The article discusses the importance of biodiversity in phytoremediation, a technique that uses plants to clean up metal-contaminated environments. It highlights the potential of various plant species, particularly those from the Brassicaceae family, for hyperaccumulating metals like cadmium, nickel, and zinc. The authors emphasize the role of glutathione and organic acids in metal tolerance and the use of chelates and acidifying agents to enhance metal removal. They also explore the application of hyperaccumulators in ornamental plants, edible vegetables, and natural biofilters, as well as the significance of serpentinophytes in unique metal accumulation. The article concludes by discussing future directions, including genetic strategies and transgenic approaches to improve phytoremediation technologies.The article discusses the importance of biodiversity in phytoremediation, a technique that uses plants to clean up metal-contaminated environments.
