Table 2: Results of the distance-based redundancy analysis (dbRDA)
carried out to test the effect of population, treatment, and their
interaction on genome wide DNA methylation for each of the common garden
experiments (Overall model). The results of the permutation test (n =
9999) for the significance of each of the predictors are also shown
(Predictors).\(\ d_{\text{st}}\): pairwise distance matrix calculated
with the methylation level and variance of each cytosine in each sample.
CG-Cd: common garden comparing control and Cd-treated plants; CG-Cu:
common garden comparing control and Cu-treated plants; Df: degrees of
freedom; adj. R2: adjusted R2.
