Additional file 2: of A repeat region from the Brassica juncea HMA4 gene BjHMA4R is specifically involved in Cd2+ binding in the cytosol under low heavy metal concentrations

Data S2. Sequence alignment of AhHMA4, AtHMA4 and TcHMA4 (cited from Courbot et al. and modified). Asterisks (*) indicate the highly conserved amino acid residues in Brassicaceae. The start of the C-terminal fragment from AhHMA4 used in the yeast tolerance assay is indicated with a bracket [29]. The 384- (underlined) and 141-amino acid (shaded in blue) partial peptides from the C-terminus of TcHMA4 used in the yeast tolerance assay. (JPG 432 kb
