Using the field pot-culture and sample-analysis method, 54 weed species belonging to 20 families and 31 weed species belonging to 17 families were systematically examined as to whether they can exclude the uptake of heavy metals. After a systematic identification, it was determined that Oenothera biennis and Commelina communis were Cd-excluders and Taraxacum mongolicum was a Zn-excluder. O. biennis is a potential Cd-excluder, but also a potential Cu-excluder. The research raises the possibility… Expand
Naturally selected dominant weeds as heavy metal accumulators and excluders assisted by rhizosphere bacteria in a mining area.
Managers need more practical and promising plants for use in heavy metal phytoremediation. Although previous studies have identified the potential of some weeds and microbial strains inExpand
Identification of cadmium-excluding welsh onion (Allium fistulosum L.) cultivars and their mechanisms of low cadmium accumulation
TLDR
Screening out cadmium (Cd) excluding cultivars of a crop in agricultural production is an effective way to prohibit Cd entering into food chain and low bioaccumulation factor of the roots was the main mechanism of Cd-excluding welsh onion cultivars. Expand
Heavy metal accumulation and phytostabilization potential of dominant plant species growing on manganese mine tailings
Screening plants that are hypertolerant to and excluders of certain heavy metals plays a fundamental role in a remediation strategy for metalliferous mine tailings. A field survey of terrestrialExpand
THE ASSESSMENT OF TOLERANCE TO HEAVY METALS (Cd,Pb and Zn) AND THEIR ACCUMULATION IN THREE WEED SPECIES
Phytoextraction is gaining great attention as an alternative technique for remediation of heavy metal contaminated soils. A greenhouse study was conducted to assess heavy metal (Cd, Pb, and Zn)Expand
Screening for Cd-Safe Cultivars of Chinese Cabbage and a Preliminary Study on the Mechanisms of Cd Accumulation
TLDR
The analyses of the transport coefficient and expression levels showed that the differences in Cd accumulation among the Chinese cabbage cultivars were related to the expression of genes involved in absorption and transport rather than a root-to-shoot translocation limitation. Expand
Tolerance and accumulation of heavy metals by wild plant species grown in contaminated soils in Apulia region, Southern Italy
Many sites inside a protected area in Apulia region (Italy) have been contaminated with heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) because an inadequate disposal of a variety of wastes with differentExpand
Potential hyperaccumulation of Pb, Zn, Cu and Cd in endurant plants distributed in an old smeltery, northeast China
The absorption and accumulation of Pb, Zn, Cu and Cd in some endurant weed plant species that survived in an old smeltery in Liaoning, China, were systematically investigated. PotentialExpand
POTENTIAL OF SILYBUM MARIANUM L. FOR PHYTOREMEDIATION OF SOILS CONTAMINATED WITH HEAVY METALS
Comparative research has been conducted to allow us to determine the accumulation of heavy metals, micro and macroelements in the vegetative and reproductive organs of milk thistle, the quality ofExpand
Silicon-mediated heavy-metal tolerance in durum wheat : evidences of combined effects at the plant and soil levels
Plant growth is seriously limited by heavy metal toxicity. Studies suggest that silicon (Si) can alleviate the metal stress in plants but its bioavailability in soil is not well defined. This studyExpand

TLDR
Little molecular understanding of plant activities critical to phytoremediation has been achieved, but recent progress in characterizing Fe, Cd and Zn uptake by Arabidopsis and yeast mutants indicates strategies for developing transgenic improved phytOREmediation cultivars for commercial use.

Phytoextraction of cadmium with Thlaspi caerulescens
TLDR
It is shown that the population of the hyperaccumulator Thlaspi caerulescens from Viviez, which has a high Cd-accumulating capability, is an efficient tool to remove Cd from contaminated soils and may be used as a tool to efficiently reduce the availability of Cd in soils. Expand

TLDR
Accumulation of copper by the plant as expressed by concentration factors (CF) show that it is acting mainly as a copper excluder, and a further possible mechanism of tolerance is exhibited by the excretion of copper through its decaying leaves. Expand
