Molecular Characterization and Tissue Expression of Common Tobacco (Nicotiana tabacum) Cadmium Resistance Protein 2 and Metal Tolerance Protein 4 Genes
Metal Tolerance Protein 2 from N. tabacum (NtMTP2) is a tonoplast-localized Co and Ni efflux transporter. As an housekeeping protein controls optimal micronutrients concentration in the cytoplasm, and sequesters metal excess specifically in leaves.
