Enhancing drought tolerance in horticultural plants through plant hormones: a strategic coping mechanism

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 20, 2025

Abiotic stresses are considered as a significant factor restricting horticultural crop productivity and quality. Drought stress is major environmental constraint among the emerging concerns. Plants have susceptibility to drought stress, resulting in marked decline production during last several decades. The development of effective strategies mitigate essential for sustainable agriculture food security, especially considering continuous growth world population. Several studies suggested that exogenous application phytohormone plants can improve tolerance by activating molecular physiological defense systems. Phytohormone pretreatment potential approach alleviating plants. In addition, melatonin, salicylic acid, jasmonates, strigolactones, brassinosteroids, gamma-aminobutyric acid phytohormones function regulators effects stress. These hormones frequently interact with one another survival drought-stressed environments. To sum up, this review will predominantly elucidate role related mechanisms across various horticulture species.

Abstract In recent years, there has been an increase in the study of phytomelatonin. Having numerous functions animals, melatonin produced by plants (phytomelatonin) is also a multi‐regulatory molecule with great potential plant physiology and mitigating abiotic stresses, such as drought, salinity, chilling, heat, chemical contamination, UV‐radiation stress. This review highlights primary phytomelatonin anti‐stress against We discuss role master regulator, oxidative stress manager, reactive oxygen species nitrogen defense compounds inducer. Although exist handful reviews on crosstalk other signaling molecules like auxin, cytokinin, gibberellin, abscisic acid, ethylene, nitric oxide, jasmonic salicylic this looks at studies that have reported few aspects newly discovered along classical relation to tolerance. The research applications hydrogen sulfide, strigolactones, brassinosteroids, polyamines are still their nascent stage but hold promising scope for future. Additionally, states developments metabolism nitrosative plants.

Melatonin-governed growth and metabolome divergence: Circadian and stress responses in key plant species

Plant Physiology and Biochemistry, Journal Year: 2025, Volume and Issue: 221, P. 109635 - 109635

Published: Feb. 10, 2025

Melatonin, a versatile biomolecule, profoundly influences plant growth and resilience through its intricate regulation of metabolic pathways, circadian rhythms, cellular processes. The current study elucidates melatonin's concentration-dependent biphasic effects on dynamics in Arabidopsis thaliana Brassica nigra. While 50 μM melatonin optimized biomass accumulation root elongation, higher concentrations (100 μM) elicited stress responses, underscoring dual role as promoter modulator. Melatonin extended photosynthetic efficiency by modulating chlorophyll carotenoid synthesis diurnally, offering protection against photodamage. Divergent responses between the two species, driven species-specific reprogramming, were evident pigment biosynthesis antioxidant pathways. B. nigra displayed robust activation flavonoid phenylpropanoid cytokinin signaling, enhanced oxidative defenses, contrasting with A. thaliana, where suppressed precursors activation. Metabolomic analysis revealed orchestration hormonal crosstalk, involving auxins, gibberellins, jasmonates, to fine-tune adaptation. Stomatal cell wall fortification highlighted optimizing water-use structural under abiotic stress. Cytogenetic studies confirmed safeguarding genomic integrity, regulating chromatin remodeling, promoting DNA repair mechanisms, demonstrating adaptive strategies Moreover, influenced critical including polyamine biosynthesis, sulfur metabolism, nucleotide regulation, emphasizing multifaceted impact homeostasis. These findings position cornerstone molecule biotechnology, potential applications enhancing crop productivity fluctuating environmental conditions.
