The metal chelator nicotianamine promotes the bioavailability of Fe and reduces cellular Fe
toxicity. For breeding Fe-efficient crops, we need to explore the fundamental impact of …

Nicotianamine chelates and transports micronutrient metal ions in plants. It has been
speculated that nicotianamine is involved in seed loading with micronutrients. A tomato …

The cellular and intracellular localization of the non-proteogenic amino acid nicotianamine
(NA) in leaves and root elongation zones was immunochemically investigated in pea (Pisum …

Nicotianamine (NA) is a non-protein amino acid derivative synthesized from S-adenosyl l-
methionine able to bind several metal ions such as iron, copper, manganese, zinc, or nickel …

Nicotianamine (NA), a chelator of metals, is ubiquitously present in higher plants.
Nicotianamine aminotransferase (NAAT) catalyzes the amino group transfer of NA in the …

Recent work has demonstrated that minerals in plants are circulated between root and
shoot. This occurs during the whole life time and renders possible response to changing …

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 …

The essential micronutrients Fe and Zn often limit plant growth but are toxic in excess.
Arabidopsis thaliana ZINC-INDUCED FACILITATOR1 (ZIF1) is a vacuolar membrane major …

The uptake of iron in plants is a highly regulated process that is induced on iron starvation.
In tomato, the mutant chloronerva exhibits constitutive expression of iron uptake responses …

Nicotianamine (NA) is among the most studied plant metal chelators. A large body of
evidence supports its crucial role for Fe distribution in plants and as a precursor of …
