Melatonin-Induced Transcriptome Variation of Sweet Potato Under Heat Stress

Plants, Journal Year: 2025, Volume and Issue: 14(3), P. 430 - 430

Melatonin (MT) has been widely recognized for its ability to mitigate the effects of abiotic stress and regulate plant development. In this study, we investigated role exogenous MT in enhancing heat tolerance sweet potato, with a particular focus on capacity alleviate stress-induced damage. treatment significantly reduced oxidative stress, as evidenced by decreased levels hydrogen peroxide, superoxide ions, malondialdehyde (MDA), all which were elevated under stress. To uncover underlying mechanisms, RNA sequencing was performed three experimental groups: control (CK), alone (HS), pre-treatment followed (MH). A total 3491, 3280, 1171 differentially expressed genes (DEGs) identified CK vs. HS, MH, HS MH comparisons, respectively. notably modulated expression involved redox regulation nicotinate nicotinamide metabolism. Moreover, enhanced associated key signaling pathways, including mitogen-activated protein kinases (MPK3) hormone signal transduction components, such ethylene response factor (ERF). These findings offer novel insights into mechanisms enhances highlighting regulating antioxidant systems, metabolic signaling. This study presents valuable strategies improving crop resilience

Glycomolecules: from “sweet immunity” to “sweet biostimulation”?

Physiologia Plantarum, Journal Year: 2024, Volume and Issue: 176(6)

Climate changes and environmental contaminants are daunting challenges that require an urgent change from current agricultural practices to sustainable agriculture. Biostimulants natural solutions adhere the principles of organic farming believed have low impacts on environment human health. Further, they may contribute reducing use chemical inputs while maintaining productivity in adverse environments. generally defined as formulated substances microorganisms showing benefits for plant growth, yield, rhizosphere function, nutrient-use efficiency, quality harvested products, or abiotic stress tolerance. These biosolutions categorized different subclasses. Several them enriched glycomolecules their oligomers. However, very few studies considered active molecules biostimulation a subclass own. Herein, we describe structure functions complex polysaccharides, glycoproteins, glycolipids relation defense biostimulation. We also discuss parallels between sugar-enhanced with introduce concept sweet glycostimulation.
