内容記述 |
Ni homeostasis is essential for plant cell activity, but the mechanisms of Ni-transport and delivery are unknown. To elucidate the role of ZIP and NRAMP metal-transporters for Ni²⁺-transport and homeostasis, we cloned their homologous genes from the Ni hyperaccumulator Thlaspi japonicum, and investigated their Ni-transporting abilities by expression in yeast. The deduced amino acid sequences of the two Zip transporter genes (TjZnt1, TjZnt2) and one Nramp transporter gene cloned had high homologies with TcZNT1 and TcZNT2 of Thlaspi caerulescens and AtNRAMP4 of Arabidopsis thaliana, respectively, and were predicted as integral membrane proteins with 6 or 12 transmembrane domains. TjZNT1 and TjZNT2 had two long histidine-rich domains in the putative cytoplasmic domain between transmembrane domains III and IV. TjNRAMP4 conserved a consensus transporter motif between transmembrane domains VIII and IX. The yeast transformed with TjZNT1 or TjZNT2 showed a marked increase in Ni²⁺ tolerance with the gene expression. In contrast, the expression of TjNramp4 caused elevation of Ni²⁺ sensitivity and Ni²⁺ concentration. These data suggest that ZIP/NRAMP transporters participate in Ni²⁺ homeostasis of Ni hyperaccumulator plants. TjZNT1 had Zn²⁺-, Cd²⁺- and Mn²⁺-transporting abilities and TjZNT2 also had Zn²⁺- and Mn²⁺-transporting abilities, but TjNRAMP4 could transport Ni²⁺ but not Zn²⁺, Cd²⁺ or Mn²⁺. |
