Exogenous melatonin enhances flooding tolerance in maize and is associated with coordinated redox, metabolic, and chloroplast responses.
Flooding stress (FS) at the maize seedling stage disrupts energy metabolism and redox homeostasis, impairing photosynthesis and causing cellular damage. This study evaluated whether exogenous melatonin (MT) alleviates FS injury in maize and characterized physiological and molecular responses associated with this protec...
