Reactive oxygen species (ROS) signalling is crucial in plant responses to abiotic and biotic stresses. This Review discusses our current understanding of ROS regulation and sensing in plants, key regulatory hubs that connect ROS signalling with other stress-response pathways and how ROS signalling could be harnessed to increase plant resilience to environmental stress.
