KEGG pathways for Wnt (a), apoptosis (b), and Notch (c) signalling pathways, showing presence of majority of components in our transcriptome, in green. Where components were not identified by the KEGG SBH annotation process, this is indicated in orange (where these are not known in the Spiralia to date) or red (when these would be expected). Absence may be real or the result of marked sequence divergence between genes in our dataset and those orthologs in the KEGG database
