Abstract To enhance selenium (Se) uptake in peach plants, a pot experiment was conducted to study the effects of melatonin (150 μmol/L) and 24‐epibrassinolide (1.5 mg/L) on growth Se accumulation wild (as rootstock peach) seedlings under stress (0.1 mg/L). The results showed that application melatonin, 24‐epibrassinolide, combination both increased biomass levels photosynthetic pigments (chlorophyll , chlorophyll b carotenoids) stress. Furthermore, these treatments activities peroxidase catalase while decreasing activity superoxide dismutase. Among treatments, only resulted an increase root content bioconcentration factor (BCF) seedlings. Compared treatment alone, with shoot by 40.87%, 53.91%, 53.04%, respectively, as well translocation factor, BCF, whole plant BCF Correlation gray relational analyses revealed carotenoid content, biomass, closest relationships Thus, can effectively promote stress, best observed 24‐epibrassinolide.

Selenium improves wheat antioxidant capacity, photosynthetic capacity, and growth under cadmium stress

Photosynthetica, Год журнала: 2024, Номер 62(3), С. 232 - 239

Cadmium stress (CS) induced the peroxide damage and inhibited wheat photosynthetic capacity growth. Compared to CS, selenium (Se) application plus CS bolstered chlorophyll carotenoid contents, rate, maximum photochemical efficiency of PSII, quantum yield PSII photochemistry, quenching, superoxide dismutase, catalase, ascorbate peroxidase, glutathione reductase, L-galactono-1,4-lactone dehydrogenase, gamma-glutamylcysteine synthetase activities, ascorbic acid AsA/dehydroascorbic GSH/oxidized glutathione, decreased nonphotochemical quenching (q_N), antioxidant biomarkers malondialdehyde hydrogen electrolyte leakage (EL). At same time, Se alone declined q_N EL, augmented rest aforementioned indexes. Our research implied that upregulated wheat's capacity. In this way, improved performance growth, especially for 10 μM sodium selenite (Na₂SeO₃). Consequently, Na₂SeO₃ may be considered a useful exogenous substance reinforce cadmium tolerance.

γ-aminobutyric acid enhances the antioxidant defense system and photosynthetic performance of wheat seedlings under cadmium stress

Plant Soil and Environment, Год журнала: 2024, Номер 70(9), С. 590 - 599

Опубликована: Авг. 6, 2024

In this paper, I elucidated the influence of γ-aminobutyric acid (GABA) on wheat cadmium (Cd) tolerance. Research results manifested that Cd stress increased superoxide dismutase, catalase, peroxidase, ascorbate peroxidase and glutathione activities, ascorbic (AsA) (GSH) contents. However, decreased AsA/ dehydroascorbic (DHA) GSH/oxidised (GSSG) ratios, inhibited photosynthetic performance plant growth. Compared to alone, GABA plus improved tolerance by increasing activities above antioxidant enzymes, AsA GSH contents, AsA/DHA GSH/GSSG ratios. Meanwhile, compared with also enhanced improving chlorophyll (Chl) carotenoid (Car) contents Car/Chl ratio, rate, transpiration stomatal conductance, intercellular carbon dioxide concentration, Chl fluorescence parameters maximum photochemical efficiency PSII, quenching, nonphotochemical quenching quantum PSII photochemistry, which further promoted height biomass. control, alone indicators. Current suggested can be applied as an anti-cadmium agent in production practice.

Melatonin Ameliorates Cadmium Toxicity in Tobacco Seedlings by Depriving Its Bioaccumulation, Enhancing Photosynthetic Activity and Antioxidant Gene Expression

Plants, Год журнала: 2024, Номер 13(21), С. 3049 - 3049

Опубликована: Окт. 31, 2024

Soil remediation for cadmium (Cd) toxicity is essential successful tobacco cultivation and production. Melatonin application can relieve heavy metal stress promote plant growth; however, it remains somewhat unclear whether melatonin supplementation remediate the effects of Cd on growth development seedlings. Herein, we evaluated effect soil-applied accumulation in seedlings, as well responses growth, physiological biochemical parameters, expression stress-responsive genes. Our results demonstrate that mitigated tobacco, thus promoted growth. It increased root fresh weight, dry shoot weight by 58.40%, 163.80%, 34.70% 84.09%, respectively, compared to control. Physiological analyses also showed significant differences photosynthetic rate pigment formation among treatments, with highest improvements recorded application. In addition, alleviated Cd-induced oxidative damage reducing MDA content enhancing activities enzymatic antioxidants (CAT, SOD, POD APX) non-enzymatic (GSH AsA). Moreover, confocal microscopic imaging confirmed effectiveness sustaining cell integrity under stress. Scanning Electron Microscopy (SEM) observations illustrated alleviative role stomata ultrastructural features toxicity. The qRT-PCR analysis revealed upregulated antioxidant-related genes, including

The resilience of tomato plants under different cultivation environments, particularly saline and non-saline conditions, was investigated by applying various treatments, including 0.5% Ascorbic Acid (AsA) 1% Sulphur-treated Biochar (BS). study evaluated parameters such as fruit length, diameter, yield per plant pot, Total Soluble Solids (TSS) content, chlorophyll electrolyte leakage, enzyme activities (Superoxide Dismutase - SOD, Peroxidase POD, Catalase CAT), nutrient content (Nitrogen N%, Phosphorus P%, Potassium K%). Under significant enhancements were observed in characteristics metrics with the application AsA BS individually, combined treatment yielding most substantial improvements. Notably, treatments exhibited varying effects on TSS levels, activities, combination consistently demonstrating superior outcomes. Additionally, analysis revealed notable increases, showcasing enhancements. Overall, underscores potential promoting resilience, offering insights into their synergistic multiple physiological biochemical crucial for growth productivity.
