Bitter sensing is impaired in fussdelDS/fussdelDS, fussdelDS/fussMI13731 and fussdelDS.MI13731-GAL4/fussdelDS adults.
fussMI13731/fussdelDS adults have significantly less Gr33a-positive and Gr66a-positive neurons than controls.
fussdelDS/fussdelDS and fussdelDS/+ flies have a similar lifespan to controls.
fussdelDS/fussdelDS adults have a normal mushroom body morphology.
Expressing fussUAS.B under the control of Scer\GAL4fuss-MI13731-GAL4 (the intrinsic Gal4 driver of fussdelDS.MI13731-GAL4) rescues the bitter sensing impairment of fussdelDS/fussdelDS.MI13731-GAL4 adults.
