Comparative genomic analysis of Chilodontopsis depressa and phyllopharyngean and nassophorean ciliates. (A) Bubble plot showing comparison of genes controlling biological process among nassophorean (Furgasonia blochmanni, Pseudomicrothorax dubius) (1–2), synhymenian (C. depressa) (3), and phyllopharyngean (Chilodochona sp., Dysteria derouxi, Hartmannula sinica, Trithigmostoma cucullulus, Trochilia petrani, and Trochilia sp.) (4–9) ciliates based on Gene Ontology analysis by R package ggplot2. The upper and lower panels show the pathways in which up-regulated and down-regulated genes are enriched, respectively. The color bar and dot size measure the p-values of the gene enrichment and the percentage of covered genes in the corresponding pathways, respectively. (B) Bar chart showing the bias of stop codon usage among C. depressa, phyllopharyngeans, nassophoreans, and other well-annotated ciliates.
