Although iron deficiency poses severe nutritional problems to crop plants, to date iron
transporters have only been characterized from the model plant Arabidopsis thaliana. To …

Iron is an essential nutrient for virtually all organisms. The IRT1 (iron-regulated transporter)
gene of the plant Arabidopsis thaliana, encoding a probable Fe (II) transporter, was cloned …

Rice cDNA and genomic libraries were screened in order to clone an Fe (II) transporter
gene. A cDNA clone highly homologous to the Arabidopsis Fe (II) transporter gene IRT1 was …

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 …

Metal transporters regulated by iron can transport a variety of divalent metals, suggesting
that iron regulation is important for specificity of iron transport. In plants, the iron-regulated …

Only graminaceous monocots possess the Strategy II iron (Fe)‐uptake system in which Fe is
absorbed by roots as an Fe3+‐phytosiderophore. In spite of being a Strategy II plant …

Iron uptake from the soil is a tightly controlled process in plant roots, involving specialized
transporters. One such transporter, IRT1, was identified in Arabidopsis thaliana and shown …

Plants are the principal source of iron in most diets, yet iron availability often limits plant
growth. In response to iron deficiency, Arabidopsis roots induce the expression of the …

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 …

Fe uptake in dicotyledonous plants is mediated by a root plasma membrane-bound ferric
reductase that reduces extracellular Fe (III)-chelates, releasing Fe 2+ ions, which are then …
