Chromium Toxicity and Tolerance in Plants
In the environment, chromium (Cr) exist mainly in two oxidation states, i.e. hexavalent Cr (CrVI) and trivalent Cr (CrIII). CrVI is the most importunate in the soil and is highly toxic to plants. Plant lacks transporters for Cr as it is a nonessential heavy metal. However, the transporters that transport sulfate also helps in the uptake of Cr.
