Putative L. polyphemus PERIOD (PER) proteins. Alignment of L. polyphemus (L. polyphemus) PERa to L. polyphemus PERb and PERc using CLUSTAL Omega. Symbols immediately below sequence indicates functional similarity of residues between protein orthologs. “*” Indicates identical residues, “:” Indicates residues with strongly similar properties, “.” Indicates residues with weakly similar properties. Green shows bHLH domain, Blue shows PAS domain, Red shows PAC domain, Grey shows Period C domain.
