Expression of the mussel (Mytilus galloprovincialis) CTL gene family. The same phylogenetic analysis of Mytilus galloprovincialis C-type lectin-like proteins (CTLs) shown in Figure 3A is included here, along with the expression level of each CTL protein. The maximum level of expression that each protein reached in the digestive gland (DG), gills (G), hemocytes (H), mid-trochophore larvae (L), and mantle (M) across the analyzed SRA transcriptomic datasets (Supplementary File S2) is shown. Colors in the phylogenetic analysis show the orthology subfamilies identified in Figure 3. For example, subfamily “A”, conserved at the Bivalvia level, was mainly expressed in digestive glands and gills with almost no expression outside of mucosal tissues.
