Uptake and distribution of nickel and other metals in the hyperaccumulator Berkheya coddii
Open accessAbstract
Summary Berkheya coddii is a fast‐growing, high biomass nickel (Ni) hyperaccumulator plant that has recently attracted attention for its possible use in the phytoextraction of Ni. The mechanisms of Ni accumulation, however, are not well understood in this plant. Plants were grown hydroponically in varying Ni concentrations to assess the uptake and distribution of Ni, and other metals, at the whole plant level. X‐ray microanalyses (EDXA) of frozen hydrated tissues were conducted to determine the distribution of Ni at the cellular level in the leaves. Most Ni was found in the shoots, especially in the leaves. Leaf Ni concentration increased with age, whereas older stem sections had lower Ni concentrations than new growth. EDXA analyses revealed that the cuticle of the upper epidermis had a significantly higher Ni concentration than the rest of the leaf. The Ni concentrations in the other leaf tissues were not significantly different. This pattern of distribution contrasts sharply with some other hyperaccumulator species that commonly show a preferential accumulation of Ni and other metals in the vacuoles of the epidermal cells.

Numerous hyperaccumulators such as Berkheya coddii, Echium amoenum, Stipa hohenackeriana, Lens orientalis, and Taeniatherum crinitum have been identified for Ni accumulation.
“Numerous hyperaccumulators, such as Berkheya coddii Roessler, Echium amoenum Fisch. & C.A. Mey, Stipa hohenackeriana, Lens orientalis, and Taeniatherum crinitum (Schreb.) Nevski have also been identified for Ni accumulation (Robinson et al., 2003; Moameri et al., 2017).”
From Plant hyperaccumulators: a state-of-the-art review on mechanism of heavy metal transport and sequestration (2025) · cites this paper as Robinson et al., 2003
The Discussion (page unavailable) identifies Berkheya coddii as a nickel hyperaccumulator and reports nickel concentrations above the hyperaccumulation threshold. The cited paper does not identify Echium amoenum, Stipa hohenackeriana, Lens orientalis, or Taeniatherum crinitum as nickel hyperaccumulators, so it supports only the Berkheya coddii example in the jointly cited list.

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.
