Promoter-Level Regulation of Melatonin Biosynthesis in Plant Stress Responses: A Framework for Climate-Resilient Crop Improvement.
This review examines melatonin biosynthesis and function from a promoter-centered perspective, focusing on how stress-associated signals may regulate the core biosynthetic genes TDC, T5H, SNAT, and ASMT/COMT across tissues and stress contexts.
