Cation diffusion facilitator (CDF) proteins belong to a family of heavy metal efflux transporters that might play an essential role in homeostasis and tolerance to metal ions. We investigated the subcellular localization of Arabidopsis thaliana AtMTP1, a member of the CDF family, and its physiological role in the tolerance to Zn using MTP1-deficient mutant plants. AtMTP1 was immunochemically detected as a 43 kDa protein in the vacuolar membrane fractioned by sucrose density gradient… CONTINUE READING
