Dicotyledonous plants growing under limited iron availability initiate a response resulting in
the solubilization, reduction, and uptake of soil iron. The protein factors responsible for these …

The IRON-REGULATED TRANSPORTER1 (IRT1) is the principal importer of soil iron in
Arabidopsis thaliana. It has a complex intracellular trafficking behavior, including continuous …

Iron is an essential micronutrient but is toxic if accumulated at high levels. Thus, iron uptake
and distribution in plants are controlled by precise regulatory mechanisms. IRON …

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 …

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 …

SUMMARY IRON‐REGULATED TRANSPORTER1 (IRT1) is the root high‐affinity ferrous
iron (Fe) uptake system and indispensable for the completion of the life cycle of Arabidopsis …

Plants take up iron from the soil using the IRON-REGULATED TRANSPORTER 1 (IRT1)
high-affinity iron transporter at the root surface. Sophisticated regulatory mechanisms allow …

Nickel (Ni) is an essential nutrient for plants, but excessive amounts can be toxic. Ni
competes with iron (Fe) in vivo, raising the possibility that Ni is competitively taken up via the …

The mechanisms of root iron uptake and the transcriptional networks that control root-level
regulation of iron uptake have been well studied, but the mechanisms by which shoots …

In plants, the controlled absorption of soil nutrients by root epidermal cells is critical for
growth and development. IRON-REGULATED TRANSPORTER 1 (IRT1) is the main root …
