Reactive oxygen species (ROS) are essential for life and involved in the regulation of almost all biological processes. ROS production is critical for plant development, response to abiotic stresses, and immune responses. ROS can also cause direct oxidative damage and organisms must therefore balance ROS production and quenching. Here, we focus on recent discoveries in ROS biology emphasizing abiotic and biotic stress responses. Recent advancements have resulted in the identification of one of the first sensors for extracellular ROS and highlighted waves of ROS production during stress signaling in Arabidopsis. Enzymes that produce ROS, including NADPH oxidases, exhibit precise regulation through diverse posttranslational modifications. Discoveries highlight the importance of both N- and C-terminal regulation of NADPH oxidases through protein phosphorylation and cysteine oxidation. Here, we discuss advancements in ROS compartmentalization, systemic ROS waves, ROS sensing, and posttranslational modification of ROS producing enzymes as well as identify areas where foundational gaps remain.
