TLDR
The high metal accumulation by some cultivars of B. juncea suggests that these plants may be used to clean up toxic metal-contaminated sites in a process termed phytoextraction.Abstract:
A small number of wild plants which grow on metal contaminated soil accumulate large amounts of heavy metals in their roots and shoots This property may be exploited for soil reclamation if an easily cultivated, high biomass crop plant able to accumulate heavy metals is identified Therefore, the ability of various crop plants to accumulate Pb in shoots and roots was compared While all crop Brassicas tested accumulated Pb, some cultivars of Brassica juncea (L) Czern showed a strong ability to accumulate Pb in roots and to transport Pb to the shoots (1083 mg Pb/g DW in the roots and 345 mg Pb/g DW in the shoots) B juncea was also able to concentrate Cr{sup -6}, Cd, Ni, Zn, and Cu in the shoots 58, 52, 31, 17, and 7 fold, respectively, from a substrate containing sulfates and phosphates as fertilizers The high metal accumulation by some cultivars of B juncea suggests that these plants may be used to clean up toxic metal-contaminated sites in a process termed phytoextractionread more

TL;DR: To increase both biomass production and metal accumulation of short rotation coppice, two strategies are proposed: (i) in situ selection of the best performing clones and (ii) bioaugmentation of these clones with beneficial plant-associated bacteria.

Effect of Bioaccumulation of Cs and Sr Natural Isotopes on Foliar Structure and Plant Spectral Reflectance of Indian Mustard (Brassica juncea)
TL;DR: In this article, the capacity of Indian mustard for uptake and accumulation of Cs and Sr natural isotopes was evaluated by spectral reflectance, and the results showed that the Cs accumulation affected the pigment concentration and internal structure of the leaves and spectral characteristics of plants.

Comparison of tolerance of Brassica juncea and Vigna radiata to cadmium
TL;DR: In both species, Cd was accumulated more in roots than in shoots, with higher accumulation in Indian mustard than in mung bean, and a difference between species was also found in Cd uptake and accumulation.
