Schematic representation of the yqgB and yqfZ genes in B. thuringiensis strain 407 Cry− and B. cereus strain ATCC 14579. The mini-Tn10 insertion in the B. thuringiensis yqgB gene is indicated. Potential stem-loop structures are represented. The segments indicate the DNA fragments used to construct the lacZ plasmid transcriptional fusions.
