Function
Required for acclimation to reactive oxygen species (ROS) responses downstream of beta-cyclocitral (beta-cc) or mediated by dihydroactinidiolide, including singlet oxygen 1O(2) detoxification reactions, especially upon light-mediated photooxidative stress, and leading to programmed cell death (PubMed:24151292, PubMed:27813110). Prevents leaf senescence (PubMed:24151292). Involved in cold acclimation (PubMed:27813110).
