Hyperaccumulation of toxic heavy metals(THMs)by plants are extensively examined at the global level and considered a bioremediation strategy.The ability of hyperaccumulator plants(HPs)heavily depends on phytoextraction,rhizofiltration,phytodegradation and rhizoremediation.The efficacy of HPs is significantly enhanced by their association with rhizospheric microbes.HPs utilizes the unique characteristics of root-associated microbes including secondary metabolites,siderophores,exopolysaccharides,phytochelatins and other substances.Despite this potential,field scale bioremediation strategies are still not effective in removing THMs from contaminated sites.The plant’s root exudates and microbe-based secondary metabolites have the capacity to remove THMs through specific gene expression.The advent of Clustered-Regularly-Interspaced-Short-Palindromic-Repeats(CRISPR)technology enables the targeted editing of genes in both plants and root-associated microbes.This allows researchers to investigate and optimize hyperaccumulator mechanisms,manipulate the production of key biochemical compound and induce HP mechanisms.The genetic advances in manipulating microbes,regulation of root exudates,factors and soil additive agents integrates in maintaining rhizospheric engineering to increase THM removal.This synergistic approach helps to restore soil health,food and nutritional quality to effectively reclaim THM sites.The present review comprehensively addressed the outcomes of extensive research on bioremediation and highlights the advancement in THM removal through advance genetic editing and nanobiotechnology.This article introduces the“Bioremediation 1.0-3.0″paradigm,which combines traditional phytoremediation with new methods including omics,CRISPR and nanobiotechnology.Key opportunities include deploying gene-edited plants,microbe-nanomaterial complexes and integrated rhizospheric engineering for sustainable clean-up,soil restoration and food security.These initiatives will provide adaptable,sustainable and successful solutions for reducing hazardous heavy metals,improving soil health,safeguarding food systems and protecting ecosystems. 展开更多
