Table 2.
Number of Genes Showing Significant Ratio Changes in Leaf and Root for Each Genotype.
| A. kamchatica | Significant genes | % total | H ratio (ctl) | H ratio (zinc) | H ratio r2 |
|---|---|---|---|---|---|
| MUR-leaf | 68 | 0.3 | 53.8% | 53.7% | 0.94 |
| MUR-root | 309 | 1.5 | 53.6% | 53.6% | 0.93 |
| PAK-leaf | 174 | 0.9 | 52.3% | 52.3% | 0.89 |
| PAK-root | 293 | 1.5 | 52.0% | 52.3% | 0.90 |
Note.—Percent total is the number of genes showing significant ratio changes out of our total gene dataset (N = 19820 genes). H ratio ctl (before treatment) and H ratio zinc (after 48 h zinc treatment) indicates the median Arabidopsis halleri-origin expression over the Arabidopsis lyrata-origin copies for all genes in the dataset. Correlation coefficients (r2) indicate the correlation of genome wide expression ratios before and after zinc treatment. Significance for the ratio change statistic based on FDR-adjusted P < 0.05
