“…HM-tolerant plants can grow in the presence of metals; however, they behave differently according to species and genotype [ 20 ]. Plants have been grouped into excluders, indicators, and accumulators according to the HM concentration they can store in their tissues, regarding the amount found in the soil ( Figure 1 ) [ 20 , 21 ].…”

“…Excluder plants can tolerate the presence of high HM concentrations in the soil because they restrict the entry and translocation of HM to aerial tissues, which allows them to maintain low HM concentrations in aerial tissues regardless of the concentration in the soil [ 21 , 22 , 23 ]. Excluder plants include grass family members such as Sudan grass, barley grass, and fescue [ 20 ].…”

“…The indicator species are sensitive to HMs and can accumulate proportional HM concentrations to those found in the soil [ 21 , 22 ]. This group includes grain and cereal crops such as corn, soybeans, wheat, and oats [ 20 ].…”

“…Accumulator plants actively absorb metals from the soil and accumulate them in their aerial biomass in non-toxic forms. These plants can contain higher concentrations of HMs in their tissues than the HM concentration found in the soil [ 20 , 22 ]. Some accumulator plants can grow in soils highly contaminated with HMs and accumulate high concentrations in their aerial tissues without showing signs of toxicity.…”

Heavy metal pollution is a severe concern worldwide, owing to its harmful effects on ecosystems. Phytoremediation has been applied to remove heavy metals from water, soils, and sediments by using plants and associated microorganisms to restore contaminated sites. The Typha genus is one of the most important genera used in phytoremediation strategies because of its rapid growth rate, high biomass production, and the accumulation of heavy metals in its roots. Plant growth-promoting rhizobacteria have attracted much attention because they exert biochemical activities that improve plant growth, tolerance, and the accumulation of heavy metals in plant tissues. Because of their beneficial effects on plants, some studies have identified bacterial communities associated with the roots of Typha species growing in the presence of heavy metals. This review describes in detail the phytoremediation process and highlights the application of Typha species. Then, it describes bacterial communities associated with roots of Typha growing in natural ecosystems and wetlands contaminated with heavy metals. Data indicated that bacteria from the phylum Proteobacteria are the primary colonizers of the rhizosphere and root-endosphere of Typha species growing in contaminated and non-contaminated environments. Proteobacteria include bacteria that can grow in different environments due to their ability to use various carbon sources. Some bacterial species exert biochemical activities that contribute to plant growth and tolerance to heavy metals and enhance phytoremediation.
