Heavy metal contamination in soils poses significant environmental and health risks worldwide. Traditional methods of soil remediation often involve costly and invasive techniques. Phyto-remediation, the use of plants to remove, stabilize, or degrade contaminants, has emerged as a promising alternative. However, natural plant species often exhibit limited tolerance and uptake capacities for heavy metals. This research paper explores the development and potential of transgenic plants engineered for enhanced phyto-remediation capabilities. By introducing specific genes encoding metal transporters, chelators, or enzymes into plant genomes, researchers aim to enhance plants' abilities to absorb, detoxify, and accumulate heavy metals. This paper reviews recent advancements in transgenic plant research for phyto-remediation, including strategies for gene selection, transformation techniques, and the assessment of transgenic plant performance in contaminated soils. Furthermore, it discusses the potential environmental implications, safety concerns, and regulatory aspects associated with the deployment of transgenic phyto-remediation plants. Overall, this paper highlights the promising prospects of transgenic plants as a sustainable and effective solution for addressing heavy metal contamination in soils.
