Wing pouch enhancers mediate inputs from Notch and EGFR pathways. (A to O) Expression from argos(p)-lacZ (A to D), argos2-GFP (E to H), argos3-GFP (I to L), or argos1-lacZ (M to O) reporters in wild-type discs (A, E, I, and M) or in the presence of cic-RNAi (B, F, J, and N), HLHmβ-VP16 (C, G, K, and O), or HLHmβ (D, H, and L). (P) Quantification of argos1-lacZ reporter expression in the AMPs under the conditions indicated. Data are averages from at least 5 discs per genotype, and error bars represent standard errors of the means. Red brackets indicate the region of transgene expression, and arrows mark the L3 and L4 veins.
