Cnidarian CaTX/CrTX toxin family gene tree. ML topology of all known homologs of the CaTX/CrTX toxin family in cnidarian taxa from NCBI Genbank and transcriptome components of A. alata in this study. Assumes the WAG + G + F model of amino acid evolution, as specified as most appropriate by ProtTest v. 3.2. Shimodaira-Hasegawa-like branch support indices are shown at each node. Tissue-specific expression patterns correspond to transcripts primarily enriched in the tentacle (in blue) and gastric cirri (in beige). In A. alata, the expression of genes annotated as the CaTX-A homolog is specific to the tentacle (and pedalium base) sample (comp70167, comp71168), while genes annotated as the CrTX-A homolog are specific to gastric cirri and a single tentacle gene (comp76495). Additionally, the expression of a single gene (comp76989) annotated as both CrTX and CaTX is tentacle specific
