All HMA proteins of P. trichocarpa (12), A. thaliana (8), and O. sativa (9) were divided into two distinct subfamilies. The phylogenetic tree was constructed using MEGA 5.0 using the neighbor-joining (NJ) method with 1000 bootstrap replicates. Green represents the Zn/Cd/Co/Pb subgroup; pink indicates the Cu/Ag subgroup.
