Iron oxide nanoparticles enhance alkaline stress resilience in bell pepper by modulating photosynthetic capacity, membrane integrity, carbohydrate metabolism, and cellular antioxidant defense

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: Feb. 10, 2025

Bell pepper (Capsicum annuum L.) is a commercially important and nutritionally rich vegetable crop in the Solanaceae family. Alkaline stress (AS) can disrupt growth, metabolism, and, particularly, nutritional quality. This study aims to evaluate role of iron oxide nanoparticles (FeNP) mitigating AS enhancing plant growth metabolic functions by conducting experiments under controlled greenhouse conditions with four main treatments: (irrigating plants alkaline salts mixture solution); FeNP (foliar application Fe3O4 at 100 mg L−¹); + (integrated treatment FeNP); CK (control). The results clearly demonstrated that negatively affects biomass, photosynthetic attributes, membrane integrity, carbohydrate balance antioxidant system. Additionally, key phenolic flavonoid compounds decreased AS, indicating detrimental effect on plant's secondary metabolites. In contrast, not only improved attributes but also enhanced integrity restored balance. restoration was driven accumulation sugars (glucose, fructose, sucrose) starch, along metabolism enzymes—sucrose phosphate synthase (SPS), sucrose (SuSy), neutral invertase (NI), vacuolar (VI)—and their associated gene expression. correlation analysis further revealed tight regulation both enzymatic transcript levels all tissue types, except for SPS roots. Furthermore, resulted increased phenolics (dihydrocapsaicin, capsaicin, p-coumaric acid, sinapic p-OH benzoic benzaldehyde, ferulic acid) (dihydroquercetin, naringenin, kaempferol, dihydrokaempferol, quercetin) compared treatment, thus suggesting these metabolites likely contribute stabilization cellular structures membranes, ultimately supporting physiological resilience stress. conclusion, demonstrate potential bell against improving

Insights into trehalose mediated physiological and biochemical mechanisms in Zea mays L. under chromium stress

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: Aug. 17, 2024

Chromium (Cr) toxicity significantly threatens agricultural ecosystems worldwide, adversely affecting plant growth and development reducing crop productivity. Trehalose, a non-reducing sugar has been identified as mitigator of toxic effects induced by abiotic stressors such drought, salinity, heavy metals. The primary objective this study was to investigate the influence exogenously applied trehalose on maize plants exposed Cr stress. Two varieties, FH-1046 FH-1453, were subjected two different concentrations (0.3 mM, 0.5 mM). results revealed significant variations in biochemical parameters for both varieties under Cr-induced stress conditions compared control group. Foliar application at concentration 30 mM administered leading noteworthy reduction detrimental Notably, (0.5 mM) more affected shoot length than 0.3mM reduced 12.4% 24.5% FH-1453 while Trehalose increased 30.19% 4.75% respectively. constrained processes, whereas notably improved uptake minimizing oxidative caused Cr.

The present study investigates the impact of varying concentrations PVC microplastics (PVC–MPs) – specifically 0 (no PVC–MPs), 2, and 4 mg L− 1 –alongside different arsenic (As) levels As), 150, 300 kg− in soil, with concurrent application copper oxide–nanoparticles (CuO–NPs) at CuO –NPs), 25 50 µg mL− to barley (Hordeum vulgare L.) plants. This research primarily aims assess plant growth biomass, photosynthetic pigments gas exchange characteristics, oxidative stress indicators, as well response various antioxidants (both enzymatic non-enzymatic) their relevant genes expression, proline metabolism, AsA–GSH cycle, cellular fractionation within findings showed that increased PVC–MPs As soil significantly reduced pigments, characteristics. Additionally, roots shoots, evidenced by elevated malondialdehyde (MDA), hydrogen peroxide (H2O2), electrolyte leakage (EL), which turn stimulated production non-enzymatic antioxidants, gene sugar content. Furthermore, a notable increase pigmentation was observed. Conversely, CuO–NPs resulted substantial improvement activity along reduction stress. enhanced while decreasing metabolism AsA-GSH cycle H.
