HMA P-type ATPases are the major mechanism for root-to-shoot Cd translocation in Arabidopsis thaliana.

The New phytologist - 1 Jan 2009

Wong Chong Kum Edwin, Cobbett Christopher S

Abstract excerpt

The Zn/Cd-transporting ATPases, HMA2 and HMA4, essential for root-to-shoot Zn translocation, are also able to transport Cd. Phytochelatins (PCs) are a major mechanism of Cd detoxification through the sequestration of PC-Cd complexes in vacuoles. The roles of HMA2 and HMA4 in root-to-shoot Cd translocation and Cd tolerance were investigated in the PC-deficient, cad1-3 mutant and CAD1 backgrounds. Six lines, with...
