root (LR) development. Loss of CuAOζ results in retarded auxin-induced ROS generation, PINFORMED2 (PIN2)-mediated auxin transport, and LR development in response to added indole-3-butyric acid. Auxins enhance CuAOζ protein levels and their cellular translocation toward the plasma membrane in the cortex. CuAOζ interacts physically with PEROXINS5 via an N-terminal signal tag, Ser-Lys-Leu, and is transported into the peroxisome upon this interaction, which is required for the functions of CuAOζ in the auxin response. Together, our results suggest a peroxisomal ROS-based auxin signaling pathway involving spatiotemporal-dependent CuAOζ functional regulation of PIN2 homeostasis, auxin distribution, and LR development
