“…To assess the influence of metalliferous soils, we collected plants from different types of soils based on literature records (Reeves et al, 2001;Banásová et al, 2008) and verified the reported values by the determination of soil and leaf metal concentrations (Table II). Populations Mohelno (CZ2), Bergenbach (F1), and Puy de Wolf (F3) are located on natural ultramafic/serpentine soils characterized by an unusually high magnesium-calcium ratio and high levels of Ni, cobalt, and chromium and sometimes of Cd and Zn (population F3; Table II).…”

“…Our measurements for the two French populations were in accordance with those reported by Reeves et al (2001), confirming the hyperaccumulation of Ni in Bergenbach and of Ni, Cd, and Zn in Puy de Wolf. The population of Špania Dolina (SK1), an old copper (Cu) mining area with high soil Cu concentrations, had leaf Zn concentrations in the hyperaccumulator range (Table II; Banásová et al, 2008). (Table II; Reeves et al, 2001).…”

Genome Structure of the Heavy Metal Hyperaccumulator Noccaea caerulescens and Its Stability on Metalliferous and Nonmetalliferous Soils

Noccaea caerulescens (formerly known as Thlaspi caerulescens), an extremophile heavy metal hyperaccumulator model plant in the Brassicaceae family, is a morphologically and phenotypically diverse species exhibiting metal tolerance and leaf accumulation of zinc, cadmium, and nickel. Here, we provide a detailed genome structure of the approximately 267-Mb N. caerulescens genome, which has descended from seven chromosomes of the ancestral proto-Calepineae Karyotype (n = 7) through an unusually high number of pericentric inversions. Genome analysis in two other related species, Noccaea jankae and Raparia bulbosa, showed that all three species, and thus probably the entire Coluteocarpeae tribe, have descended from the proto-Calepineae Karyotype. All three analyzed species share the chromosome structure of six out of seven chromosomes and an unusually high metal accumulation in leaves, which remains moderate in N. jankae and R. bulbosa and is extreme in N. caerulescens. Among these species, N. caerulescens has the most derived karyotype, with species-specific inversions on chromosome NC6, which grouped onto its bottom arm functionally related genes of zinc and iron metal homeostasis comprising the major candidate genes NICOTIANAMINE SYNTHASE2 and ZINC-INDUCED FACILITATOR-LIKE1. Concurrently, copper and organellar metal homeostasis genes, which are functionally unrelated to the extreme traits characteristic of N. caerulescens, were grouped onto the top arm of NC6. Compared with Arabidopsis thaliana, more distal chromosomal positions in N. caerulescens were enriched among more highly expressed metal homeostasis genes but not among other groups of genes. Thus, chromosome rearrangements could have facilitated the evolution of enhanced metal homeostasis gene expression, a known hallmark of metal hyperaccumulation.

“…However, another species from the Noccaea genus, N. rotundifolia, is considered to be a Pb hyperaccumulator, with a maximum Pb level in shoots of 8200 mg kg -1 was reported by Reeves and Brooks (1983). However, the predominant Pb accumulation in the roots of both N. rotundifolia and N. caerulescens was shown in both soil and solution experiments (Huang and Cunningham 1996, El Kheir et al 2008, Banasova et al 2008. The potential estimation of the phytoextraction efficiency of the hyperaccumulating plants based on one-off nutrient solution experiments or soil pot experiments is questionnable.…”

Three Cd and Zn hyperaccumulating plant species Noccaea caerulescens Noccaea praecox and Arabidopsis halleri (Brassicacceae) were cultivated in seven subsequent vegetation seasons in both pot and field conditions in soil highly contaminated with Cd, Pb, and Zn. The results confirmed the hyperaccumulation ability of both plant species, although A. halleri showed lower Cd uptake compared to N. caerulescens. Conversely, Pb phytoextraction was negligible for both species in this case. Because of the high variability in plant yield and element contents in the aboveground biomass of plants, great variation in Cd and Zn accumulation was observed during the experiment. The extraction ability in field conditions varied in the case of Cd from 0.2 to 2.9 kg ha(-1) (N. caerulescens) and up to 0.15 kg ha(-1) (A. halleri), and in the case of Zn from 0.2 to 6.4 kg ha(-1) (N. caerulescens) and up to 13.8 kg.ha(-1) (A. halleri). Taking into account the 20 cm root zone of the soil, the plants were able to extract up to 4.1% Cd and 0.2% Zn in one season. However, cropping measures should be optimized to improve and stabilize the long-term phytoextraction potential of these plants.

“…Banásová et al (2008) found mean Zn concentrations of 13650 mg/kg and of 10729 mg/kg in MET and NMET populations, respectively, in central Slovakia. However, the SE populations as well as other NM populations from the Larzac plateau had concentrations of up to 2510 mg/kg Zn (Noret et al 2005; Lefèbvre and Escarré, unpublished results) for the same soil Zn levels as in Luxembourg.…”

“…In the current study, the Cd mass difference is linked to differences in biomass because the Cd concentrations were very similar between a salt mixture (100Zn250Cd) and the monometallic salt (250CdSO 4 ). Basic et al 2006;Banásová et al 2008).…”

Aims Evaluate the genetic and environmental variability of metal concentration and metal mass of Noccaea caerulescens, from metalliferous (MET), non metalliferous (NMET) and serpentine (SERP) soils. Methods 18 populations were cultivated in 18 different growth conditions, such as a soil mine tailing, soils amended with zinc (Zn), cadmium (Cd) and nickel (Ni) salts (in mixtures or in monometallic salts) and a hydroponic solution with two Zn concentrations. Results MET populations had Zn concentrations lower than NMET and SERP in the different soils but higher Cd mass (the product of aerial biomass and foliar metal concentration). SERP had the highest Ni concentration and Ni mass values. The addition of Cd or Ni to a Zn-contaminated soil significantly decreases Zn concentration. In hydroponics, MET and NMET had equivalent Zn concentrations but these were three times higher than those obtained in soil experiments. Zn mass of NMET was significantly lower than MET with the latter having Zn mass values largely above those obtained in mine soil. Conclusions Results showed a large heterogeneity of responses among populations depending on the substrate used, and it was not possible to correctly assign a single population to its accurate origin with only one experiment. Finally, data on metal concentration obtained in culture soils are closer to those in field soils than those from hydroponics so that they could give a more accurate information on the accumulating capacity of Noccaea caerulescens and its use in phytoextraction of metals in field conditions.
