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.
Alpine pennycress or «Alpine Pennygrass» is also found as «Alpine Pennycrest» in (some books).
