Evidence for nickel/proton antiport activity at the tonoplast of the hyperaccumulator plant Alyssum lesbiacum.

Abstract:

The mechanism of nickel uptake into vacuoles isolated from leaf tissue of Alyssum lesbiacum was investigated to help understand the ability of this species to hyperaccumulate Ni. An imaging system was designed to monitor Ni uptake by single vacuoles using the metal-sensitive fluorescent dye, Newport Green. Nickel uptake into isolated vacuoles from leaf tissue of A. lesbiacum was enhanced by the presence of Mg/ATP, presumably via energisation of the vacuolar H(+)-ATPase (V-ATPase). This ATP-st...
