In the era of rapid and extensive urbanization as well as industrialization, the environment's safety and security have become a matter of prime concern. Reducing various types of pollutants with the aid of plants and their associated microbes is known as phytoremediation. Phytoremediation uses various mechanisms like hyperaccumulation, vacuolar sequestration, volatilization, biotransformation, and degradation to detoxify the detrimental effects of a wide range of organic and inorganic pollutants. Conventional methods of soil remediation are time-consuming, expensive and labor-intensive, while phytoremediation is a natural, cost-efficient, and environmentally safe method. Biotechnological advancements may revolutionize phytoremediation. The knowledge of the candidate genes across the living organisms along with the genetic engineering approaches pertaining to sequestering, modifying, and degrading the recalcitrant and xenobiotics compounds may exert an additive effect on phytoremediation processes. Various technologies for altering the expression of genes and their related protein products which participate in the metal uptake, transport, and sequestration of harmful pollutants have revolutionized the new possibilities in phytoremediation.
