Heavy metal accumulation
Thlaspi caerulescens is a Cd and Zn hyperaccumulator. We investigated the chemical form and subcellular localization of Cd in this species and found that Cd is sequestrated in the vacuoles in the form of malate complex (Planta 221: 928-936, 2005)
Recently, we also have identified a novel QTL for shoot Cd accumulation（New Phytologist 182: 644-653, 2009）。We are currently cloning this QTL gene.
