Ecophysiology of nickel hyperaccumulating plants from South Africa – from ultramafic soil and mycorrhiza to plants and insects

Ecophysiological model “ultramafic soil – mycorrhiza – hyperaccumulating plants – specialised insects and other organisms” is presented for South African nickel hyperaccumulating plants.

Critical Review

Biomolecular approaches to understanding metal tolerance and hyperaccumulation in plants

Trace metal elements are essential for plant growth but become toxic at high concentrations, while some non-essential elements, such as Cd and As, show toxicity even in traces.

Elemental distribution and chemical speciation of copper and cobalt in three metallophytes from the copper–cobalt belt in Northern Zambia

Metallophytes from the Zambian copper–cobalt belt have a complex Cu–Co coordination chemistry and diverse elemental distribution at the tissue-level. This study reveals different ecophysiological responses in hyper-tolerant plant species growing in metalliferous environments.

Distribution and chemical form of selenium in Neptunia amplexicaulis from Central Queensland, Australia

Elemental mapping of selenium in the hyperaccumulator Neptunia amplexicaulis determined whole plant and tissue level selenium distribution. The total concentrations and chemical forms of selenium are also reported for this species.

Visible cellular distribution of cadmium and zinc in the hyperaccumulator Arabidopsis halleri ssp. gemmifera determined by 2-D X-ray fluorescence imaging using high-energy synchrotron radiation

SR-μ-XRF imaging has revealed that the distribution of Zn in leaves was different from that of Cd at a cellular level.

X-ray fluorescence spectroscopy (XRF) applied to plant science: challenges towards in vivo analysis of plants

X-ray fluorescence spectroscopy presents a unique capability to probe the elemental content of plants in vivo, besides combination with other non-destructive tools to assess physiological processes.

Identification and physiological comparison of plant species that show positive or negative co-occurrence with selenium hyperaccumulators

Reynolds and coworkers investigated effects of selenium hyperaccumulator plants on local vegetation. Shown is elemental distribution in Alyssum simplex.

Endosperm prevents toxic amounts of Zn from accumulating in the seed embryo – an adaptation to metalliferous sites in metal-tolerant Biscutella laevigata

The pseudometallophyte Biscutella laevigata adapts to metalliferous soils by allocating excess metal(loid)s to the endosperm (E) of seeds to protect embryonic tissues and improve reproductive success.

Evaluating effects of iron on manganese toxicity in soybean and sunflower using synchrotron-based X-ray fluorescence microscopy and X-ray absorption spectroscopy

Increased Fe in solution decreased Mn accumulation on soybean unifoliate leaves and in trichomes of sunflower lower alternate leaves.
