Nicotianamine, a plant-derived chelator of metals, is produced by the trimerization of S-
adenosylmethionine catalyzed by nicotianamine synthase. We established transgenic …

Nicotianamine is a methionine derivative involved in iron homeostasis, able to bind various
other metals in vitro. To investigate its role in vivo, we expressed a nicotianamine synthase …

Heavy metals are essential for basic cellular processes but toxic in higher concentrations.
This requires the precise control of their intracellular concentrations, a process known as …

Nicotianamine (NA) is a low-molecular-weight N-containing metal-binding ligand, whose
accumulation in plant organs changes under metal deficiency or excess. Although NA …

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

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

Elevated nicotianamine synthesis in roots of A rabidopsis halleri has been established as a
zinc (Zn) hyperaccumulation factor. The main objective of this study was to elucidate the …

Nickel is an essential nutrient for plants. However, the amount of Ni required for normal
growth of plants is very low. Hence, with the level of Ni pollution in the environment …

Nicotianamine synthase (NAS) catalyzes the trimerization of S-adenosylmethionine to form
one molecule of nicotianamine (NA). NA is present in all the plants; it chelates metal cations …

Plant metal hyperaccumulator species are widely used as models to unravel the heavy
metal tolerance and hyperaccumulation mechanisms. Thlaspi caerulescens is capable of …
