Abstract Lignans are a prominent group of phenolic compounds ubiquitously present in the plant kingdom, playing a critical role in both plant physiology and human health. Structurally they are characterized by the dimerization of two phenylpropane units to attain diverse chemical configurations that contribute to their wide range of biological activities. In plants, lignans function primarily as defense molecules, protecting against pathogens, herbivores, and environmental stressors. These compounds also participate in plant growth regulation and lignification processes. From a nutritional and medicinal perspective, lignans are valued for their significant health benefits. They act as phytoestrogens,… More >

Abstract Entoloma clypeatum, a kind of edible ectomycorrhizal fungus, can be usually symbiotic with Rosaceae fruit trees. Fruit trees have become an important part of China’s agriculture. The present work focused on exploring how E. clypeatum affected symbiotic Rosaceae plants and establishing a symbiotic culture with Malus robusta, Pyrus betulifolia and Prunus armeniaca rootstocks. The results showed that E. clypeatum and three Rosaceae plants can generate cylindrical or clavate mycorrhizae. The inoculation treatment had different degrees of positive effects on the three plants. Relative to the non-inoculated group, biomass in symbiotic plants increased (32.8%–191.1%), and photosynthesis enhanced. In the level of… More >

Abstract Chitosan films with propolis aqueous extract were obtained in order to improve the antioxidant capacity of the materials. Likewise, oleic acid (OA) was also incorporated to enhance the film hydrophobicity, with and without previous infusion with propolis, to extract other potentially active compounds. The propolis extracts and the chitosan film-forming dispersions were characterised as to their particle size distribution, zeta potential and rheological behaviour. Chitosan-based films with aqueous extract and with oleic acid, containing or not propolis compounds, were obtained and characterised as to their microstructure, mechanical, barrier and optical properties and antioxidant capacity in… More > Graphic Abstract

Abstract Chilling is one of the major abiotic stresses for plants, especially for rice cultivation. Many essential metabolic processes for growth and development are temperature-dependent. In that case, reducing the negative effects of cold stress using exogenous chemicals is a possible option. Therefore, the current study examined the effects of pre-sowing seed treatment with different chemicals, viz. hydrogen peroxide (H₂O₂), salicylic acid (SA), calcium chloride (CaCl₂), thiourea (TU), and citric acid (CA) on the germination of rice seeds (cv. BRRI dhan28) under chilling environments. Rice seeds were soaked in distilled water (control), 10 mM CA, 2 mM SA,… More >

Abstract Globally, salinity is a brutal environmental constraint that poses a major threat to agriculture worldwide, causing nutrient imbalances and oxidative stress, leading to reduced crop yields and quality. Date palm waste from the agro-industry is a major environmental problem, but its conversion to biochar for soil amendment could help alleviate the effects of salinity stress. Pepper is a commonly grown horticultural crop that is sensitive to salinity. That’s why the current experiment was conducted with the novel idea of exploring the potential use of biochar-based fertilizer derived from date palm waste as a mitigation strategy… More >

Abstract Tannins are capable of producing natural dyes with antioxidant and antibacterial propertis, while synthetic dyes are commonly used in the textile industry, causing environmental issues like water pollution. This research aims to utilize waste tannins as natural dyes as an alternative to synthetic dyes. This study examined the effect of the extraction method on tannin properties such as phenolic content, antioxidants, and antibacterial activity. In addition, Pyrolysis Gas Chromatography‒Mass Spectrometry (Py-GCMS) analysis was used to identify the effect of extraction temperature on the chemical elucidation of tannin. The effect of tannin concentration was evaluated against… More > Graphic Abstract

Abstract Salinity is a major abiotic stress that hinders plant development and productivity and influences agricultural yield. Seed priming is a technique used to boost germination and seedling growth under abiotic stress. A pot experiment was conducted to evaluate the impact of seed priming with potassium nitrate (KNO₃) at various levels (0%, 0.50%, 1.00% and 1.50%) under salt stress (0, 75, 100 mM NaCl) on two maize verities (MNH360 and 30T60) for the growth, development and metabolic attributes results revealed that in maize variety MNH360, KNO₃ priming’s significantly enhanced growth parameters than in maize variety 30T60 under… More >

Abstract Maillard reaction is a non-enzymatic browning reaction and its products (MRPs) have been proven to possess antioxidant properties. This research aimed to produce a fish gelatin-based packaging incorporated with MRPs to retard lipid oxidation in chicken skin oil (CSO) during storage at ambient temperature (28°C–30°C). MRPs produced from fish gelatin and fructose (1:1, 90°C, pH 11) showed the highest antioxidant properties compared to those prepared under other conditions. Different glycerol/MRPs ratios (30:0, 25:5, 20:10, 15:15, 10:20, 5:25, 0:30) were incorporated into the film and resulting films were characterized. Glycerol/MRPs at 10:20 ratio was chosen to… More > Graphic Abstract

Abstract Melatonin and abscisic acid, as major plant hormones, play important roles in the physiological and biochemical activities of crops, but the interaction between the two under salt stress is not yet clear. This study investigated the endogenous levels of melatonin and abscisic acid in rice by using exogenous melatonin, abscisic acid, and their synthetic inhibitors, and examined their interactions under salt stress. The research results indicate that melatonin and abscisic acid can improve rice salt tolerance. Melatonin alleviated the salt sensitivity caused by abscisic acid deficiency, increased antioxidant enzyme activity and antioxidant content in rice More >

Abstract Dōng líng căo, the dried aboveground parts of Isodon rubescens (Hemls.) Hara., is commonly consumed as a medicinal decoction or tea beverage. Natural beverages can be an important source of human dietary selenium (Se). However, how I. rubescens plants respond to exogenous Se remains unknown. In this study, a pot cultivation experiment was employed to investigate the phenotypic and physiological responses of I. rubescens plants exposed to Se. Fifteen days after applying different concentrations of sodium selenate to the soil, the Se enrichment capacity, growth indices, antioxidant capacities, and the content of flavonoids and diterpenoids were measured in… More >
