Abstract The fruits of Prunus cerasifera Ehrh. have been traditionally utilized as both medicinal and edible resource, however, their specific phytochemical profile and anti-inflammatory mechanisms remain to be fully elucidated. This study aimed to isolate and identify the chemical constituents from the fruits and evaluate their anti-inflammatory activities. The separation was performed using a combination of chromatographic techniques. The structures of the obtained compounds were elucidated using a combination of 1H and 13C nuclear magnetic resonance (NMR) and electrospray ionization mass spectrometry (ESI-MS). The anti-inflammatory activity of the compounds was initially investigated based on their capacity to inhibit… More >

Abstract Staphylococcal meningitis, a severe infection of the meninges, highlights the urgent need for new strategies to combat Staphylococcus aureus (S. aureus) infections. In this study, ethanolic leaf extracts of Coleus forskohlii were evaluated for their antibacterial potential against clinical S. aureus isolates associated with meningitis. Gas chromatography-mass spectrometry (GC-MS) analysis identified 15 phytochemical compounds, two of which—urs-12-en-28-ol (CID 22213452) and petroselaidic acid (CID 5282754) showed promising binding affinities (−7.5 and −5.9 kcal/mol, respectively) against S. aureus protein (30S ribosomal subunit) in molecular docking studies. In vitro assays confirmed the antibacterial activity of the crude extract, with a minimum inhibitory concentration (MIC) More >

Abstract Drought represents a major environmental challenge, limiting water availability to plants and disrupting their physiological functions and growth, particularly in dryland regions. Traditional strategies, including water conservation practices, plant breeding, and advanced tools such as genetic engineering, have been employed to enhance drought tolerance. However, these methods are often time-consuming and expensive. Plant growth-promoting bacteria (PGPR) present a promising alternative by forming symbiotic relationships with plant roots and boosting drought resilience. PGPR enhances plant tolerance to drought-induced water stress through complex biochemical and physiological mechanisms, including phytohormone modulation, exopolysaccharides production, nutrient uptake, and gene regulation.… More >

Abstract Pigment biofortification in rice, particularly through enhanced anthocyanin accumulation, is increasingly recognized in Asia for its potential to improve nutritional quality and antioxidant capacity while addressing regional health challenges. However, the regulatory network underlying anthocyanin biosynthesis in rice remains incompletely characterized, especially regarding MYB transcription factors that may control pigment accumulation in diverse germplasm. In this study, a genome-wide analysis of MYB transcription factors in Oryza sativa subsp. japonica identified 109 OsMYB genes. Phylogenetic comparison with known anthocyanin regulators from Arabidopsis thaliana and Oryza rufipogon revealed conserved clades containing potential pigment-related regulators. Integrative analyses including gene structure, conserved motif identification,… More >

Abstract Citrus fruits are highly susceptible to post-harvest diseases such as green rot (Penicillium digitatum), blue rot (P. italicum), and sour rot (Geotrichum citri-aurantii), causing significant economic losses. Due to the risks associated with synthetic fungicides and the emergence of resistant strains, natural alternatives are needed. This study evaluated the antifungal activity of aqueous extracts of Corrigiola telephiifolia and Marrubium vulgare. In vitro tests were conducted using PDA medium with extract concentrations of 12.5–100 mg/mL and in vivo assays were performed on artificially wounded oranges with the same extract concentrations. In vitro tests showed strong inhibition of mycelial growth and spore germination, with C. telephiifolia More >

Abstract Climate change is increasing the frequency and intensity of overlapping abiotic stresses, making cross-tolerance a critical component of plant resilience. While single stress responses have been extensively characterized, plants in natural and agricultural environments frequently encounter simultaneous or sequential stresses such as drought–heat, light–drought, and drought–salinity, which trigger nonadditive and often unpredictable physiological outcomes that vary with stress intensity, timing, and species. This review synthesizes current understanding of the mechanisms underlying cross-tolerance, emphasizing how contradictory signals, stress timing, and physiological integration shape plant responses under combined stress. We highlight how stomatal regulation, leaf energy balance,… More >

Abstract Soil salinization is an increasingly severe global issue, posing a significant threat to crop growth and food security. Although sorghum exhibits moderate tolerance to saline-alkali stress, it remains highly sensitive to such conditions during the seedling stage. This study investigates the mechanisms by which zinc oxide nanoparticles (ZnO NPs) alleviate saline-alkali stress in sorghum seedlings and determines their optimal application concentration, thereby providing a scientific basis for agricultural production in saline-alkali soils. Hydroponic experiments were conducted to simulate varying degrees of saline-alkali stress. Sorghum seedlings were treated with different concentrations of ZnO NPs (0, 50,… More >

Abstract Pepper (Capsicum annuum L.) is highly susceptible to chilling stress, which severely constrains its growth and productivity. Although the eco-friendly biostimulant γ-polyglutamic acid (γ-PGA) has shown promise in enhancing plant tolerance to abiotic stresses, its specific role and underlying mechanisms in alleviating chilling injury in pepper remain poorly understood. This study systematically investigated the physiological and molecular mechanisms by which foliar application of 100 mg·L−1 γ-PGA enhances chilling tolerance in pepper seedlings. Our results demonstrated that γ-PGA pretreatment significantly mitigated chilling-induced growth inhibition and promoted root development, evidenced by a 110.8% increase in the number of root… More >

Abstract Artificial polyploidy induction is widely used in ornamental breeding but can yield aneuploidy derivatives that vary in developmental stability and breeding utility. In Hibiscus syriacus ‘Blue Bird’, in vivo colchicine and oryzalin treatments generated regenerated shoots in which genome-size shifts were detected by flow cytometry; among the candidate lines, a subset reached flowering maturity and was characterized in detail. These flowering aneuploids displayed diverse floral alterations, including reduced corolla size, altered pigmentation, and partial conversion of stamens into petaloid organs. Flow cytometry and somatic chromosome counts indicated aneuploid status (150–182 chromosomes). Pollen morphology was highly variable, with… More >

Abstract Acer truncatum is a significant woody oil-bearing tree species known for its ability to synthesize various unsaturated fatty acids. This study systematically analyzes the lipid metabolic pathways and the associated transcript abundance changes involved in the biosynthesis and accumulation of seed oil in A. truncatum. By integrating lipidomics and transcriptomics analyses across different developmental stages of A. truncatum seeds, we thoroughly investigate the dynamic characteristics of oil metabolism. The results show that triacylglycerols (TAGs) become the dominating lipid class throughout seed development and that their amount increases greatly as the seeds mature, whereas diacylglycerols (DAGs) show a significantly… More >
