Phylogenetic tree of CcSox5, CcSox6 and CcSox13 in comparison with SoxD proteins in other representative vertebrates using predicted amino acid sequences. The phylogenic tree was constructed by MEGA6 using the Jones–Thornton–Taylor (JTT) model based upon Neighbor-Joining method with 1000 bootstrap replicates. The scale bar is 0.1. The GenBank accession numbers are as follows: Homo sapiens: Sox5, BC060773.1; Sox6, AF309034.1; Sox13, NM_005686.2; Mus musculus: Sox5, AB006330.1; Sox6, U32614.1; Sox13, NM_011439.2; Gallus gallus; Sox5, NM_001004385.1; Sox6, XM_015286512.1; Sox13, XM_004934897.2; Bos taurus: Sox5, NM_001083471.1; Bos mutus: Sox5, XM_005897700.2; Capra hircus: Sox6, :XM_018059599.1; Oryzias latipes: Sox5, NM_001122910.1; Sox13, XM_011475310.1; Xenopus laevis: Sox5, AB682776.1; Sox6, NM_001280658.1; Sox13, NM_001087769.1; Danio rerio: Sox5, NM_001033585.1; Sox6, NM_001123009.1; Xenopus tropicalis: Sox13, XM_012963174.2; Kryptolebias marmoratus: Sox5, XM_017429903.1; Sox6, XM_017441909.1; Poecilia latipinna; Sox5, XM_015049850.1; Cynoglossus semilaevis; Sox5, XM_008315905.2; Sox6, XM_008311513.2; Sox13, XM_017036517.1; Ictalurus punctatus: Sox6, XM_017478071.1; Oncorhynchus mykiss: Sox5, FJ713023.1; Xiphophorus maculatus: Sox6, XM_005805573.1; Ictalurus punctatus: Sox13, XM_017450839.1
