TLDR
It was suggested that P. vulgaris could be used in rhizofiltration--the use of plant roots to absorb pollutants from water contaminated with lead, because of the highest rate of Pb ions uptake from the medium and after 96 h of incubation lead content in the medium decreased by half.About:

Heavy metals toxicity in plants: An overview on the role of glutathione and phytochelatins in heavy metal stress tolerance of plants
TL;DR: In this article, the effect of heavy metals exposure to plants and role of GSH and PCs in heavy metal stress tolerance were reviewed and genetic manipulations of both GSH levels and PC levels were presented.
Journal ArticleDOI
Heavy Metal Stress and Some Mechanisms of Plant Defense Response
TL;DR: An important additive component of plant defense system is symbiotic association with arbuscular mycorrhizal (AM) fungi, which can effectively immobilize HMs and reduce their uptake by host plants via binding metal ions to hyphal cell wall and excreting several extracellular biomolecules.

Lead Uptake, Toxicity, and Detoxification in Plants
TL;DR: The purpose of this review is to describe how plants take lead up and to link such uptake to the ecotoxicity of lead in plants, and to address the mechanisms by which plants or plant systems detoxify lead.

Lead detoxification by coontail (Ceratophyllum demersum L.) involves induction of phytochelatins and antioxidant system in response to its accumulation.

TL;DR: Results suggest that plants responded positively to moderate Pb concentrations and accumulated high amount of metal, due to metal accumulation coupled with detoxification potential, the plant appears to have potential for its use as phytoremediator species in aquatic environments having moderate pollution of Pb.

TL;DR: Among different Pb-remediation approaches, certain advanced approaches such as microbial assisted phytoremediation which could possibly minimize the Pb load from the resources in a sustainable manner and would be a viable option to ensure a safe food production system are highlighted.

Tissue sulfhydryl groups
TL;DR: A water-soluble (at pH 8) aromatic disulfide [5,5′-dithiobis(2-nitrobenzoic acid] has been synthesized and shown to be useful for determination of sulfhydryl groups.
Terrestrial higher plants which hyperaccumulate metallic elements. a review of their distribution, ecology and phytochemistry
TL;DR: Phytochemical studies suggest that hyperaccumulation is closely linked to the mechanism of metal tolerance involved in the successful colonization of metalliferous and otherwise phytotoxic soils.

Response to cadmium in higher plants
TL;DR: It is proposed that, above all in response to acute cadmium stress, various mechanisms might operate both in an additive and in a potentiating way, and a holistic and integrated approach seems to be necessary in the study of the response of higher plants to Cadmium.

Phytoextraction: The Use of Plants To Remove Heavy Metals from Soils
TL;DR: The high metal accumulation by some cultivars of B. juncea suggests that these plants may be used to clean up toxic metal-contaminated sites in a process termed phytoextraction.
Journal ArticleDOI
Phytochelatins and their roles in heavy metal detoxification
TL;DR: Plants respond to heavy metal toxicity in a variety of different ways, including immobilization, exclusion, chelation and compartmentalization of the metal ions, and the expression of more general stress response mechanisms such as ethylene and stress proteins.
