Summary

The ability of plants to adapt to environmental stressors is critical for their survival and productivity. As climate change intensifies, understanding the metabolic mechanisms that underpin plant responses to abiotic and biotic stresses is more important than ever. This special issue aims to explore the intricate biochemical pathways and metabolic networks that enable plants to sense, respond to, and recover from various stress factors, including drought, salinity, temperature extremes, and pathogen attacks.

 

We invite contributions that reveal novel insights into metabolic changes induced by stress, the role of secondary metabolites, and the interaction between primary and secondary metabolism in stress adaptation. Studies employing advanced techniques such as metabolomics, transcriptomics, and proteomics are particularly encouraged, as they provide comprehensive perspectives on plant stress responses.

 

This special issue seeks to foster collaboration among researchers in plant biology, biochemistry, and stress physiology, ultimately contributing to a deeper understanding of plant resilience and informing future agricultural practices.

    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
    (This article belongs to the Special Issue: Metabolic Mechanisms of Plant Responses to Stress)
    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 >

    Physiological and Molecular Mechanisms of Freezing in Plants

    Ali Salehi Sardoei, Bahman Fazeli-Nasab
    Phyton-International Journal of Experimental Botany, Vol.94, No.6, pp. 1601-1630, 2025, DOI:10.32604/phyton.2025.064729
    (This article belongs to the Special Issue: Metabolic Mechanisms of Plant Responses to Stress)
    Abstract The ability of plants to tolerate cold is a complex process. When temperatures drop or freeze, plant tissues can develop ice, which dehydrates the cells. However, plants can protect themselves by preventing ice formation. This intricate response to cold stress is regulated by hormones, photoperiod, light, and various factors, in addition to genetic influences. In autumn, plants undergo morphological, physiological, biochemical, and molecular changes to prepare for the low temperatures of winter. Understanding cellular stress responses is crucial for genetic manipulation aimed at enhancing cold resistance. Early autumn frosts or late spring chills can cause… More >

    Microbial Strategies for Enhancing Nickel Nanoparticle Detoxification in Plants to Mitigate Heavy Metal Stress

    Hua Zhang, Ganghua Li
    Phyton-International Journal of Experimental Botany, Vol.94, No.5, pp. 1367-1399, 2025, DOI:10.32604/phyton.2025.064632
    (This article belongs to the Special Issue: Metabolic Mechanisms of Plant Responses to Stress)
    Abstract Soil naturally contains various heavy metals, however, their concentrations have reached toxic levels due to excessive agrochemical use and industrial activities. Heavy metals are persistent and non-biodegradable, causing environmental disruption and posing significant health hazards. Microbial-mediated remediation is a promising strategy to prevent heavy metal leaching and mobilization, facilitating their extraction and detoxification. Nickel (Ni), being a prevalent heavy metal pollutant, requires specific attention in remediation efforts. Plants have evolved defense mechanisms to cope with environmental stresses, including heavy metal toxicity, but such stress significantly reduces crop productivity. Beneficial microorganisms play a crucial role in… More >

    Understanding the Molecular Mechanisms of Nitrogen Assimilation in C3 Plants under Abiotic Stress: A Mini Review

    Saif Ullah, Izhar Ali
    Phyton-International Journal of Experimental Botany, Vol.94, No.4, pp. 1029-1045, 2025, DOI:10.32604/phyton.2025.064608
    (This article belongs to the Special Issue: Metabolic Mechanisms of Plant Responses to Stress)
    Abstract Nitrogen (N) assimilation is crucial for the growth and development of C3 plants, as it converts inorganic N into organic forms, important for protein synthesis, nucleic acids and other vital biomolecules. However, abiotic stressors such as drought, salinity, extreme temperatures and others significantly impact N uptake and utilization, thereby hindering plant growth and development. Recent advances in molecular biology have illuminated the complex networks that govern N assimilation under these stressful conditions, emphasizing the role of transcription factors, regulatory genes, and stress-responsive pathways. This review provides an integrated perspective on the latest research in nitrogen metabolism… More >
