Expression of Kal1R159T.R161L.Scer\UAS using Scer\GAL4179Y induces lethality, delay in hatching, and defects in the head skeleton similar to expression of Kal1Scer\UAS.cAa.
At 18[o]C, expression of Kal1R159T.R161L.Scer\UAS using Scer\GAL4Bx-MS1096 induces a small reduction of the proximal-distal axis of the wing with no other visible defects. At 25[o]C, there is a stronger reduction of the proximal-distal axis of the wing and frequently a splitting of vein L4. Reduction of the L2-L3 intervein region and notching of the L3-L5 wing margin is occasionally seen.
