Potential of Rhizospheric Fungi to Reduce Copper and Lead Toxicity in Triticum Aestivum L.
Plants are exposed to various heavy metals and other environmental stresses during anthropogenic evolution. The most common heavy metal contaminants are lead (Pb) and copper (Cu), which can be found in both natural and industrial settings. Microorganisms play a crucial role in the biotransformation of heavy metal-contaminated environments. In this study, four rhizospheric fungus strains were extracted from Parthenium hysterophorus L. and tested for their tolerance against lead and copper. These strains were selected for their ability to promote plant growth under heavy metal stress. When inoculated to Triticum aestivum L. under heavy metal stress, the fungal isolates NMG showed promising results in the form of increased secondary metabolites, hormones and enzymes.
Different concentrations of specific heavy metals (Pb25, Pb75, Cu100, Cu200, Pb25+Cu100, and Pb75+Cu200g/mL) were applied to wheat plants. The plants exposed to metal stress without microbial inoculation displayed a reduction in growth. However, when rhizospheric fungal inoculation restored plant growth and development, showed the symbiotic relationship between the fungus and the host plant roots under heavy metal stress conditions.
The isolates have the ability to transform HMs, making them unavailable for plant uptake and accumulation, which prevents harm to plants. Apart from their bioremediation properties, some isolates can create secondary metabolites like IAA, GA, MDA, ABA, H2O2, Electrolytic leakage, SA, lipid, DPPH, flavonoids, phenols, and proteins, which can stimulate plant growth and make them suitable for use as bio-fertilizers and bio-remediating agents in areas with high levels of heavy metal contamination.
