“…Therefore, suggesting S. portulacastrum as an efficient Pb 2+ extractor. Studies by Zaier et al (2010b) revealed presence of phytochelatin 3 (PC3) as the bioligand responsible for metal binding and detoxification of lead thus suggesting the application of Sesuvium and Brassica for phytoremediation of lead.…”

International audienceSesuvium portulacastrum L. is a pioneer plant species, used for sand-dune fixation, desalination and phytoremediation along coastal regions. The plant tolerates abiotic constraints such as salinity, drought and toxic metals. S. portulacastrum is also used as a vegetable, fodder for domestic animals and as an ornamental plant. S. portulacastrum grows luxuriantly at 100–400 mM NaCl concentrations. It further grows at severe salinity of 1000 mM NaCl without any toxic symptoms on the leaves. The plant also produces 20-hydroxyecdysone, an insect molting hormone for use in sericulture industry. This review analyses research undertaken during last two to three decades in physiology, biochemistry, molecular biology and biotechnology, to unravel the plasticity of the plant tolerance mechanism. Physiological and biochemical studies evidence the tolerance potential of the plant to abiotic stresses and reveal molecular mechanisms of stress tolerance. Biotechnological studies show the efficacy of the plant to produce pharmaceuticals. Large-scale multiplication of S. portulacastrum in the arid and semiarid regions should reduce the load of saline salts and heavy metals

“…Numerous studies found similar results that HMs toxicity significantly decreases the water content in the crops. For instance, Pb toxicity was found to decrease amount of water in Brassica juncea (Zaier et al 2010). Inhibition of plant growth, particularly the root length, was reported by the excessive accumulation of Zn (Wang et al 2009).…”

In this work, a pot experiment was conducted to evaluate the effect of organic amendments in alleviation of toxicity of untreated domestic wastewater to okra (Abelmoschus esculentus) and purslane (Portulaca oleracea). Three organic amendments including farm yard manure (FYM), poultry manure (PM) and bagasse ash (BGA) at the rate of 1% and 3% were applied to the soil to evaluate their positive impact on vegetable plants. Results showed that untreated wastewater impeded the growth of both vegetables and increased uptake of heavy metals (HMs) (i.e. Cu, Ni, Pb and Zn) by plants whereas organic amendments significantly improved the growth of plants and decreased the uptake of HMs. Shoot and root lengths and dry weights of plants were boosted by the FYM and PM, while chlorophyll a and b and carotenoids were enhanced by PM and BGA amendments. Interestingly, reduced HMs uptake was found where 3% of BGA or FYM were applied. Overall the results of this study showed that all three organic amendments were useful for improving growth of vegetables and alleviating the phytotoxicity of untreated wastewater and uptake of HMs by plants. Our findings suggest that these organic materials could be useful for improving agricultural productivity in untreated wastewater irrigated areas.

“…An example of an indirect toxic effect is the replacement of essential nutrients at the cation exchange sites of plants (Taiz and Zeiger 2002). For example, Zaier et al (2010) reported that the water content of Brasssica juncea plants remarkably decreases under Pb toxicity, although this species is considered tolerant. Servilia et al (2005) demonstrated that plants exposed to heavy metal exhibit stunted growth, deformation, reduced physicochemical activities, and overall alteration of cellular metabolism.…”

Biotransformation and removal of heavy metals: a review of phytoremediation and microbial remediation assessment on contaminated soil

et al. 2018

Environmental deterioration is caused by a variety of pollutants; however, heavy metals are often a major issue. Development and globalization has now also resulted in such pollution occurring in developing societies, including Africa and Asia. This review explores the geographical outlook of soil pollution with heavy metals. Various approaches used to remedy metal-polluted soils include physical, chemical, and biological systems, but many of these methods are not economically viable, and they do not ensure restoration without residual effects. This review evaluates the diverse use of plants and microbes in biotransformation and removal of heavy metals from contaminated soil. Mechanisms on how natural processes utilizing plants (phytoremediation) and microorganisms (bioremediation) remove or reduce heavy metals from soil at various levels are presented. This review concludes that remediation technologies are necessary for the recovery of metal-contaminated environments and the prevention of continuous environmentally toxic impacts on living organisms.
