Figure 4.
(A) qPCR analysis using Gal4 or EGFP primers showing the midgut-specific expression of ET-Gal4>UAS-EGFP transgene at 72 h PE. ND means non-detected. RNA samples were extracted from midgut (MG), fat bodies (FB), ovaries (OV), and Malpighian tubules (MT) at 72 h PE. Analyses were performed by means of qPCR using specific probes (Table S2). (B) Topical JH application induces premature expression of EGFP in midgut (MG) of the ET-Gal4>UAS-EGFP transgenic line (JH). Application of acetone (solvent) served as a control. Images were obtained using a Leica M165FC fluorescent stereomicroscope with LAS V4.0 software. Scale bar: 1 mm.
