Reactive oxygen species (ROS) are important regulating factors that play a dual role in plant and human cells. As the first messenger response organisms, ROS coordinate signals growth, development, metabolic activity pathways. They also can act as an alarm mechanism, triggering cellular responses to harmful stimuli. However, excess cause oxidative stress-related damage oxidize organic substances, leading malfunctions. This review summarizes current research status mechanisms of eukaryotic cells, highlighting differences similarities between two elucidating their interactions with other reactive substances ROS. Based on similar regulatory pathways kingdoms, this proposes future developments provide opportunities develop novel strategies for treating diseases or creating greater agricultural value.

Cold stress is an effective factor in reducing production and injuring fruit trees. Various materials, such as salicylic acid, ascorbic putrescine, are used to alleviate the damage of abiotic stress.The effect different treatments acid on alleviating frost (- 3 °C) grapes 'Giziluzum' was investigated. Frost increased amount H2O2, MDA, proline, MSI. On other hand, it decreased concentration chlorophyll carotenoids leaves. Putrescine, significantly activities catalase, guaiacol peroxidase, ascorbate superoxide dismutase under stress. Following stress, treated with showed higher levels DHA, AsA, AsA/DHA than untreated grapes. Our results that treatment outperformed adjusting damages.The use compounds, ac id, modulates effects thereby increasing antioxidant defense system cells, its damage, stabilizing stable cell conditions, so can be reduce grape cultivars.

Predicting and optimizing reactive oxygen species metabolism in Punica granatum L. through machine learning: role of exogenous GABA on antioxidant enzyme activity under drought and salinity stress

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

Published: Jan. 23, 2024

Abstract Background Drought and salinity stress have been proposed as the main environmental factors threatening food security, they adversely affect crops' agricultural productivity. As a potential solution, application of plant growth regulators to enhance drought tolerance has gained considerable attention. γ-aminobutyric acid (GABA) is four-carbon non-protein amino that accumulates in plants response stressful conditions. This study focused on comparative assessment several machine learning (ML) regression models, including radial basis function, generalized neural network (GRNN), random forest (RF), support vector (SVR) develop predictive models for assessing effect different concentrations GABA (0, 10, 20, 40 mM) various physio-biochemical traits during periods drought, salinity, combined The included antioxidant enzyme activities (superoxide dismutase, SOD; peroxidase, POD; catalase, CAT; ascorbate APX), protein content, malondialdehyde (MDA) levels, hydrogen peroxide (H 2 O ) levels. non‑dominated sorting genetic algorithm‑II (NSGA‑II) was employed optimizing superior prediction model. Results GRNN model outperformed other ML algorithms therefore selected optimization by NSGA-II.

The Role of Foliar-Applied Silicon in Improving the Growth and Productivity of Early Potatoes

Agriculture, Journal Year: 2025, Volume and Issue: 15(5), P. 556 - 556

Published: March 5, 2025

Climate change is leading to a decline in global potato production. To ensure food security, it essential adapt cultivation practices the changing climate. The effects of foliar-applied silicon on growth and productivity under various hydrothermal conditions were investigated. Potato plants treated with three Si-based biostimulants: Actisil (6 g Si 20 Ca per liter; choline-stabilized orthosilicic acid; Chol-sSa + Ca); Krzemix ammonium metasilicate; Chol-sNH4-Sil); Optysil (93 24 Fe sodium metasilicate iron chelate Fe-EDTA; Na-Sil Fe-EDTA). Biostimulants twice, at leaf development stage (BBCH 13–15) two weeks after first treatment, 0.5 L/ha each treatment. biostimulants taller produced greater above-ground biomass higher tuber weight than control (without biostimulant). As result, total yield was higher, average, by 10% 13% marketable 11% 15%. plant-growth-promoting yield-increasing depended during growth. Chol-sSA (Actisil) applications most effective. Fe-EDTA (Optysil) better results warm very dry year, while Chol-sNH4-Sil (Krzemix) effective colder years periodic water deficit. Silicon foliar application can be new method for increasing early crop yields shortage conditions.

Nitrogen (N) is an important macro-nutrient required for crop production and considered commodity agricultural systems. Urea a vital source of N that used widely across the globe to meet requirements. However, applied in form urea mostly lost soil, posing serious economic environmental issues. Therefore, different approaches such as application coated with substances are worldwide reduce losses. coating imperative approach enhance corresponding nitrogen losses along its impact on environment. In addition, given food security challenges meeting current future demands food, best management strategy have led methods involve nutrients sulfur (S) zinc (Zn). Coated has slow-release mechanism remains soil longer period demand plants increases use efficiency, growth, yield, grain quality. These nutrient-coated (volatilization, leaching, 2 O) save environment from degradation. Sulfur zinc-coated also nutrient deficiencies synergetic effects other macro micronutrients crop. This study discusses dynamics their production, efficiency (NUE), residual toxic urea, constraints adopting fertilizers. Additionally, we shed light agronomic molecular NUE better productivity challenges.

Lime is an important commercial product in tropical and subtropical regions, where drought stress becoming one of the most severe environmental challenges agricultural sector. Melatonin antioxidant molecule that helps plants regulate their development respond to a variety stresses. In this research, effects exogenous melatonin treatments were evaluated at different concentrations (0, 50, 100, 150 μM) on biochemical aspects gene expression two species lime (“Mexican lime” “Persian lime”) under normal (100% field capacity (FC)) conditions (75% 40% FC). The experiments factorial based completely randomized design (CRD) with four replicates. Drought caused electrolyte leakage (EL) as well accumulations hydrogen peroxide (H2O2) malondialdehyde (MDA), indicating occurrence damage cellular membranes. contrast, pretreatment various reduced levels EL, H2O2 MDA while mitigating negative species. application (100-μM) significantly increased level proline content activity enzymes compared control plants. According real-time PCR analysis, treatment enhanced genes involved ROS scavenging, biosynthesis, cell redox regulation both species, respective controls. these findings, able detoxify systems, thereby protecting from stress-induced damages.
