Third Annual RCN Meeting
May 6, 2016
Atlanta, GA
Held in conjunction with the Center for Behavioral Neuroscience Symposium

There is a widespread absence in birds of an essential subunit (T1R2) of the only known vertebrate sweet receptor, raising questions about how specialized nectar feeders such as hummingbirds sense sugars. Receptor expression studies revealed that the ancestral umami receptor (the T1R1-T1R3 heterodimer) was repurposed in hummingbirds to function as a carbohydrate receptor. The changing taste receptor function thus could have enabled hummingbirds to perceive and use nectar, facilitating the massive radiation of hummingbird species.
