Cry1Aa toxin induces cell necrosis in Cry1Aa toxin receptor (CryR)-overexpressing cells in dpp > GFP, CryR wing discs. (a, b) PI staining of cultured wing discs from third instar larvae expressing CryR by dpp-Gal4.dpp > GFP, CryR incubated 1 h with 100 nM Cry1Aa showed PI signal (b), while dpp > GFP, LacZ incubated with Cry1Aa did not (a).
