UASt regulatory sequences drive expression of an inverted repeat.
Expression of Gr28bKK105653 under the control of Scer\GAL4Gr33a-GAL4 has no impact on the L-canavanine avoidance seen in wild type flies in a two-way choice behavioral assay.
Knock-down of Gr28b through expression of Gr28bKK105653 under the control of Scer\GAL4ppk.1.9 causes an overall reduction of light response of class IV dendritic arborization neurons.
