[Structure and function of heavy metal transporter P(1B)-ATPase in plant: a review].
The regulation of the heavy-metal accumulation in vivo for plant survival is very complex. The metal cation transporter plays key roles in the metabolic process. P(1B)-ATPases are the only subgroup of P-ATPases that contribute to heavy metal homeostasis presented in most organisms. Arabidopsis thaliana contains eight genes encoding P(1B)-ATPases. The current reports show that the functions of P(1B)-ATPases are involved in maintaining metal homeostasis, transporting and detoxification in plants. P(1B)-ATPases not only mediated metal ion mobilization and uptake in roots, but also contribute to the metal transport, storage and tolerance in shoots, especially in heavy metal hyperaccumulators. In this paper, we reviewed and discussed the evolution, classification, structure and function of P(1B)-ATPases in plants. HMAs-transgenic manipulation could be a feasible approach for phytoremediation and mineral nutrition fortification.
