In the Report Engineering Modified Bt Toxins to Counter Insect Resistance, there were irregularities in the preparation of gel figures for Fig. 2. The authors have supplied replications, which are shown below. The conclusions of the paper are unaffected.

Figure 2. Effect of RNAi on cadherin protein expression in M. sexta larvae. Western blots were tested for the M. sexta cadherin protein (BT-R1) and for an 80-kD brush-border membrane vesicle protein (BBMV). Lanes 1 to 4: Control larvae injected with water only and fed a diet without toxin. Lanes 5 to 12: Larvae injected with 1 μg of BT-R1 dsRNA and fed a diet with 20 ng of Cry1Ab/cm2 (only surviving larvae were analyzed). Efficiency of cadherin silencing is reported in the revised supplementary material, along with replications of supplementary figure S2.
