Ancient WGD Identification (IAsα) and Timing of the Event in Acropora

(A) Frequency distribution of dS values for paralogous gene pairs in five Acropora and one Astreopora species showing that a WGD event occurred in Acropora. Similar peaks (dS value: 0.1–0.3) in dS distributions of the five Acropora lineages indicate that a WGD event occurred in Acropora. (Light red, A. digitifera; light yellow, A. echinata; light green, A. gemmifera; light blue, A. subglabra; light purple: A. tenuis; light cyan, Astreopora sp1).

(B) Hypothetical tree topology of duplicated genes in the Acroporidae and the phylogeny of one duplicated gene (alpha-protein kinase 1-like). The phylogenetic tree shows gene retention, loss, and duplications following WGD.

(C) Co-linear gene alignments of Astreopora sp1 and A. tenuis on scaffolds. The gray links show orthologs between Astreopora sp1 and A. tenuis.
