Melatonin Mediated Enhancement of Photosynthetic Efficiency and Antioxidant Activity under Drought Stress

Yashwant Sompura, Garishma Shah, Upma Bhatt, Vineet Soni*

Abiotic environmental stresses and global climate change have a harsh impact on morphological, physiological, and biochemical characteristics of plants. Further, reduces the growth and development of plants. An indoleamine molecule called Melatonin (MLT) is important for plants' having ability to respond to a variety of abiotic stimuli and lessen their negative consequences. During harsh environmental conditions (such as draught, high temperature, high salinity, and heavy metal pollution), MLT significantly improves plant growth, photosynthetic yield, chlorophyll content, oxidative damage, and enhances the activity of anti-oxidant enzymes such as Superoxide Dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GOP). In this Review, we discuss that even though plants can biosynthesize MLT and exogenous application of MLT to a variety of crops can be enhance plant development and growth in response to drought stress by controlling the activity of antioxidant enzymes in the plants.
