To find why water hyacinth accumulates the toxic heavy metal ion Cd^<2+>, the plant was cultivated in a mineral medium supplemented with Cd^'<+2>. Cd accumulated in thc roots against the concentration gradient, mostly as a soluble form in the cytoplasm. Chromatography with Sephadex G-25 and G-50 columns showed that the accumulated Cd was present in two forms with mol wt of2,300 and 3,000. The components carrying Cd showed a high ratio of absorbance at 254 nm to that at 280 nm, which suggests that they resemble marnmalian Cd-thioneins. These components were not detected in the roots of water hyacinth cultivated in the absence of Cd^<2+> jndicating that they are formcd in response to the Cd^<2+> supplement.
