Implication of an odorant-binding protein in precopulatory behaviour and interaction with the bacterial microbiota

2023

Chemoreception allows animals to detect nutritive food and avoid toxic compounds. Volatile and non-volatile chemical compounds, which are detected by olfactory and gustatory sensory organs, can trigger feeding and reproductive behaviours in animals such as Drosophila melanogaster. Inside chemosensory organs, perireceptor proteins like odorant-binding proteins (OBPs) serve to transport odorant and tastant molecule to dedicated receptors. OBPs are not only involved in chemoreception but also in several other functions. A recent study revealed an interaction between insect microbiota and OBP expression while another one showed that microbes can promote nutrient harvesting on food. In our proje…
