Introduction of ZIP family transporter gene homologues TjZnt1 and TjZnt2 (metal ion transporters) into yeast strains conferred increased Ni(II) tolerance in that species. The action of ZIP family transporter homologues, however, could not explain the Ni resistance of yeast strains transformed with T...
