Figure 6From: Expressed sequence tags from larval gut of the European corn borer (Ostrinia nubilalis): Exploring candidate genes potentially involved in Bacillus thuringiensis toxicity and resistanceExpression profiles of 41 candidate genes relevant to Bt toxicity and resistance, which include 15 trypsin-like serine protease (TP), 13 chymotrypsin-like serine protease (CP), 2 alkaline phosphatase (AK), 10 aminopeptidase (AP), and 1 cadherin-like protein (CA) genes in the midgut of one-day-old fifth-instar larvae in Cry1Ab-susceptible (S) and resistant (R) strains of ECB as determined by RT-PCR. The arrows next to the gel pictures indicate the apparently decreased (↓) or increased (↑) expression of a particular gene in Cry1Ab-resistant strain as compared with the susceptible strain of ECB. The ribosomal S3 (RPS3) gene was used as a reference gene. At least two biological replications were used for each primer pair. The sequences of PCR primers used in this study were given in Appendix A.Back to article page
