Transport and detoxification of cadmium, copper and zinc in the Cd/Zn hyperaccumulator plant Thlaspi caerulescens
Hyperaccumulators store most of the accumulated metal in the vacuoles of large leaf epidermal cells (storage cells). For investigating cadmium uptake, we incubated a protoplast mixture obtained by digestion of leaves of Thlaspi caerulescens (Ganges ecotype) with a Cd-specific fluorescent dye. A fluorescence kinetic microscope was used for selectively measuring Cd-uptake and photosynthesis in di...
متن کاملTandem Quadruplication of HMA4 in the Zinc (Zn) and Cadmium (Cd) Hyperaccumulator Noccaea caerulescens
Zinc (Zn) and cadmium (Cd) hyperaccumulation may have evolved twice in the Brassicaceae, in Arabidopsis halleri and in the Noccaea genus. Tandem gene duplication and deregulated expression of the Zn transporter, HMA4, has previously been linked to Zn/Cd hyperaccumulation in A. halleri. Here, we tested the hypothesis that tandem duplication and deregulation of HMA4 expression also occurs in Nocc...
متن کاملThe molecular physiology of heavy metal transport in the Zn/Cd hyperaccumulator Thlaspi caerulescens.
An integrated molecular and physiological investigation of the fundamental mechanisms of heavy metal accumulation was conducted in Thlaspi caerulescens, a Zn/Cd-hyperaccumulating plant species. A heavy metal transporter cDNA, ZNT1, was cloned from T. caerulescens through functional complementation in yeast and was shown to mediate high-affinity Zn(2+) uptake as well as low-affinity Cd(2+) uptak...
متن کاملElectroplating and characterization of Zn–Ni, Zn–Co and Zn–Ni–Co alloys
a r t i c l e i n f o Zn–Ni, Zn–Co and Zn–Ni–Co coatings were electrodeposited on mild steel from an acidic chloride bath containing p-aminobenzenesulphonic acid (SA) and gelatin. These additives changed the phase content in the coatings, most likely as a result of their adsorption at the surface of the cathode. The effect of gelatin was more pronounced than that of SA. The Faradaic efficiency ...
متن کاملMolecular physiology of zinc transport in the Zn hyperaccumulator Thlaspi caerulescens.
In this manuscript, recent research from this laboratory into physiological and molecular aspects of heavy metal (Zn) transport in the hyperaccumulating plant species, Thlaspi caerulescens is reviewed. This research is aimed at elucidating the processes that underlie the accumulation of extraordinarily high levels of Zn in the T. caerulescens shoot (up to 3% Zn dry wt.) without any associated t...
