    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 - 29 May 2025

    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 > Graphic Abstract

    Insights into the Roles of Melatonin in Alleviating Heavy Metal Toxicity in Crop Plants

    Ling Li*,#, Xuyu Yan#

    Phyton-International Journal of Experimental Botany, Vol.90, No.6, pp. 1559-1572, 2021, DOI:10.32604/phyton.2021.016692 - 28 June 2021

    Abstract Alleviating heavy metal pollution in farmland soil, and heavy metal toxicity in plants is the focus of global agricultural environmental research. Melatonin is a kind of indoleamine compound that wide exists in organisms; it is currently known as an endogenous free radical scavenger with the strongest antioxidant effect. As a new plant growth regulator and signaling molecule, melatonin plays an important role in plant resistance to biotic or abiotic stress. Recent studies indicate that melatonin can effectively alleviate heavy metal toxicity in crop plants, which provides a new strategy to minimize heavy metal pollution in… More >
