This list covers known nickel hyperaccumulators, accumulators or plant species tolerant to nickel. See also: *Hyperaccumulators table – 1 : Al, Ag, As, Be, Cr, Cu, Mn, Hg, Mo, Naphtalene, Pb, Pd, Pt, Se, Zn *Hyperaccumulators table – 3 : Pd, Pt, Pb, Pu, Ra, Se, Zn, radionuclides, hydrocarbures and organic solvents Notes * In the genus ''Alyssum'', free histamin (His) is an important Ni binding ligand that increases in the xylem proportionately to root Ni uptake. There is a close correlation between Ni tolerance, root His concentration, and ATP-PRT transcript abundance. Thus ATP-PRT expression may play a major role in regulating the pool of free His and contributes to the exceptional Ni tolerance of hyperaccumulator ''Alyssum'' species. But this is not the complete hyperaccumulator phenotype because His-(GM-)overproducing lines do not exhibit increased Ni concentrations in either xylem sap or shoot tissue.〔() Robert A. Ingle, Sam T.
