Constitutively high expression of the histidine biosynthetic pathway contributes to nickel tolerance in hyperaccumulator plants.

Abstract

Plants that hyperaccumulate Ni exhibit an exceptional degree of Ni tolerance and the ability to translocate Ni in large amounts from root to shoot. In hyperaccumulator plants in the genus Alyssum, free His is an important Ni binding ligand that increases in the xylem proportionately to root Ni uptake. To determine the molecular basis of the His response and… (More)
