Abstract excerpt
This work reports the first characterization of the natural variation of Zn tolerance and accumulation in Arabidopsis thaliana. Root and shoot growth as well as Zn content were determined for 27 A. thaliana accessions grown in vitro in presence of Zn concentrations ranging from 1 to 250 µm. All traits varied by at least twofold and their broad sense heritability varied from 0.36 to 0.91. Primary and lateral root...
