Induction of Manduca sexta Larvae Caspases Expression in Midgut Cells by Bacillus thuringiensis Cry1Ab Toxin

Figure 4

Accumulation of cas-1 mRNA in response to LC₂₅ and LC₅₀ doses of Cry1Ab in M. sexta midgets. (a) shows analysis the relative expression of cas-1 or cas-3 over rsp3 constitutive gene induced in control larvae (black bars) or after larvae intoxication with LC₂₅ toxin dose (gray bars) or LC₅₀ toxin dose (white bars). (b) shows the changes in fold expression of cas-1 or cas-3 after Cry1Ab intoxication compared to their expression in control larvae, fed with normal diet. Gray bars, LC₂₅ toxin dose and white bars, LC₅₀ toxin dose.
