Research Interests: impact of abiotic stresses on natural and agricultural ecosystems

图片1.png


Summary

Abiotic stresses, including drought, salinity, extreme temperatures, and heavy metal toxicity, threaten global agricultural productivity and ecosystem stability. This special issue aims to compile innovative research and comprehensive reviews that explore the physiological, biochemical, and molecular mechanisms plants employ to cope with such stresses. We invite contributions highlighting advancements in understanding stress signaling pathways, adaptive responses, and the roles of secondary metabolites and nanoparticles in enhancing plant resilience. Furthermore, contributions may focus on applying biotechnological approaches to improve stress tolerance and sustainable agricultural practices. Key topics of interest for this special issue include, but are not limited to:


1)Physiological and biochemical responses of plants to abiotic stresses;

2)Molecular genetics and epigenetic regulation of stress tolerance;

3)Role of plant growth regulators and nutrients in stress mitigation;

4)Innovative agricultural techniques for stress management;

5)Interaction of multiple abiotic stresses and their cumulative effects.


This special issue serves as a platform for interdisciplinary research and aims to facilitate knowledge exchange among researchers, practitioners, and policymakers. We encourage submissions that contribute to a deeper understanding of plant responses to abiotic stress and explore potential solutions for enhancing food security in changing environmental conditions.

    Effects of Microplastics on Growth Pattern of Pinus massoniana and Schima uperba

    Keke Zhang, Yong Cui, Changchang Shao, Liqing Yang, Yuxin Wang, Yao Fang, Hua Zhou, Jie Wang, Honglang Duan
    Phyton-International Journal of Experimental Botany, Vol.94, No.9, pp. 2855-2871, 2025, DOI:10.32604/phyton.2025.065683
    (This article belongs to the Special Issue: Plant Responses to Abiotic Stress Mechanisms)
    Abstract As ubiquitous environmental contaminants, microplastics (MPs) have garnered global concern due to their persistence, bioaccumulation potential, and multifaceted threats to ecosystem health. These particles threaten terrestrial ecosystems via soil contamination; however, research on their phytotoxicity remains predominantly focused on herbaceous plants. The responses of woody plants to MPs and their interspecific differences are severely unexplored. Here, two important ecological and economical tree species in southern China, Pinus massoniana (P. massoniana) and Schima superba (S. superba), were selected to explore the ecotoxicity effects of polyethylene (PE) and polypropylene (PP) MPs (the two most abundant species in the soil) on… More >

    Compound Fertilizer Application Improves the Growth of Herbaceous Peony (Paeonia lactiflora Pall.) under High Temperature in Summer

    Zhipeng Sheng, Zhaoyu Hou, Jun Tao, Daqiu Zhao
    Phyton-International Journal of Experimental Botany, Vol.94, No.6, pp. 1751-1767, 2025, DOI:10.32604/phyton.2025.065874
    (This article belongs to the Special Issue: Plant Responses to Abiotic Stress Mechanisms)
    Abstract Summer high temperatures have severely impaired the growth of herbaceous peony (Paeonia lactiflora Pall.) in East China. While compound fertilizer application enhances soil fertility and promotes plant growth, its efficacy in maintaining optimal plant performance under summer heat stress remains poorly understood. This study investigated the effects of compound fertilizer application on herbaceous peony growth during summer thermal stress. Results demonstrated that compound fertilizer supplementation significantly improved plant growth under elevated temperatures, manifesting enhanced phenotypic characteristics, elevated antioxidant enzyme activities, and increased nutrient accumulation. Compared to untreated controls, fertilized plants exhibited three key responses: (1) increased More >

    Nanoparticle Innovations for Mitigating Metal Toxicity in Plants

    Maryam, Mohamed M. El-Mogy, Muhammad Faheem Jan, Iram Naz, Ishtiaq Ahmad, Riaz Ahmad, Muhammad Tanveer Altaf
    Phyton-International Journal of Experimental Botany, Vol.94, No.3, pp. 623-640, 2025, DOI:10.32604/phyton.2025.063763
    (This article belongs to the Special Issue: Plant Responses to Abiotic Stress Mechanisms)
    Abstract Various environmental stressors, such as salinity, heat, drought, and metals, present significant obstacles to crop productivity. This study delves into the adverse effects of metals, specifically focusing on cadmium (Cd), nickel (Ni), mercury (Hg), chromium (Cr), arsenic (As), lead (Pb), and copper (Cu) on plants. It explores the sources of these metals, examining both natural occurrences and human-induced activities, and investigates the mechanisms through which plants absorb them. Metal pollution, in particular, negatively affects plant and microbiome well-being, producing reactive oxygen species (ROS) that harm essential macromolecules. Traditional stress-resistant plant varieties necessitate substantial development, leading… More >

    Phyton-International Journal of Experimental Botany, Vol.94, No.3, pp. 641-655, 2025, DOI:10.32604/phyton.2025.062871
    (This article belongs to the Special Issue: Plant Responses to Abiotic Stress Mechanisms)
    Abstract The biochemical response of Coffea arabica var. Borbon to chitosan and chitosan oligosaccharides (COS) was evaluated in one-year-old plants under greenhouse conditions. COS solutions were synthesized through chemical and physical hydrolysis using acetic acid, hydrogen peroxide, and microwave irradiation. The obtained COS had an average molecular weight (Mw) of 3549.90 ± 0.33 Daltons (Da), a deacetylation degree (DD) of 76.64 ± 1.12%, and a polymerization degree (PD) of 18.91 ± 0.0018. Solutions of chitosan and COS were applied to C. arabica var. Borbon at concentrations of 0.25, 0.5, and 1 wt%. The experimental design was conducted using… More >
