Iron is an essential nutrient for plants, but excess iron is toxic due to its catalytic role in the
formation of hydroxyl radicals. Thus, iron uptake is highly regulated and induced only under …

Arabidopsis halleri ssp. halleri (accession Langelsheim) is a naturally selected zinc (Zn)‐
and cadmium‐tolerant Zn hyperaccumulator. This plant differs strikingly from its close …

The micronutrients iron (Fe), zinc (Zn), and copper (Cu) are essential for plants and the
humans and animals that consume plants. Increasing the micronutrient density of staple …

Maintaining the appropriate balance of iron between deficiency and toxicity requires fine-
tuned control of systems for iron uptake and storage. Both among fungal species and within …

The Arabidopsis FRO2 gene encodes the low-iron-inducible ferric chelate reductase
responsible for reduction of iron at the root surface. Here, we report that FRO2 and IRT1, the …

Despite the abundance of iron in nature, it is the third most limiting nutrient for plants due to
its minimal solubility in most soils. While certain soil microbes produce chelating agents that …

Relatively little is known about how metals such as iron are effluxed from cells, a necessary
step for transport from the root to the shoot. Ferroportin (FPN) is the sole iron efflux …

The NADPH oxidase is an electron transport chain in “professional” phagocytic cells that
transfers electrons from NADPH in the cytoplasm, across the wall of the phagocytic vacuole …

In plants, the excess of several heavy metals mimics iron (Fe) deficiency-induced chlorosis,
indicating a disturbance in Fe homeostasis. To examine the level at which heavy metals …

Here, we describe two members of the Arabidopsis (Arabidopsis thaliana) Yellow Stripe-
Like (YSL) family, AtYSL1 and AtYSL3. The YSL1 and YSL3 proteins are members of the …
