    Cd and Hg Mediated Oxidative Stress, Antioxidative Metabolism and Molecular Changes in Soybean (Glycine max L.)

    Sheeba Naaz1,2, Nadeem Ahmad2, Asma A. Al-Huqail3, Mohammad Irfan4, Faheema Khan3, Mohammad Irfan Qureshi1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.6, pp. 1725-1742, 2023, DOI:10.32604/phyton.2023.026100

    Abstract Cadmium (Cd) and Mercury (Hg) is among the heavy metals most hazardous for plant and human health. Known to induce oxidative stress in plants and disbalance equilibrium in the antioxidant defence system, these metals alter plant growth and cause damage at the cellular and molecular levels. Soybean is an important oilseed crop that is raised in soils often contaminated by Cd and Hg. The comparative studies on the deleterious effect of Cd and Hg and the defence system of antioxidants were not studied earlier in soybean plant. In this study, soybean plants were exposed to Cd (100 µM CdCl2) and… More >

    Silicon and Nitric Oxide-Mediated Regulation of Growth Attributes, Metabolites and Antioxidant Defense System of Radish (Raphanus sativus L.) under Arsenic Stress

    Savita Bhardwaj1, Tunisha Verma1, Ali Raza2,*, Dhriti Kapoor1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.3, pp. 763-782, 2023, DOI:10.32604/phyton.2023.025672


    Arsenic (As) contaminated food chains have emerged as a serious public concern for humans and animals and are known to affect the cultivation of edible crops throughout the world. Therefore, the present study was designed to investigate the individual as well as the combined effects of exogenous silicon (Si) and sodium nitroprusside (SNP), a nitric oxide (NO) donor, on plant growth, metabolites, and antioxidant defense systems of radish (Raphanus sativus L.) plants under three different concentrations of As stress, i.e., 0.3, 0.5, and 0.7 mM in a pot experiment. The results showed that As stress reduced the growth parameters of… More >

    Advances in Cotton Tolerance to Heavy Metal Stress and Applications to Remediate Heavy Metal-Contaminated Farmland Soil

    Ling Li*, Xuyu Yan, Juan Li, Yashan Tian, Pan Ren

    Phyton-International Journal of Experimental Botany, Vol.90, No.1, pp. 35-50, 2021, DOI:10.32604/phyton.2021.012276

    Abstract Heavy metal-contaminated soil is one of the major environmental pollution problems of agricultural production and human health in the world. Remediation of heavy metals in soil is one of the most popular research subjects. Different remediation strategies have been reported to remove heavy metals from contaminated soil, among which phytoremediation is the most important one. Compared with other major crops, cotton shows the strongest and most widespread resistance to abiotic stresses, such as heavy metals. Although heavy metal stress adversely affects the growth and development of cotton, cotton possesses a set of sophisticated stress-resistance strategies. As the main product of… More >

    Assessment of Castor Plant (Ricinus communis L.) Tolerance to Heavy Metal Stress-A Review

    Akwasi Yeboah1, Jiannong Lu1, Ting Yang1, Yuzhen Shi1, Hanna Amoanimaa-Dede1, Kwadwo Gyapong Agyenim Boateng2, Xuegui Yin1,*

    Phyton-International Journal of Experimental Botany, Vol.89, No.3, pp. 453-472, 2020, DOI:10.32604/phyton.2020.09267

    Abstract Increased urbanization and industrialization have greatly contributed to the emission of higher amount of heavy metals such as cadmium, nickel, and lead into the environment. These metals are non-biodegradable and toxic, causing much effects on plants and by extension to animals and humans, which have become a major global concern. The inherent ability of plants to resist heavy metal toxicity seems to be the most sustainable and cost-effective strategy. Castor plant is widely studied due to its tolerance to the effects of heavy metal contaminated soils, owing to its large biomass content and high accumulating capacity. Castor plants to some… More >
