“…Ma et al [51] confirmed these results and stated that cells accumulating Si significantly reduce the net Cd 2+ influx compared to cells not treated with Si. Nanotechnology offers a further approach to metal remediation through the design and use of micron-or nano-size metal-binding polymer particles with very high specific surface area [52] and high reactivity [53]. In this context, Cui et al [54] studied the impact of silica nanoparticles (SiNPs) on the attenuation of Cd toxicity in rice using a cell suspension culture and found that the presence of SiNPs allowed cells to remain almost intact even with high concentrations of Cd.…”

Heavy metals are among the most common and dangerous contaminants; their action on plants, as well as the possibility for plants to effectively absorb and translocate them, have been studied for several years, mainly for exploitation in phytoremediation, an environmentally friendly and potentially effective technology proposed and studied for the recovery of contaminated soils and waters. In this work, the analysis has focused on the studies developed using in vitro techniques on the possibilities of mitigating, in plants, the stress due to the presence of heavy metals and/or improving their absorption. These objectives can be pursued with the use of different substances and organisms, which have been examined in detail. The following are therefore presented in this review: an analysis of the role of metals and metalloids; the use of several plant growth regulators, with their mechanisms of action in different physiological phases of the plant; the activity of bacteria and fungi; and the role of other effective compounds, such as ascorbic acid and glutathione.
