Synergistic effects of Vachellia nilotica-derived zinc oxide nanoparticles and melatonin on drought tolerance in Fragaria × ananassa

BMC Plant Biology, Год журнала: 2025, Номер 25(1)

Опубликована: Янв. 22, 2025

This study investigates the synergistic effects of zinc oxide nanoparticles (ZnO NPs) and melatonin (MT) on Fragaria × ananassa (strawberry) plants under drought stress, focusing growth, fruit biomass, stress tolerance. ZnO NPs enhance nutrient uptake resistance, while MT regulates growth hormones boosts photosynthetic efficiency. Seven treatments were evaluated: T1 (no 0.5 g/L + 0.1 MT), T2 NPs), T3 T4 (drought no application), T5 T6 T7 MT). Growth parameters included shoot/root length, bud number, chlorophyll content, oxidative markers (H₂O₂, MDA), antioxidant enzyme activities in leaves ananassa. The combined treatment MT) consistently outperformed others, achieving highest metrics both conditions: shoot length (22.33 ± 1.53 cm non-stress, 15.00 drought), root (18.67 12.00 biomass (9.55 0.31 g 5.02 0.23 drought). Bud formation peaked at 3.33 0.58 buds/plant non-stress 2.00 0.00 drought. Under drought, also enhanced content (2.47 0.20 mg/g FW) significantly reduced H₂O₂ (28.67 2.52 µmol/g MDA (4.21 0.10 levels, maximizing (SOD: 121.67 7.64 U/g FW, POD: 206.33 14.84 CAT: 48.00 3.61 FW). These findings highlight application as a promising strategy to tolerance strawberry plants, warranting further research optimized concentrations, delivery methods, molecular mechanisms.

Melatonin-Induced Transcriptome Variation of Sweet Potato Under Heat Stress

Plants, Год журнала: 2025, Номер 14(3), С. 430 - 430

Опубликована: Фев. 1, 2025

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

Combined Effect of Melatonin and Sulfur on Alleviating Waterlogging Stress in Rapeseed

Plant-Environment Interactions, Год журнала: 2025, Номер 6(2)

Опубликована: Март 27, 2025

ABSTRACT Melatonin, a multifunctional, non‐toxic regulatory molecule, plays crucial role in enhancing tolerance to abiotic stress, which is tightly linked S metabolism. Despite the proven efficacy of sulfur (S) stress tolerance, combined effect and melatonin mitigation remains be elucidated. This particularly relevant context climate change, where increased occurrence waterlogging increases risk reduced availability, leading yield quality rapeseed. The objective this study examine impact combination foliar sulfur, when administered soil or leaves, on response plants stress. experimental design involved supplementation rapeseed ( Brassica napus L.) with either (0.2 g kg −1 ) leaves (300 ppm) 5 days prior induction. were subjected at BBCH–31 for period 7 days, preceded by pretreatment 2 (200 μM). In comparison, untreated showed significant reduction growth, nutrient uptake, photosynthetic activity, sugar content but an increase antioxidant defense system. However, application significantly mitigated adverse effects comparison control, soil‐S exhibited higher than increasing plant resistance, as reflected improved dry weight (+50%), photosynthesis (+12%), stomatal conductance (+40%), magnesium (+59%), hydrogen peroxide (−22%) lipid peroxidase (−26%). also catalase (+43%), glutathione reductase (+17%), ascorbate (+47%), (+39%), (+40%) contents, contrast waterlogged plants. underlines potential effective agents alleviate

Transcriptome and metabolome analysis of the responses of salt resistance of different Helianthus annuus germplasms to melatonin

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Introduction Salt stress always causes irreversible damages to the growth of Helianthus annuus seedlings in arid and semi-arid areas due weakest salt resistance at seedling stage. Melatonin is a multifunctional molecule that can enhance several crops. However, effect melatonin on H. still unclear. Methods In this study, four germplasms with different (YE988, S2102, Longkuiza 4, 909S) were selected from total 164 China, France, Chili, Unit States, etc. Then, treatments for designed, including (1) CK, no + application; (2) MT, (3) K, (4) MK, application. After that, key genes metabolic pathways involved responses determined by transcriptome metabolome analysis. Results discussion The results showed there 530 differentially expressed (37 upregulated 493 down-regulated genes) leaves MK vs. these mainly fatty acids, diterpenoid biosynthesis, linolenic acid metabolism, cysteine methionine metabolism. There 60 abundant metabolites (17 up-regulated 43 downregulated metabolites) concentrating tryptophan biosynthesis amino secondary pathways. integrated analysis regulated b-alanine monoterpene glutathione metabolism pathways, increased contents spermine spermidine cells promoting expression such as HannXRQ_Chr07g0195521 HannXRQ_Chr03g0093321 pathway. summary, could signaling up-regulating related synthesis leaves, regulate photosynthesis reactive oxygen species ultimately enhancing . This study will advance understanding mechanism which enhances annuus, provide scientific basis breeding saltresistant cultivars.
