Melatonin Improves Drought Stress Tolerance of Tomato by Modulating Plant Growth, Root Architecture, Photosynthesis, and Antioxidant Defense System

Verified

Muhammad Ahsan Altaf, Rabia Shahid, Ming‐Xun Ren, Safina Naz et al.

Journal: AntioxidantsYear: 2022Citations: 319

Tomato is an important vegetable that is highly sensitive to drought (DR) stress which impairs the development of tomato seedlings. Recently, melatonin (ME) has emerged as a nontoxic, regulatory biomolecule that regulates plant growth and enhances the DR tolerance mechanism in plants. The present st...

Melatonin plays multifunctional role in horticultural crops against environmental stresses: A review

Verified

Santosh Kumar Bose, Prianka Howlader

Journal: Environmental and Experimental BotanyYear: 2020Citations: 129

Melatonin (N-acetyl-5-methoxytryptamine) is a multifunctional nontoxic signaling molecule, universally distributed in different plant organs and accountable for invigorating numerous physiological mechanisms against various adverse environmental factors. In the current review, we revealed that the b...
