During the combined plant-microbe remediation of heavy metal pollution in soil, PGPB can regulate the physiological processes of plants and reduce the stress from heavy metals on plants; simultaneously, the strains can activate insoluble heavy metals and phosphorus nutrients in the soil by producing iron carriers and organic acids. It involve in the production of reactive oxygen species which leads to subsequent cell death, eventually results in reduction in crop growth and yield.

The effect of heavy metal toxicity on the growth and development of plants differs according to the particular heavy Citric acid as a ligand is expected to enhance the availability of Ni in the soil so that Ni uptake by plants increases, while NPK fertilizer is expected to enhance crop biomass production. However, in higher amounts they may decrease plant growth. Stress factors particularly heavy metals can have additive, synergic or antagonist effects on plant growth.

This chapter summarizes the origin, role, and impact of heavy metals on plants, followed by plant defense mechanisms to counteract heavy metal stress, and finally, remediation techniques for removal of heavy metal contaminants. The metallicolous ecotype featured greater accumulation of photosynthetic pigments, enhanced activity of superoxide dismutase and increased content of specific phenol groups in comparison with the NM one. Therefore, sensitive plants growing in sites with heavy metals exposure show altered metabolism, growth reduction, and reduced biomass production and reduced yield. Using Martian regolith as plant support negates the need to bring growing structures from earth, but fresh regolith impairs plant growth due to the presence of toxic amounts of several heavy metals, The increasing heavy metal concentrations in agricultural lands due to various industrial activities adversely affect crop growth and metabolism consequently lowering yields with concomitant quality deteriorations. Microscopic analysis of M leaves showed a lack of dysfunctions in mesophyll cells exposed to TMs. The magnitude of soil contamination can be minimized through the use of viable technology by means of using suitable plant species; the approach is called phytoremediation.
