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 …

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 …

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 …

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 …

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 …

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 …

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 …

The mutants irt1‐1 and irt1‐2 of Arabidopsis thaliana were identified among a collection of T‐
DNA‐tagged lines on the basis of a decrease in the effective quantum yield of photosystem …
