Cladogram of selected protein sequences of insect β-1,3-glucanases, and β-1,3-glucan binding proteins. Branches are statistically supported by bootstrap analysis (cutoff 70%). The blue branches discriminate the monophyletic sequences of the insects that have the conserved catalytic glutamates; the green branches discriminate the paraphyletic group of sequences that do not have the conserved catalytic residues. The bootstrap values were obtained from the analysis of 10,000 replicates, using the Neighbor-Joining algorithm (MEGA software 5.05). Consensus phylogenetic tree used sequences of: Anopheles gambiae (AGAP002798-PA, AGAP002799-PA, AGAP002796-PA, AGAP006761-PA, AGAP012409-PA), Anopheles christyi (ACHR004102-RA, ACHR005689, ACHR008721-RA, ACHR001881-RA, ACHR009179-RA), Anopheles darlingi (ADAR007290-PA, ADAR007286-PA, ADAR006526-PA, ADAR009199-PA), Anopheles dirus (ADIR003516-RA, ADIR010616-RA, ADIR003518-RA, ADIR003625-RA, ADIR000553-RA) Anopheles epiroticus (AEPI010194-RA, AEPI009256-RA, AEPI005496-RA, AEPI002293-RA), Anopheles funestus (AFUN006014-RA, AFUN009437-RA, AFUN006016-RA, AFUN002755-RA, AFUN004083-RA), Anopheles minimus (AMIN004837-RA, AMIN003902-RA, AMIN003903-RA, AMIN003900-RA, AMIN010081-RA, AMIN008919-RA), Anopheles quadriannulatus (AQUA008516-RA, AQUA009400-RA, AQUA009402-RA, AQUA003848-RA, AQUA014348-RA), Anopheles stephensi (ASTE003966-RA, ASTE009324-RA, ASTE009326-RA, ASTE010371-RA, ASTE004573-RA), Culex quinquefasciatus (XM_001845911.1, XM_001845228.1, XM_001845913.1, XM_001845759.1, JF907421.1, XM_002135149.1, XM_001845915.1, XM_001847484.1, XM_001847484.1, XM_001845910.1, XM_001845757.1, XM_001864211.1, XM_001845229.1), Phlebotomus papatasi (PPATMP000880-PA, PPATMP002587-PA, PPATMP002588-PA, PPATMP010440-PA), Rhodnius prolixus (RPRC011769-PA, RPRC003210-PA, ABU96697.1), Simulium vittatum (EU930267.1), Anopheles arabiensis (ACN38171.1, CAO83421.1), Anopheles bwambae (ABU80038.1), Anopheles melas (ABU80011.1), Anopheles merus (ABU80005.1, AAZ08489.1, AAZ08502.1), Ochlerotatus triseriatus (ACU30929.1), Phlebotomus perniciosus (ADH94599.1).
