Fig. 5. The effect of ectopic expression of BR-Z isoforms in the prothoracic gland (PG) cells on Drosophila molts. (A–D) Larvae with ectopic expression of one of the BR isoforms in the PG cells under the control of the P0206 Gal4 driver were fed either standard diet or 20-hydroxyecdysone (20E) diet as described in Materials and methods. Each bar represents an average of at least three repetitions of the percentage of successful molting (mean ± S.D.). The total number of animals for each observation is shown in the bar.
