Fig. 3From: Genome-wide identification and expression profiling of odorant receptor genes in the malaria vector Anopheles sinensisPhylogenetic tree of OR proteins in An. sinensis, An. gambiae, Ae. aegypti and Cx. quinquefasciatus. Conserved domains of AsOR proteins were aligned using ClustalX, and the phylogenetic tree was constructed by RAxMLv8.2.0, using the maximum-likelihood method (1000 bootstrap) based on the best fit model of JTT + I + GBack to article page
