“…However, on some Zn-Pb mine waste sites in the south of France and in Slovenia, Noccaea species such as N. caerulescens and N. praecox have been found to typically contain >100 μg g À1 Cd, and >1000 μg g À1 locally, with very large variations existing among sites and populations, and considerable intra-site variability Escarré et al 2000;Lombi et al 2000;Reeves et al 2001;Schwartz et al 2006). Similar observations have been made for Arabidopsis halleri in Europe (Bert et al 2002) and for Sedum alfredii (Crassulaceae) and Viola baoshanensis (Violaceae) in PR China (Liu et al 2004;Deng et al 2008). As stressed by van der Ent et al …”

A large body of analytical data is available on the inorganic composition of many thousands of plant species, for which typical concentration ranges have been tabulated for major, minor, and trace elements. These elements include those that have been shown essential for plant growth, as well as others that lack this status, at least universally. Metalliferous soils, having abnormally high concentrations of some of the elements that are generally present only at minor (e.g. 200-2000 μg g À1 ) or trace (e.g. 0.1-200 μg g À1 ) levels, vary widely in their effects on plants and have attracted increasing attention during the last 50 years. The effects depend on the species, the relevant elements, and soil characteristics that influence the availability of metals to plants. Some of these soils are toxic to all or most higher plants. Others have hosted the development of specialized plant communities consisting of a restricted and locally characteristic range of metal-tolerant species. These plants often show a slightly elevated concentration of the elements with which the soil is enriched, but in places a species exhibits extreme accumulation of one or more of these elements, to a concentration level that may be hundreds or even thousands of times greater than that usually found in plants on the most common soils. These plants, now widely referred to as hyperaccumulators, are a remarkable resource for many types of fundamental scientific investigation (plant systematics, ecophysiology, biochemistry, genetics, and molecular biology) and for applications such as phytoremediation and agromining, and are discussed in detail below.

“…It was shown to hyperaccumulate Cd and to be more tolerant to Cd than most species ). Other Cd hyperaccumulators have been identified, notably N. caerulescens (Robinson et al 1998), Arabidopsis halleri (Bert et al 2002), Rorippa globosa (Sun et al 2007), S. nigrum (Wei et al 2006), Sedum alfredii (Yang et al 2004), Viola baoshanensis (Liu et al 2004), and S. plumbizincicola (Li et al 2014), but none of these plants are native to Australia (van der Ent et al 2013). In combination with its easy growing, and salt-and drought-tolerant traits, this native species, C. rossii, could be a promising candidate for phytoremediation of Cd-contaminated soils, especially in drought-prone areas and soils with high salinity .…”

Using hyperaccumulator plants is an important method to remove heavy metals from contaminated land. Carpobrotus rossii, a newly found Cd hyperaccumulator, has shown potential to remediate Cd-contaminated soils. This study examined the effect of nitrogen forms on Cd phytoextraction by C. rossii. The plants were grown for 78 days in an acid soil spiked with 20 mg Cd kg −1 and supplied with (NH 4 ) 2 SO 4 , Ca(NO 3 ) 2 , urea, and chicken manure as nitrogen (N) fertilizers. Nitrification inhibitor dicyandiamide (DCD) was applied to maintain the ammonium (NH 4 + ) form. Nitrogen fertilization increased shoot biomass but decreased root biomass with the highest shoot biomass occurring in the manure treatment. Compared to the no-N control, urea application did not affect shoot Cd concentration, but increased Cd content by 17 % due to shoot biomass increase. Chicken manure significantly decreased CaCl 2 -extractable Cd in soil, and the Cd concentration and total Cd uptake in the plant. Rhizosphere pH was the highest in the manure treatment and the lowest in the NH 4 + treatments. The manure and nitrate (NO 3 − ) treatments tended to have higher rhizosphere pH than their respective bulk soil pH, whereas the opposite was observed for urea and NH 4 + treatments. Furthermore, the concentrations of extractable Cd in soil and Cd in the plant correlated negatively with rhizosphere pH. The study concludes that urea significantly enhanced the Cd phytoaccumulation by C. rossii while chicken manure decreased Cd availability in soil and thus the phytoextraction efficiency.

“…Two of the most intensively studied species of hyperaccumulator plants, Arabidopsis halleri (L.) O'Kane & Al-Shehbaz (formerly Cardaminopsis halleri (L.) Hayek) and Noccaea caerulescens (J Presl and C Presl) FK Mey. (formerly Thlaspi caerulescens J Presl and C Presl), display a basal, constitutive level of zinc tolerance and hyperaccumulation in both metallicolous and non-metallicolous populations (Meerts and Van Isacker, 1997;Bert et al, 2000Bert et al, , 2002Escarré et al, 2000;Frérot et al, 2003;Pauwels et al, 2006;Meyer et al, 2010). However, across the geographic range of these species, there is a significant positive correlation between the degree of tolerance and substrate metal concentration, indicative of local adaptation to the natural habitat (Roosens et al, 2003;Pauwels et al, 2005).…”

Evolution of nickel hyperaccumulation and serpentine adaptation in the Alyssum serpyllifolium species complex

et al. 2016

Metal hyperaccumulation is an uncommon but highly distinctive adaptation found in certain plants that can grow on metalliferous soils. Here we review what is known about evolution of metal hyperaccumulation in plants and describe a population-genetic analysis of the Alyssum serpyllifolium (Brassicaceae) species complex that includes populations of nickelhyperaccumulating as well as non-accumulating plants growing on serpentine (S) and non-serpentine (NS) soils, respectively. To test whether the S and NS populations belong to the same or separate closely related species, we analysed genetic variation within and between four S and four NS populations from across the Iberian peninsula. Based on microsatellites, genetic variation was similar in S and NS populations (average H o = 0.48). The populations were significantly differentiated from each other (overall F ST = 0.23), and the degree of differentiation between S and NS populations was similar to that within these two groups. However, high S versus NS differentiation was observed in DNA polymorphism of two genes putatively involved in adaptation to serpentine environments, IREG1 and NRAMP4, whereas no such differentiation was found in a gene (ASIL1) not expected to play a specific role in ecological adaptation in A. serpyllifolium. These results indicate that S and NS populations belong to the same species and that nickel hyperaccumulation in A. serpyllifolium appears to represent a case of adaptation to growth on serpentine soils. Further functional and evolutionary genetic work in this system has the potential to significantly advance our understanding of the evolution of metal hyperaccumulation in plants.
