Phylogeny of the OBP protein family in Apis mellifera. An unrooted tree was constructed with aligned protein sequences from the honey bee using neighbor-joining. The OBP protein family is composed of two color-coded subgroups, the C-minus subfamily (dark gray) on chromosome 15 and OBPs clustered on chromosome 9 (light gray). The stars and squares indicate nodes with 95% and 80%–95% bootstrap supports respectively.
