“…In forest plants, differences in sensitivity to Cd among clones were reported in willow and poplar species by Dos Santos et al (2007) and Zacchini et al (2009) in similar experimental conditions. A reduction of the root/shoot ratio in metal-exposed plants compared with control, found in both eucalypt clones, is commonly reported (Zhang et al, 2010;Fernandez et al, 2012;Iori et al, 2013b) and ascribed to the main toxic effect exerted by metals on plant roots. In this work, both eucalypt clones showed a remarkable ability to concentrate Cd in the roots, particularly in clone Velino.…”

“…A value of BAC>1 shows that the plant is enriched with an element (the plant is an accumulator). BAC<1 shows that the plant excludes elements from the uptake (excluder) [52][53]. When BAC surpasses 10, those plants have the ability to hyperaccumulate elements [54].…”

Our study was carried out on three peat bogs that since the 1960s have been subjected to different degrees of anthropopression. The main objective of the research was assessment of heavy metal accumulation potential in peat bogs and in leaves of species growing on these peat bogs, namely Scots pine (Pinus sylvestris L.), birch (Betula pendula Roth), and wild rosemary (Ledum palustre L.). The concentrations of lead and cadmium in peat of Bagno Bruch (the Upper Silesian Industrial Region) exceeded the permissible levels for soils of protected natural areas. Heavy metal concentrations in plants growing in all analyzed sites show no toxic levels. Among the examined species, birch showed the highest ability to accumulate cadmium and zinc.

“…We know that the hypocotyl is associated with the formation of plant roots. Zhang et al (2010) reported an increase in root length and biomass of A. hybridus under Cd (60 mg/kg) stress. In our experiment, phytochrome C was upregulated, which suggests that Cd stress can promote the growth and development of A. hybridus roots.…”

“…Plant seeds were collected from the farm at Sichuan Agricultural University in Sichuan Province (30°0′N, 103°1′E). Soil culture of the seedlings was performed according to the method described by Zhang et al (2010). Each plastic pot was filled with 6.0 kg of ground soil with or without (as a control) 60 mg/kg Cd (Cd solution was prepared by dissolving analytical grade CdCl 2 · 2.5 H 2 O).…”

Amaranthus hybridus L. has great potential for use in phytoremediation of soils contaminated with cadmium (Cd). In this study, we found higher absorption of Cd by the roots of A. hybridus than by its other organs. To understand the mechanism of Cd accumulation in A. hybridus roots, a comparative proteomic approach was used to differentiate the two-dimensional electrophoretic profiles of root proteins in Cd-free and Cd-treated plants. Twenty-eight differentially expressed proteins were successfully identified using matrixassisted laser desorption/ionization tandem time-offlight mass spectrometry. Of these, 10 were specifically expressed under Cd stress, and another 11 were upregulated and 7 downregulated by >2.5-fold under Cd stress. We observed increased expression of proteins involved in energy metabolism, protein metabolism, stress and defense, and signal transduction. These changes likely enhanced Cd tolerance and enrichment in A. hybridus. The downregulated proteins were mainly involved in the synthesis of microRNAs, cell walls, and other structural components. These observations were further confirmed by quantitative fluorescence PCR. The resulting differences in protein expression patterns suggest that redirection of root cell metabolism might be an important survival mechanism for A. hybridus under Cd stress.
