    Olga S. Tsiftsoglou1,*, Vladimir Mihailovic2, Nikola Sreckovic2, Jelena S. Katanic Stankovic3, Kyriakos Michail Dimitriadis1, Michalis K. Stefanakis4, Diamanto Lazari1

    Phyton-International Journal of Experimental Botany, Vol.95, No.1, 2026, DOI:10.32604/phyton.2026.075566 - 30 January 2026

    Abstract Achillea species are known for their healing properties since ancient times. There is extensive literature on their pharmacological action due to their bioactive compounds. The present study aimed to investigate the antioxidant and antimicrobial effects of hydroalcoholic extracts from the inflorescences and leaves of the species Achillea crithmifolia Waldst. and Kit., A. grandifolia Friv. and A. millefolium L. The phytochemical profiles of all extracts were evaluated both by NMR spectroscopy and LC-MS analysis, and the results were consistent with the spectrophotometrically determined total phenolic (TP: 125.42–191.98 mg/g) and total flavonoid (TF: 47.34–180.02 mg/g) contents. All the extracts were tested More >

    Abstract Origanum elongatum (OE) is an aromatic, medicinal plant endemic to Morocco that is widely used in traditional medicine due to its biological properties. This study aimed to elucidate the chemical composition of the essential oil (EO) obtained from O. elongatum (OEEO) at three stages of its life cycle, including vegetative stage (OEEO-VS), flowering stage (OEEO-FS), and post-flowering (OEEO-PFS), as well as to evaluate its biological and antiradical characteristics. The chemical analysis of the essential oil was conducted using gas chromatography-mass spectrometry (GC-MS). The antibacterial activity was evaluated in vitro through distinct methodologies, namely, disc diffusion and microatmosphere assay;… More >

    Impacts of Fertilization and Soil Amendments on Rhizosphere Microbiota and Growth of Panax: A Meta-Analysis

    Hong Chen1,2, Runze Yang1,2, Jing Tian1,2, Boyuan Xu1,2, Qiang Chen3, Yuzong Chen1,2, Ming-Xiao Zhao1,2,*

    Phyton-International Journal of Experimental Botany, Vol.95, No.1, 2026, DOI:10.32604/phyton.2025.072276 - 30 January 2026

    Abstract Panax species are globally recognized for their high medicinal and economic value, yet large-scale cultivation is constrained by high production costs, progressive soil acidification, and persistent soil-borne diseases. Although various soil improvement strategies have been tested, a comprehensive synthesis of their comparative effectiveness has been lacking. Here, we conducted a meta-analysis of 1381 observations from 54 independent studies to evaluate the effects of conventional fertilizers, microbial fertilizers, organic amendments, and inorganic amendments on Panax cultivation. Our results demonstrate that microbial fertilizers, organic amendments, and inorganic amendments significantly increased soil pH, thereby ameliorating soil acidification. Among them,… More >

    Enhancing anticancer, antioxidant, and antibacterial activities of chalcogen-based SnSe nanoparticles synthesized through the co-precipitation method

    H. A. Rather1,*, J. B. A. Wahid2, M. A. Dar3, L. Guganathan4, U. A. Dar5, P. Arularasan6, S. E. I. Yagoub7, L. G. Amin7

    Chalcogenide Letters, Vol.22, No.5, pp. 461-468, 2025, DOI:10.15251/CL.2025.225.461

    Abstract SnSe powdered nanoparticles (NPs) are prepared using the co-precipitation method. The powdered NPs were studied using X-ray diffraction (XRD), UV-absorbance spectroscopy, and scanning electron microscopy (SEM) characterization techniques. The XRD result indicates that NPs are orthorhombic with a crystalline size of 4 nm for TS-1, 6 nm for TS-2, and 13 nm for TS-3, respectively. The SEM images show the surface morphology of the prepared NPs is not fully spherical, but semi-flower-like. The optical properties of the powdered NPs are found by UV-Vis absorbance spectroscopy, in which the highest absorbance was found between 200 nm More >

    Metabolic Adaptations of Cyanobacteria to Environmental Stress: Mechanisms and Biotechnological Potentials

    Riya Tripathi, Varsha K. Singh, Palak Rana, Sapana Jha, Ashish P. Singh, Payel Rana, Rajeshwar P. Sinha*

    Phyton-International Journal of Experimental Botany, Vol.94, No.11, pp. 3371-3399, 2025, DOI:10.32604/phyton.2025.070712 - 01 December 2025

    Abstract Cyanobacteria are photosynthetic prokaryotes. They exhibit remarkable metabolic adaptability, enabling them to withstand oxidative stress, high salinity, temperature extremes, and UV radiation (UVR). Their adaptive strategies involve complex regulatory networks that affect gene expression, enzyme activity, and metabolite fluxes to maintain cellular homeostasis. Key stress response systems include the production of antioxidants such as peroxidases (POD), catalase (CAT), and superoxide dismutase (SOD), which detoxify reactive oxygen species (ROS). To withstand environmental stresses, cyanobacteria maintain osmotic balance by accumulating compatible solutes, such as glycine betaine, sucrose, and trehalose. They also adapt to temperature and light fluctuations… More >

    Facile Preparation of Robust Peach Gum Polysaccharide with Remarkably Enhanced Antibacterial and Antioxidant Performance

    Mengting Huang, Meiting Lu, Li Yang, Jiwen Long, Li Zhou*

    Journal of Renewable Materials, Vol.13, No.10, pp. 2077-2090, 2025, DOI:10.32604/jrm.2025.02025-0122 - 22 October 2025

    Abstract Peach gum polysaccharide (PGP), a readily available natural polysaccharide, boasts substantial potential across diverse applications, yet its practical utility is severely limited by its vulnerability to bacterial growth and limited antioxidant activity. Herein, we introduced a simple and effective method to enhance the antibacterial and antioxidant properties of PGP by conjugating it with salicylic acid (SA). Cytotoxicity evaluation results confirmed that the resulting PGP-SA retains the excellent biocompatibility of PGP. Notably, PGP-SA demonstrates outstanding antibacterial activity against both Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria, outperforming non-modified PGP. Its antibacterial mechanism is hypothesized to stem from… More > Graphic Abstract

    Design of Nanostructured Surfaces and Hydrogel Coatings for Anti-Bacterial Adhesion

    Nanpu Cao1, Huan Luo1, Song Yue1, Yong Chen1, Mao Xu1, Pu Cao1, Tao Xin1, Hongying Luo1, Fa Zhang2,*

    Journal of Polymer Materials, Vol.42, No.3, pp. 661-675, 2025, DOI:10.32604/jpm.2025.067313 - 30 September 2025

    Abstract This review systematically summarizes recent advancements in the design of antibacterial hydrogels and the surface-related factors influencing microbial adhesion to polymeric materials. Hydrogels, characterized by their three-dimensional porous architecture and ultra-high water content, serve as ideal platforms for incorporating antibacterial agents (e.g., metal ions, natural polymers) through physical/chemical interactions, enabling sustained release and enhanced antibacterial efficacy. For traditional polymers, surface properties (e.g., roughness, charge, superhydrophobicity, free energy, nanoforce gradients) play critical roles in microbial adhesion. Modifying the surface properties of polymers through surface treatment can regulate antibacterial performance. In particular, by referencing the micro/nanostructures found More >

    Planting Years Drive Structural and Functional Shifts in the Rhizosphere Bacterial Microbiome of Zanthoxylum bungeanum

    De Zhang1,2, Yuan-Zu Ji1, Tong Zhao1, Jun-Ying Zhao1,*

    Phyton-International Journal of Experimental Botany, Vol.94, No.9, pp. 2815-2838, 2025, DOI:10.32604/phyton.2025.069196 - 30 September 2025

    Abstract This study investigated the effects of planting duration (1, 5, 10 and 15 years) on soil properties, bacterial community diversity, and function in the rhizosphere of Zanthoxylum bungeanum. We employed Illumina high-throughput sequencing and PICRUSt2 functional prediction to analyze the structure and functional potential of rhizosphere soil bacterial communities. The Mantel test and redundancy analysis were used to identify physicochemical factors influencing bacterial community structure and function. The results indicated significant differences in rhizosphere soil physicochemical properties across planting years: the content of organic matter, alkaline hydrolyzable nitrogen in the soil, as well as the activity… More >
