Expressed vomeronasal type-1 receptors (V1rs) in bats uncover conserved sequences underlying social chemical signaling

In mammals, social and reproductive behaviors are mediated by chemical cues encoded by hyperdiverse families of receptors expressed in the vomeronasal organ. Between species, the number of intact receptors can vary by orders of magnitude. However, …

The Molecular Evolution of Bat Chemosensory Pathways Reveals Sensory Innovation and Loss

Chemosensation detects environmental chemical cues and mediates many behaviors directly related to fitness (e.g. finding food, mates). Mammals have a secondary chemosensory system known as vomerolfaction that is primarily attributed to detecting …

Trpc2 pseudogenization dynamics in bats reveal ancestral vomeronasal signaling, then pervasive loss

Comparative methods are often used to infer loss or gain of complex phenotypes, but few studies take advantage of genes tightly linked with complex traits to test for shifts in the strength of selection. In mammals, vomerolfaction detects chemical …
