TLDR
Addition of iron, as a ferric metal chelate (iron ethylenediaminedihydroxyphenylacetic acid), to the growth medium overcame the interference of zinc.Abstract:
Zinc interfered with translocation of iron from roots to above ground parts of Glycine max. (L.) Merrill var. Hawkeye. During periods in which zinc impeded iron translocation, it also suppressed the production of reductant by roots. Addition of iron, as a ferric metal chelate (iron ethylenediaminedihydroxyphenylacetic acid), to the growth medium overcame the interference of zinc. In the root epidermis, potassium ferricyanide formed a precipitate (Prussian blue) with ferrous iron derived from the previously supplied iron ethylenediaminedihydroxyphenylacetic acid. The reduction of ferric iron was suppressed by zinc.read more

Tansley Review No. 111: Possible roles of zinc in protecting plant cells from damage by reactive oxygen species.
TL;DR: Zinc plays critical roles in the defence system of cells against ROS, and thus represents an excellent protective agent against the oxidation of several vital cell components such as membrane lipids and proteins, chlorophyll, SH-containing enzymes and DNA.

Obligatory reduction of ferric chelates in iron uptake by soybeans.
TL;DR: Separation and absorption of Fe from Fe(3+)-chelates appear to require reduction of Fe( 3+)-chelate to Fe(2+-chelate at the root, with Fe( 2+) being the principal form of Fe absorbed by soybean.

Toxicity of heavy metals (Zn, Cu, Cd, Pb) to vascular plants
TL;DR: In this paper, the authors reviewed the literature on heavy metal toxicity to vascular plants and the role of mycorrhizal infection as well, focusing on forest plant species, especially trees, and effects at low metal concentrations.

TL;DR: Differential tolerance of plant genotypes exposed to zinc toxicity is a promising approach to enrich the authors' understanding of zinc tolerance in plants and may help in interdisciplinary studies to assess the ecological significance of metal stress.
