Length and information content of 71 exons common to Pinus accessions sampled in this study. A) Exon contributions to length as proportion of total exome length. B) Exon contributions to parsimony informative sites as proportion of total exome parsimony informative sites. C) Distribution of exons in relation to length and parsimony informative sites. In A) and B) most exons are shown by functional group (i.e., atp(), psb(); number of corresponding loci indicated in parentheses) for visualization purposes. In C) all exons were treated individually (N = 71). Trendline in C) based on all exons with exception of ycf1 and ycf2 to emphasize their departure from trend in other exons.
