Catalase (CAT) is a crucial enzyme to control the excess peroxisomal H 2 O 2 produced during photorespiration. In many plant species, this enzymatic activity decreases in response to drought but its specific role in photosynthesis and redox metabolism is still poorly understood. In this study was te...
