Fig. 3From: Induction of rapid and selective cell necrosis in Drosophila using Bacillus thuringiensis Cry toxin and its silkworm receptorSynergistic effect of simultaneous expression of CryR and BtR175 on Cry1Aa-induced toxicity. Propidium iodide (PI) staining of wing discs from third instar larvae overexpressing BtR175 by en-Gal4 and CryR by WP-QF2 incubated for 1 h with 50 nM Cry1Aa. Genotype is w; en-Gal4, UAS-GFP/+; WP-QF2, UAS-BtR175/QUAS-CryR. PI signals were stronger in the posterior half of the wing pouch where both BtR175 and CryR were expressed.
