Figure 2.

Summary effects (as natural logs, ln R) and 95% confidence intervals (CIs) for the influence of CPA1 overexpression on concentration of potassium ions in roots (root K⁺). Summary effects were analysed in plants exposed to NaCl stress, with the impacts of ten moderator variables on the magnitude of the treatment effect portrayed (a–j). Category lists levels (categories or subgroups) of each moderator. Change (to the right of plots) refers to raw percentage increase in root K⁺ induced by overexpression of CPA1.
