Description
| - Fractionation of species of Cd, Cu, Mo, Ni and Zn in extracts of rye seedlings (grown up in both normal and Cd2+-enriched medium) and rye flour were performed by SEC/ICPMS method. Majority of Cu, Zn and Ni in all samples is bound in a 1-2 kDa fraction. Mo in all samples occurs in a fraction of Mr of 3 kDa. During five days of cultivation in a solution of 30 mol l-1 Cd2+ the plants accumulated as much as 5 mg kg-1 of Cd, but its soluble portion represents only 12-15%. Prevailing portion of Cd complexes is involved in a fraction of 3 kDa, while the minor part occurs in a fraction of 20 kDa. The speciation of elevated Cd in plants differs from that of other metals present at a physiological level. The metal-rich fractions of extracts of all samples (i.e. those of Mr of 1-2 kDa) were refined by immobilised metal affinity chromatography. Isolated ligands of trace elements are peptides rich in dicarboxylic amino-acids.
