Approximately 0.2 % of all angiosperms are classified as metal hyperaccumulators based on their extraordinarily high leaf metal contents, for example >1 % zinc, >0.1 % nickel or >0.01 % cadmium (Cd) in dry biomass. So far, metal hyperaccumulation has been considered to be a taxon-wide, constitutively expressed trait, the extent of which depends solely on available metal concentrations in the...

AtOSA1 a member of Abc1-like family as a new factor in cadmium and oxidative stress response

Jasinski, Michal ; Sudre, Damien ; Schansker, Gert ; Schellenberg, Maya ; Constant, Signarbieux ; Martinoia, Enrico ; Bovet, Lucien

In: Plant Physiology, 2008, vol. 147, p. pp.107.110247

The analysis of gene expression in Arabidopsis thaliana using cDNA-microarrays and RT-PCR showed that AtOSA1 (Arabidopsis thaliana Oxidative Stress related Abc1 like protein) transcript levels are influenced by Cd²⁺ treatment. The comparison of protein sequences revealed that AtOSA1 belongs to the family of Abc1 proteins. Up to now, Abc1-like proteins have been identified in...
