Fig. 3From: Transcriptome sequencing reveals genome-wide variation in molecular evolutionary rate among fernsNumber of loci for which a given dN/dS model best explains the data (p < 0.05). ωV = estimated average dN/dS for vittarioid ferns; ωB = estimated dN/dS for the branch subtending vittarioids; ωT = estimated dN/dS for all taxa and branches excluding vittarioids and the subtending branch.
