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 …

Iron, an essential nutrient, is not readily available to plants because of its low solubility. In
addition, iron is toxic in excess, catalyzing the formation of hydroxyl radicals that can …

Iron is an essential nutrient for all organisms but toxic when present in excess.
Consequently, plants carefully regulate their iron uptake, dependent on the FRO2 ferric …

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 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 require metals for essential functions ranging from respiration to photosynthesis.
These metals also contribute to the nutritional value of plants for both humans and livestock …

IRT1 and IRT2 are members of the Arabidopsis ZIP metal transporter family that are
specifically induced by iron deprivation in roots and act as heterologous suppressors of …

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 …

The molecular basis for the transport of manganese across membranes in plant cells is
poorly understood. We have found that IRT1, an Arabidopsis thaliana metal ion transporter …

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 …
