The phylogeny and expression patterns of BmCOEs. Bootstrap values > 70% are shown. The solid black circles corresponding to cDNA, EST, tissue microarray and RT-PCR column indicate that these genes have expression evidence. The genes with grey font are that they had no probes in microarray dataset. The underlined α-esterases mean that they had substitutions in the catalytic triad.
