Abstract
Several members of Brassicaceae family are well known metal accumulators. High metal translocation from their roots to above ground shoots without showing any phytotoxic symptoms make them potential candidates for remediation of various metal/metalloid contaminated areas. These plants tolerate the high amount of accumulated heavy metals by sequestering them into vacuoles of aboveground parts especially leaves. This is partly done by overexpression of specific metal transporters in different tissues from metal uptake in the root and shoot up to the storage sites (non sensitive) in the leaf. Hyperaccumulation and hypertolerance traits associated with Brassicaceae ignited interests in scientific community to understand and investigate the range of mechanisms and omics in these plants with relation to accumulation of metals and their detoxification. In this chapter we will try to discuss the mechanism of heavy metal uptake in Brassicaceae and their tolerance and detoxification pathways in these plants.
