| Description | Soil and water contamination is a serious worldwide concern; therefore, effective remediation approaches are urgently required. Microbe-assisted phytoremediation is a promising, inexpensive, and eco-friendly rehabilitation approach that uses a broad range of plants and their associated microbes for remediating pollutants present in different environmental matrices. They can metabolize, detoxify, and/or biotransform many refractory pollutants either to obtain carbon and/or energy for their growth or as co-substrates, thus converting them to simpler products such as carbon dioxide $(CO_{2}$) or water $(H_{2}$O) (Turnau et al. 2005; Phillips et al. 2008; Weyens et al. 2013; Liu et al. 2015). The composition of the microbial community in the soil–root interface can significantly assist plant establishment on heavy metal–contaminated soils by mediating nutrient mineralization and uptake by plants (Wu et al. 2006a,b; Ma et al. 2009a,b). Microbes may reduce the toxicity of metals or increase their bioavailability and thus have some potential to improve phytoextraction efficiency. Different mechanisms have been proposed to explain the beneficial effect of root-associated bacteria, which include production of phytohormones, antioxidant enzymes, biosurfactants, metal-chelating compounds, siderophores, cell wall–degrading enzymes, 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase enzyme, solubilization of minerals, and induced systemic tolerance (Jing et al. 2007; Bonfante and Genre 2010; Liu et al. 2013; Ahemad and Kibret 2014; Cabral et al. 2015; Chandra and Kumar 2015b). The metal-chelating molecules synthesized by bacteria may also act as a key mechanism in heavy metal accumulation and phytoremediation technology. The effects of heavy metals on plant and microbe interactions are complex and may be affected by various factors, such as the chemical nature of metals and concentrations, that should be taken into consideration.
