TLDR
In this paper, azetidine-2-carboxylic acid has been isolated from seeds of Fagus silvatica L. (beechnuts) and its structures have been established by PMR- and 13C-NMR-spectroscopy and by synthesis from l -azetidine 2-CARBOYCLIC acid.About:

Metal ion ligands in hyperaccumulating plants
TL;DR: Ligands that have been reported to play a role in sequestering, transporting or storing the accumulated metal, including citrate, histidine and the phytosiderophores are focused on.

Nicotianamine: mediator of transport of iron and heavy metals in the phloem?
Udo W. Stephan,Günter Scholz +1 more
TL;DR: In this article, it was shown that the unusual amino acid nicotianamine (NA) is needed for normal distribution of heavy metals in young growing tissues fed via the phloem.
Journal ArticleDOI
The nicotianamine molecule is made-to-measure for complexation of metal micronutrients in plants
TL;DR: In this article, the metal-NA complexes were calculated based on the complex formation constants and on acid dissociation constants of the amino acid nicotianamine (NA) and showed their stability at neutral or weak alkaline pH of cytoplasm and sieve tube sap.

Nicotianamine ‐ a common constituent of strategies I and II of iron acquisition by plants: A review
TL;DR: Nicotianamine (NA) is present in all multicellular plants hitherto investigated as discussed by the authors and is essential for the proper function of Fe(II) dependent processes such as the regulation of iron deficiency response mechanisms, iron enzymes, and phloem loading/unloading of iron.

Nicotianamine is a major player in plant Zn homeostasis
TL;DR: Support for the existence of Zn–NA complexes in planta has been obtained in rice, Arabidopsis thaliana and the Zn hyperaccumulating plant A. halleri.
