Figure 2From: Increased Bacillus thuringiensis δ-endotoxin Cry3Aa toxicity against longhorned beetle by fusing to peptide specifically binding to beetle Cx-cellulaseConcentration of Cry3Aa in A. germari Hope larvae after feeding with Cry3Aa and the Cry3Aa fusion proteins. a, Cry3Aa was measured in larval excretions collected at 2, 4, 6, and 8 h after feeding. The Cry3Aa content peaked at 4 h after feeding with Cry3Aa, whereas the peak was observed at 6 h after feeding with the Cry3Aa fusion proteins. b, Cry3Aa was measured in larval midgut extractions at 4 h after feeding. The concentration of Cry3Aa in the midgut extracts was higher after feeding with the fusion proteins, compared with non-modified Cry3Aa.Back to article page
