Long-Distance Water Transport in Aquatic Plants.

abstract：:PIB-type ATPases transport heavy metal ions (Cu+, Cu2+, Zn2+, Cd2+, Co2+, etc.) across biological membranes. Several members of this subfamily are present in plants. Higher plants are the only eukaryotes where putative Zn(2+)-ATPases have been identified. We have cloned HMA2, a PIB-ATPase present in Arabidopsis (Arabi...
