| Description | Thlaspi caerulescens J&C Presl has been reported to have a great potential for the extraction of Zn from metalliferous soils (Reeves and Brooks, 1983; Brown et al., 1994; Brown et al., 1995a). The identification of this and several other metal hyper-accumulator plant species (Brooks et al., 1977) demonstrates that the genetic potential exists for successful phytoremediation of contaminated soils. In support of this, Brown et al. (1995b) reported that T. caerulescens grown in hydroponic medium accumulated more than 25,000 μg Zn $g^{-1}$ in shoots before any shoot biomass reduction occurred. Despite its ability to accumulate high levels of zinc and other metals in the shoot, the use of T. caerulescens for commercial scale soil remediation is severely limited by its small size and slow growth (Ebbs et al., 1997). The transfer of zinc-hyperaccumulating properties from T. caerulescens into high biomass producing plants has been previously suggested as a potential avenue for making phytoremediation a commercial technology (Brown et al., 1995a). Progress in this area, however, is hindered by a lack of understanding of the fundamental mechanisms involved in zinc transport and accumulation in roots and shoots.
