Functional and regulatory analysis of the Arabidopsis thaliana CAX2 cation transporter.

Plant molecular biology - 1 Dec 2004

Abstract excerpt

The vacuolar sequestration of metals is an important metal tolerance mechanism in plants. The Arabidopsis thaliana vacuolar transporters CAX1 and CAX2 were originally identified in a Saccharomyces cerevisiae suppression screen as Ca2+/H+ antiporters. CAX2 has a low affinity for Ca2+ but can transport other metals including Mn2+ and Cd2+. Here we demonstrate that unlike cax1 mutants, CAX2 insertional mutants...
