Figure 7From: Large-scale identification of odorant-binding proteins and chemosensory proteins from expressed sequence tags in insectsThe evolutionary tree of CSP. The tree was constructed by MEGA4.0 program with neighbor-joining phylogeny and the p-distances model. It was generated with 1000 bootstrap replications. The accession numbers of CSPs used in this analysis were listed in Additional File 6. The bootstrap values were given in Additional File 8-B.Back to article page
