The ZIF2 transporter affects root-shoot partitioning in <i>Arabidopsis</i>.

<p>Zn concentration, expressed on a dry weight (DW) basis, in the shoot (upper panel) and root (middle panel), as well as the corresponding shoot/root ratio (lower panel), of 21-d old seedlings of the wild type (Col-0), the <i>zif2-1</i> mutant and <i>ZIF2</i>-overexpressing lines (<i>ZIF2.1</i>OX2 and <i>ZIF2.2</i>OX1) grown on control medium (30 µM Zn²⁺) or under excess Zn supply (125 and 250 µM Zn²⁺). Bars represent means ± SD (<i>n</i> = 4). Different letters indicate statistically significant differences between genotypes under each condition (<i>P</i><0.05; Student's <i>t</i>-test).
