Signals of adaptation of the A. thaliana editomes. (A) The numbers of observed nonsynonymous and synonymous editing sites were compared to the random expectation under neutral evolution. P value was calculated by Fisher’s exact test. ***, P < 0.001. (B) Comparison of editing levels of nonsynonymous and synonymous editing sites in various tissues of A. thaliana. Error bars represent standard error of mean. P values were calculated with Wilcoxon rank sum tests. ***, P < 0.001. Chloroplast and mitochondrial editing sites were shown respectively. (C) Heatmaps displaying the conservation of editing levels of individual editing sites. Nonsynonymous editing sites obviously have less tissue-specificity than synonymous editing sites. (D) Pairwise differential editing sites (DES) between A. thaliana tissues. Nonsynonymous and synonymous sites were shown separately
