Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(1)

Published: Jan. 1, 2025

Heavy metal pollution, especially arsenic toxicity, significantly impairs plant growth and development. Phenolic acids, known for their antioxidant properties involvement in stress signaling, are gaining increased attention as secondary metabolites with the potential to enhance resistance these stressors. This study aimed investigate effects of different concentrations syringic acid (SA1, 10 μM; SA2, 250 SA3, 500 μM) on growth, photosynthetic parameters, activity lettuce seedlings subjected (As, 100 μM). Arsenic reduced by 56.7%, water content 7.39%, osmotic 26.2% leaves compared control. Conversely, SA1 SA2 treatments mitigated adverse preserved balance plants. However, SA3 treatment led a decrease 18.9% 39.5% As+SA3 groups, respectively, indicating that high-dose SA adversely affected under both control conditions. Exogenous improved photosynthesis, whereas provided milder benefits did not reduce exposure. H2O2 47.3% lipid peroxidation 33.4% seedlings. effectively oxidative enhancing activities key enzymes, such superoxide dismutase (SOD) peroxidase (POX). Moreover, was successful maintaining glutathione (GSH) pool, primarily promoted ascorbate (AsA) regeneration. In conclusion, μM (SA1) identified optimal dose reducing supporting growth. Overall, findings underscore resilience heavy toxicity.

Regeneration represents a fundamental biological process wherein an organism's tissues or organs repair and replace themselves following damage environmental stress. In plant systems, injured tree branches can regenerate adventitious buds develop new crowns through propagation techniques like cuttings canopy pruning, while transgenic plants emerge via tissue culture in genetic engineering processes intimately connected to regeneration mechanisms. The advancement of technology is critical for addressing complex dynamic climate challenges, ultimately ensuring global agricultural sustainability. This review comprehensively synthesizes the latest transformation technologies, including systems across woody, herbaceous algal species, organellar modifications, crucial factors facilitating Agrobacterium-mediated transformations, intricate hormonal networks regulating regeneration, comparative analyses transient approaches marker gene dynamics throughout processes. Ultimately, offers novel perspectives on current bottlenecks proposes future research trajectories.

Nano-Selenium and Glutathione Enhance Cucumber Resistance to Botrytis cinerea by Promoting Jasmonic Acid-Mediated Cucurbitacin Biosynthesis

ACS Nano, Journal Year: 2024, Volume and Issue: 18(31), P. 20576 - 20590

Published: July 24, 2024

Nano-selenium (Nano-Se), as a biological stimulant, promotes plant growth and development, well defense against biotic abiotic stresses. Glutathione (GSH) is crucial antioxidant also involved in the response to various In this study, efficacy of combined treatment Nano-Se GSH (SeG) on resistance cucumber plants Botrytis cinerea was investigated terms phenotype, gene expression, levels accumulated metabolites using transcriptomic metabolomic analyses. The exogenous application SeG significantly enhanced increased photosynthetic pigment contents capacity. Notably, B. infection reduced markedly by 41.9% after treatment. At molecular level, activated alpha-linolenic acid metabolic pathway upregulated expression genes responsible for jasmonic (JA) synthesis, including LOX (210%), LOX4 (430%), AOS1 (100%), AOC2 (120%), therefore promoting JA accumulation cucumber. Intriguingly, level cucurbitacin, an important phytoalexin cucurbitaceous plants, found be SeG-treated cucurbitacin biosynthesis-related OSC (107.5%), P450 (440.8%,31.6%), ACT (414.0%). These were treatment, suggesting that may upstream regulator biosynthesis. Taken together, study demonstrated pretreatment with could activate signaling promote biosynthesis enhance infection. findings indicate promising biostimulant protecting from without loss.

Physiological and metabolome characterization of Amaranthus hybridus L. grown under cypermethrin stress: an insight of Jasmonic acid treatment

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

Published: Feb. 1, 2025

The indiscriminate use of pesticides compromises physiology and metabolism in crops, posing health risks through residue accumulation edible tissues. Amaranthus hybridus L., a fast growing, nutritionally medicinally valuable crop was studied here to assess the impact cypermethrin (CYP) at recommended (R1, 100 ppm) double dose (R2, 200 alongside foliar application jasmonic acid (JA) 50 µM, µM concentrations. CYP R1 induced hormesis, while R2 toxic, elevating production ROS molecules (H2O2, SOR, MDA). JA upregulated antioxidant activity SOD, POD, APX, GST, DHAR, GSH, proline alleviate oxidative stress improve growth indicators, including shoot length, leaf area, chlorophyll content, Fv/Fm ratio, biomass. yielded highest increase biomass, 11.52% 13.7% for treated plants, respectively also led reduced residues. UHPLC-MS analysis tissue revealed contents carotenoids, flavonoids, phenolics, phenylpropanoids, steroids content plant group combinedly with compared those alone, indicating protective growth-promoting role under pesticide conditions. Overall, concentration proved be effective against by either study. These insights could offer strategies reduce pesticide-induced damage vegetable advancing sustainable agriculture.
