Maximum-likelihood phylogenetic trees using vertebrate and insect Cu,Zn-SOD sequences (A) and using hymenopteran Cu,Zn-SOD sequences (B) (SOD3, extracellular SOD; SOD1, cytoplasmic SOD). The dashed line delineates hymenopteran extracellular Cu,Zn-SODs. Numbers at corresponding nodes are bootstrap support values (500 bootstrap replicates). Numbers followed by asterisks (*) are bootstrap values for Leptopilina SOD1 nodes. Numbers followed with number symbols (#) are bootstrap values for Leptopilina SOD3 nodes. Only bootstrap support values ≥ 75% are shown. Am, Apis mellifera; Bi, Bombus ignitus; Lb, L. boulardi; Ln, Lasius niger; Nv, Nasonia vitripennis.
