Transcriptome profiling of genes differentially modulated by sulfur and chromium identifies potential targets for phytoremediation and reveals a complex S-Cr interplay on sulfate transport regulation in B. juncea

► A coordinated regulation of sulfate transporters may occur in response to Cr. ► Cysteine is involved in the short-time response of plants to Cr exposure. ► Potential gene targets for Cr phytoremediation have been identified.
