a Correlation between the abundance of conserved protein domains (Y axis) and their level of enrichment in the dispensable mussel genes (X axis). Each dot represents a conserved protein domain, with specific examples highlighted within boxes. Domains shown in red and blue are under- and over-represented, respectively, in the dispensable gene set compared to the core genome. b Total number of unique potentially functional sequence variants and pseudogenes, and average number of unique functional variants per genome for the six families of antimicrobial peptides analyzed (myticins, mytilins, mytimycins, myticalins, mytimacins, and big defensins). c Schematic organization of the precursor proteins of the six AMP families displayed in panel b. SP: signal peptide; ProP: propeptide region; EF-hand: EF-hand domain; lc-MP: linear cationic mature peptide; ah-MP: alpha helical mature peptide; cr-MP: cysteine-rich mature peptide
