Résumé

The Arabidopsis thaliana metal tolerance protein 1 (MTP1) of the cation diffusion facilitator family of membrane transport proteins can mediate the detoxification of Zn in Arabidopsis and yeast. Xenopus laevis oocytes expressing AtMTP1 accumulate more Zn than oocytes expressing the AtMTP1_D94A mutant or water-injected oocytes. An AtMTP1-GFP fusion protein localizes to the vacuolar membrane in root and leaf cells. The analysis of Arabidopsis transformed with a promoter-GUS construct suggests that AtMTP1 is not produced throughout the plant, but primarily in the subpopulation of dividing, differentiating and expanding cells. RNA interference-mediated silencing of AtMTP1 causes Zn hypersensitivity and a reduction in Zn concentrations in vegetative plant tissues.
