Rate: Kimura 2-parameter distance from the reconstructed ancestral sequence. nmC: Number of C>T substitutions / number of non-methylated cytosines on both DNA strands of the reconstructed ancestral ITS sequence of Ilex. mC: Number of C>T substitutions / number of methylated cytosines on both DNA strands of the reconstructed ancestral ITS sequence of Ilex. The corresponding ratios of C>T substitutions are indicated between brackets. Chi2: Chi-square homogeneity test between expected and observed C>T substitutions at methylated cytosines (ns: non significant; *, ** and ***: significant at 0.05, 0.01 and 0.001 levels, respectively).
