Expression data from Arabidopsis shoots and roots

Regulation of genes in shoots and roots and Arabidopsis in response to Zn-deficiency in wild-type and hma2 hma4 mutants plants We used microarrays to determine co-regulated genes in the roots of Zn deficient wild-type plants with hma2 hma4 plants from control conditions. These co-regulated genes are candidates for regulation by a systemic signal Shoots and roots of wild-type plants grown in control and Zn-deficient conditions were harvested at 7 weeks of age, 3 weeks after transfer to -Zn or control media. Shoot and roots of wild-type and hma2 hma4 plants were harvested after 21 days of growth
