Relationships of bHLH Orange proteins from deeply branching arthropods and lophotrocozoan groups. Bayesian phylogram of representative bHLH-orange domain proteins reconstructed using the WAG model of protein evolution. bHLH Orange domain proteins from Chelicerates (PTEP, Parasteatoda tepidariorum; LHE, Latrodectus hesperus; ISCW, Ixodes scapularis; CSCU, Centruroides exilicauda; XP, Metaseiulus occidentalis) Insects (honeybee, GB; Drosophila; gene names) a myriapod, Strigamia maritima (smar_), and an Annelid, Platynereis (AGS identifiers) with well characterised HES genes [61]. Strigamia contains E(spl) related bHLHO proteins, but these form a separate clade to those in insects and Crustacea that make up the E(spl)-C
