Figure 3

(a) Transcript and peptide sequences of H. amboinensis and H. tubifera were compared to sequences from other sponges. Alignments were conducted using Blastx for transcripts and Blastp for peptides. Heatmaps represent the percent of transcripts (left) or predicted peptides (right) with detectable sequence similarity to other sponges at an e-value threshold of 1 × 10−5 (red, high; blue, low). (b) Comparison of the number of shared and class-specific orthologous protein groups from OrthoMCL analysis. (c) Shared and species-specific orthologous protein groups in four haplosclerid sponges. (d) Gene losses in sponge lineages as estimated by EvolMap analysis. The scale bar corresponds to 500 genes. (e) Gene gains in sponge lineages as estimated by EvolMap analysis. The scale bar corresponds to 5,000 genes. EvolMap trees are rooted on O. carmela. Species names are abbreviated as follows: A. queenslandica (Aque); H. amboinensis (Hamb); H. tubifera (Htub); P. ficiformis (Pfic); E. muelleri (Emue); L. complicata (Lcom); S. ciliatum (Scil); O. carmela (Ocar).
