Abstract: Phytoremediation which involves the use of plants and rhizospheric organisms for the removal of pollutants is an emerging technology for the clean up of contaminated sites. The removal of textile dyes mediated by plants has been one of the most neglected areas of phytoremediation research. Dyes, which are primary constituents of the wastes from textile industry effluents, constitute a group of recalcitrant compounds, many of which are known to have toxic and carcinogenic effects. Hence, the review focuses on the studies of the mechanisms adopted by plants in the removal of textile dyes and the future scope for research in this area which will help in broadening the horizons of phytoremediation technologies. Plant species many a times referred to as ‗green livers‘, are known to possess a wide range of detoxifying and biotransforming enzymes some of which may also be secreted extracellularly in the rhizosphere and can bring about the transformation of organic pollutants such as textile dyes.
