Annotation of genes predicted to have originated before and after the origin of stem-Mollusca. Proportion of genes with the functional annotations chitin binding, other gene ontology, and no predicted gene ontology are displayed for genes predicted to have originated before (inner circle) and after (outer circle) the origin of stem-Mollusca, based on phylostratigraphic analyses. Functional annotations of radula-specific (right) and all other genes included in the phylostratigraphic analyses (left) are based on Pfam annotations.
