Experimental evidence suggests that nicotianamine (NA) is involved in the complexation of
metal ions in some metal‐hyperaccumulating plants.• Closely‐related nickel (Ni)‐and zinc
(Zn)‐hyperaccumulating species were studied to determine whether a correlation exists
between the Ni and Zn concentrations and NA in foliar tissues.• A liquid chromatography–
mass spectrometry (LC‐MS) procedure was developed to quantify the NA and amino acid
contents using the derivatizing agent 6‐aminoquinolyl‐N‐hydroxysuccinimidyl carbamate. A …

… (2007) have brought to our attention an error in the units of Table 4, where the mean
concentrations of amino acids should have read mg kg −1 and not nmol mg −1 . The correct
Table 4 is printed below. We apologize to our readers for this mistake. … Table 4 Mean
concentrations (n = 3) of amino acids, nicotianamine (NA), nickel (Ni), zinc (Zn), copper (Cu)
and iron (Fe) for the seven Thlaspi species …
