Analyses of orthogroups and gene family expansion/contraction within ciliates. A Upset plot of intersecting sets of orthogroups in six hypotrichous ciliates. B Phylogenomic tree with divergence time, and gene family expansion/contraction for Pseudourostyla cristata and 16 other species. The numbers at nodes indicate the number of expanded (blue) and contracted (orange) gene families at different evolutionary time points. Numbers following species names represent expanded and contracted gene families for species alone. MRCA, most recent common ancestor
