Additional Information
Statement
Reference

ScerGAL4Ir52a.PK drives expression in leg taste bristles of the tibia and tarsus. In males more cells of the tarsal segments 2 and 4 express ScerGAL4Ir52a.PK than in females. Labeled axonal projections from the prothoracic legs cross the midline in males but not in females where expression is also fainter.
