Pkcδ^e04408 indirect flight muscles exhibit abnormal myofibril structure and shorter sarcomeres in adults.

Adult Pkcδ^e04408/Pkcδ^e04408 mutant flies display no defects in operant self-learning (motor learning) in an assay measuring turning attempts in an stationary flight experimental set-up where one of the yaw torque domains (left or right) is punished by heat during the learning period prior to experimental measurements.
