Abstract

While an excess of metals such as zinc, cadmium or nickel (Ni) is toxic for most plants, about 500 plant species called hyperaccumulators are able to accumulate high amounts of these metals. These plants and the underlying mechanisms are receiving an increasing interest because of their potential use in sustainable biotechnologies such as biofortification, phytoremediation, and phytomining. Among hyperaccumulators, about 400 species scattered in 40 families accumulate Ni. Despite this wide diversity, our current knowledge of the mechanisms involved in Ni accumulation is still limited and mostly restricted to temperate herbaceous Brassicaceae. New Caledonia is an archipelago of the tropical southwest pacific with a third of its surface (5500 km(2)) covered by Ni-rich soils originating from ultramafic rocks. The rich New Caledonia flora contains 2145 species adapted to these soils, among which 65 are Ni hyperaccumulators, including lianas, shrubs or trees, mostly belonging to the orders Celastrales, Oxalidales, Malpighiales, and Gentianales. We present here our current knowledge on Ni hyperaccumulators from New Caledonia and the latest molecular studies developed to better understand the mechanisms of Ni accumulation in these plants.

Statistics

Figures

Figure 1 Phylogenetic distribution of nickel hyperaccumulators using APG III classification. The number of Ni hyperaccumulator in each order is presented as a bar (logarithmic scale). The red bar indicates that the observed number of hyperaccumulators significantly exceed the theoretical number (hyperaccumulating species randomly distributed using a binomial law with a Bonferroni correction for multiple tests). H, indicates the presence of hypernickelophore species accumulating more than 10,000 ppm nickel. *, indicates the presence of hyperaccumulators from New Caledonia.

Figure 2 Psychotria gabriellae and Psychotria semperflorens as a model system to study nickel hyperaccumulation. The Ni hyperaccumulator P. gabriellae (red tag) and the closely related non-accumulator P. semperflorens (yellow tag) are living in sympatry in rain forest on ultramafic soil in New Caledonia (A). Both species are 1–3 meters shrub with very similar pink flowers (top right insert: P. semperflorens inflorescence). In natural growth condition, P. gabriellae accumulates up to 4% Ni in leaves while P. semperflorens accumulates approximately 100 times less Ni. These differences can be semi-quantitatively visualized on XRF spectra (B).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
