Speciation of non-covalent nickel species in plant tissue extracts by electrospray Q-TOFMS/MS after their isolation by 2D size exclusion-hydrophilic interaction LC (SEC-HILIC) monitored by ICP-MS

Archive ouverte | Ouerdane, Laurent | CCSD

An original approach based on successive size-exclusion and hydrophilic interaction HPLC (HILIC) was developed to purify traces of Ni species from a plant aqueous extract. The degree of purity achieved was for the first time suffi...

Nicotianamine over-accumulation confers resistance to nickel in Arabidopsis thaliana

Archive ouverte | Pianelli, K. | CCSD

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 cDNA (TcNAS1) isolated from the polymetallic...
