Heavy metal contaminants like mercury is a serious problem to human, animals, and some plants’ health. Phytoremediation an alternative technique, which can remediate the from soil using hyperaccumulator plant. The goal of this research was study anatomical changes plant main organs (roots, stems, leaves) Ipomoea reptans are assumed as that grows in contaminant. concentration growth medium 0, 61...

Abstract Purpose The use of plant extracts obtained from plants that are highly tolerant to heavy metal toxicity has been beneficial in improving the growth grown under conditions. A lab experiment was performed elucidate alleviating role foliar applied cadmium (Cd)-hyperaccumulator Solanum nigrum ( S. ) extract on Datura innoxia D. Cd stress (0, 50, and 100 mg kg -1 soil). Methods Growth param...

Metallothioneins are cysteine-rich metal-binding proteins. In the present study, SaMT2, a type 2 metallothionein gene, was isolated from Cd/Zn co-hyperaccumulator Sedum alfredii Hance. SaMT2 encodes a putative peptide of 79 amino acid residues including two cysteine-rich domains. The transcript level of SaMT2 was higher in shoots than in roots of S. alfredii, and was significantly induced by Cd...

Cadmium (Cd) is a widespread, naturally occurring element present in soil, rock, water, plants and animals. Cd is a non-essential element for plants and is toxic at higher concentrations. Transcript profiles of roots of Arabidopsis thaliana (Arabidopsis) and Thlaspi caerulescens plants exposed to Cd and zinc (Zn) are examined, with the main aim to determine the differences in gene expression be...

The use of high energy x-ray fluorescence as a trace metal probe offers scientists an innovative tool for research. One application is the study of heavy metal accumulation in plant systems. The test species Thlaspi caerulescens has the ability to accumulate massive amounts of zinc, cadmium, and lead from contaminated soils as a form of bioremediation. In order to understand the efficiency of t...

Phytoremediation is a potential cleanup technology for the removal of heavy metals from contaminated soils. Bidens maximowicziana is a new Pb hyperaccumulator, which not only has remarkable tolerance to Pb but also extraordinary accumulation capacity for Pb. The maximum Pb concentration was 1509.3 mg/kg in roots and 2164.7 mg/kg in overground tissues. The Pb distribution order in the B. maximow...

Various pink-pigmented facultative methylotrophic (PPFM) bacteria (strains iEII3, iEIV1, iEI6, iEII1, iEIII3 iEIII4, iEIII5, iRII1, iRII2, iRIII1, iRIV1 and iRIV2) were obtained from the rhizosphere and endosphere of hyperaccumulating plant Thlaspi goesingense grown in Redschlag, Austria [R.
