Proper metal transport and homeostasis are critical for the growth and development of
plants. In order to potentially fortify plants pre-harvest with essential metals in aid of human …

Compared to other organisms, plants have expanded families of transporters that are
involved in the uptake and efflux of metals. Fortunately, in many cases, the examination of …

Iron deficiency is a major human nutritional problem wherever plant-based diets are
common. Using synchrotron x-ray fluorescence microtomography to directly visualize iron in …

The micronutrient zinc has an essential role in physiological and metabolic processes in
plants as a cofactor or structural element in 300 catalytic and noncatalytic proteins, but it is …

Zinc ions are required to maintain the biological activity of numerous proteins. However,
when mislocalized or accumulated in excess, Zn2+ ions are toxic because of adventitious …

The Arabidopsis FRO2 gene encodes the iron deficiency-inducible ferric chelate reductase
responsible for reduction of iron at the root surface; subsequent transport of iron across the …

Iron acquisition in Arabidopsis depends mainly on AtIRT1, a Fe 2+ transporter in the plasma
membrane of root cells. However, substrate specificity of AtIRT1 is low, leading to an excess …

To clarify the molecular mechanism that regulates iron (Fe) acquisition in graminaceous
plants, a time-course analysis of gene expression during Fe deficiency stress was …

Nutritional micronutrient deficiencies and exposure to pollutant metals threaten human
health globally. Plant crops are at the beginning of a food chain that largely determines food …

Background Population and environmental pressure have imposed a great challenge on
agriculture in China to explore innovative and effective solutions to its pressing plant …
