UASt regulatory sequences drive expression of an inverted repeat.
The expression of OtopLaKK112648 under the control of Scer\GAL4elav-C155 results in decreased repulsion to HCl, tartaric acid and glycolic acid, assessed in proboscis extension response assays. Similarly, expression under the control of Scer\GAL4Gr66a.PD leads to decreased repulsion to HCl.
Expressing OtopLaKK112648 under the control of Scer\GAL4Poxn.14 leads to a severe impairment in the preference for low-acid foods.
