Odorant-binding proteins (OBPs) in insects bind to volatile chemical cues that are important in regulating insect behavior. It is hypothesized that OBPs bind with specificity to certain volatiles and may help in transport and delivery to odorant receptors (ORs), and may help in buffering the olfactory response and aid the insect in various behaviors. Honeybees are eusocial insects that perceive olfactory cues and strongly rely on them to perform complex olfactory behaviors. Here, we have identified and annotated odorant-binding proteins and few chemosensory proteins from the genome of the dwarf honey bee, Apis florea, using an exhaustive homology-based bioinformatic pipeline and analyzed the evolutionary relationships between the OBP subfamilies. Our study confirms that the Minus-C subfamily in honey bees has diverged from the Classic subfamily of odorant-binding proteins.
