Phylogenetic tree, gene structure, conserved motifs, protein function domains, and conserved modification sites of SoBSKs. A Phylogenetic tree of SoBSKs constructed by the Neighbor-Joining method. B The exon, intron, and untranslated region (UTR) organization of SoBSKs. Light pink boxes indicated UTR, yellow boxes represented exons, and lines showed introns. C Conserved motifs of SoBSKs. Various colors represented different motifs. D-F The logos showing the conserved residues in motif 1 (D), motif 6 (E), and motif 13 (F). G Function domains and conserved modification sites of SoBSKs. Kinase domain and tetratricopeptide repeat (TPR) were labeled in green and pink, respectively. Conserved modification sites were labeled with different shapes. C: Cysteine; G: Glycine; K: Lysine; R: Arginine; S: Serine; T: Threonine
