| Abstract: | Metal trace elements, by their non-biodegradable nature, are ecotoxic and could be involved in many pathologies. It is therefore important to fully understand their effects on living organisms, but also to implement sustainable solutions to limit their risks. In our work, the impact of cadmium chloride on the chickpea (Cicer arietinum) is to be assessed via the determination of certain biomarkers of stress at the root level (glutathione (GSH), malondialdehyde (MDA), lipid, ascorbate peroxidase (APX) and glutathione peroxidase (GPX) activities) in the presence or absence of fungal strains. The results obtained show a fluctuation of the various parameters studied according to the increase in xenobiotic doses, suggesting the installation of oxidative stress and the induction of the antioxidant system. However, all values recorded in treated plants appear to be lower in the presence of Fusarium oxysporum and Aspergillus niger, suggesting that these fungi block the passage of metals through the plant by accumulating them, thereby reducing the effect of cadmium on plant metabolism. |
