Exogenous melatonin improves flooding tolerance in maize seedlings by 18.24%, linked to coordinated redox, metabolic, and chloroplast responses across multiple biological layers.
- Why it matters: Flooding stress severely disrupts maize energy metabolism and redox balance, impairing photosynthesis and causing cellular damage, which threatens crop yields and food security.
- What they did: The study applied exogenous melatonin to maize seedlings under flooding conditions and used transcriptomic, metabolomic, and hormone profiling to analyze physiological and molecular responses.
- The result: Melatonin treatment enhanced photosynthesis, water content, and antioxidant enzyme activities, reduced oxidative damage, improved chloroplast structure, and increased grain yield, indicating a comprehensive stress-alleviation effect.
