In this study of hydroponically grown tomatoes, the authors reported that adding melatonin at 10-30 μmol·L-1 effectively enhanced lateral root development, root hair growth, biomass accumulation, and root activity by influencing related gene expression and hormone levels.
March 2025 in “International Journal of Molecular Sciences” This review explores melatonin's role in hair follicle cycles and its molecular mechanisms that enhance antioxidant capacity and modulate gene expression, offering potential strategies to improve cashmere production and treating human alopecia, according to the authors.
June 2026 in “New Phytologist” This study used multi-omics analysis to explore how wheat roots adapt to temperature stress, revealing that distinct hormonal signaling pathways are linked to iron homeostasis and drive root morphological changes, supporting the idea of an 'iron-dependent hormonal trade-off' model.
November 2024 in “Genomics” This study found that exogenous melatonin enhances the development of secondary hair follicles in Cashmere goats by promoting miRNA-mRNA interactions, specifically via the chi-let-7d-5p/WNT2 axis, which suggests a mechanism for melatonin's effects on hair growth involving microRNA regulation.
February 2025 in “Biomolecules” This research found that melatonin has a bidirectional effect on hair follicle stem cell survival, improving it at low doses and inhibiting it at high doses.
