AtMHX is an Arabidopsis tonoplast transporter that can exchange protons with Mg2+ and Zn2+ ions. This transporter, which may play a role in ion homeostasis of plants, is encoded by a single gene in Arabidopsis. The molecular mechanisms that regulate the expression of this transporter are practically unknown. While AtMHX transcript can be easily visualized,(More)
Expression of AtMHX, an Arabidopsis vacuolar metal transporter, is repressed by the 59 untranslated region of its gene Abstract AtMHX is an Arabidopsis tonoplast transporter that can exchange protons with Mg 21 and Zn 21 ions. This transporter , which may play a role in ion homeostasis of plants, is encoded by a single gene in Arabidopsis. The molecular(More)
