Researchers identify CAIR1 as a redox-responsive regulator that promotes catalase localization and activity, helping plants maintain hydrogen peroxide balance and cellular redox homeostasis.

A long-standing mystery about a pathway that makes a key defence molecule in various valuable crop plants is finally solved.

Much remains to be discovered about how the complex plant antioxidant network interacts to determine the outcome of oxidative stress, a central factor in plant responses to the environment. This work...
