As a part of the systematic study of heavy metals phytoremediation, hydroponically grown Indian mustard (Brassica juncea) seedlings were selected as model eukaryotic plant system for the characterization of Zn and Cd induced tolerance in phytoindicators. 10 cultivars of Indian mustard (Brassica juncea) were grown on MS media with varying levels of Zn and Cd separately as well as in combinations. 6 days old seedlings were harvested and dissected into different organs. Each organ was further analysed for its proline content. On the basis of their tolerance (in terms of morphological parameters and biochemical parameter proline content) towards heavy metals tested, PCR-7 was found to be the most tolerable Brassica juncea cultivar.
