Abstract Production of reactive oxygen species ( ROS ) by NADPH oxidases ( NOX s) impacts many processes in animals and plants, and many plant receptor pathways involve rapid, NOX ‐dependent increases of ROS . Yet, their general reactivity has made it challenging to pinpoint the precise role and immediate molecular action of ROS . A well‐understood ROS action in plants is to provide the co‐substrate for lignin peroxidases in the cell wall. Lignin can be deposited with exquisite spatial control, but the underlying mechanisms have remained elusive. Here, we establish a kinase signaling relay that exerts direct, spatial control over ROS production and lignification within the cell wall. We show that polar localization of a single kinase component is crucial for pathway function. Our data indicate that an intersection of more broadly localized components allows for micrometer‐scale precision of lignification and that this system is triggered through initiation of ROS production as a critical peroxidase co‐substrate.
