Modulation of Zn/Cd P(1B2)-ATPase activities in Arabidopsis impacts differently on Zn and Cd contents in shoots and seeds.

Zn is an essential microelement for all living cells and Zn deficiency is widespread in world's population. At the same time, high Zn concentration and low Cd concentration are toxic to the environment. Both Zn and Cd are transported in planta via Zn/Cd HMA transporters.
