Role of plant growth regulators and a saprobic fungus in enhancement of metal phytoextraction potential and stress alleviation in pearl millet

► PGRs have the ability to enhance metal uptake in plants like pearl millet. ► Leaves of native trees like M. oleifera can be used to enhance phytoextraction. ► Autochthonous fungi like T. puedokoningii can be used to enhance phytoextraction. ► PGRs and saprobic fungi can enhance phytoextraction by synergistic interaction. ► PGRs and saprobic fungi can play a role in stress alleviation of the plant used.
