Fig. 2

Gene family composition in acroporid genomes and the higher proportion of genes in Montipora having unknown functions. Left horizontal bars indicate numbers of gene families in each genus. Vertical bars indicate numbers of gene families conserved among genera. Pie charts indicate the generic composition in a given number of gene families (vertical bars). Gene annotation was performed using BLAST searches against the Swiss-Prot database (BLASTP, E-value cutoff: 1e⁻⁵) and protein domain search with hidden Markov models against the Pfam database (InterProScan, E-value cutoff: 1e⁻³). Numbers in pie charts indicate the number of genes with similarity to either Swiss-Prot or Pfam or neither. Proportions of gene annotations were compared among gene families specific to each lineage and asterisks indicate statistical significance (Pairwise proportion test: p < 0.05). Upset plot was produced using the “UpSetR” package [79]
