Sugar perception in honeybees.

Honeybees () need their fine sense of taste to evaluate nectar and pollen sources. Gustatory receptors (Grs) translate taste signals into electrical responses. experiments have demonstrated collective responses of the whole Gr-set.

CRISPR/Cas 9-Mediated Mutations as a New Tool for Studying Taste in Honeybees.

Honeybees rely on nectar as their main source of carbohydrates. Sucrose, glucose, and fructose are the main components of plant nectars. Intriguingly, honeybees express only 3 putative sugar receptors (AmGr1, AmGr2, and AmGr3), which is in stark contrast to many other insects and vertebrates.
