Figure 3From: Bacillus thuringiensis subsp. kurstaki HD1 as a factory to synthesize alkali-labile ChiA74∆sp chitinase inclusions, Cry crystals and spores for applied use Relative expression level of chiA74 Δ sp transcripts in 4Q7 at different times. Expression of the endochitinase gene was regulated by its native promoter (white rectangles) or the strong chimeric sporulation-dependent cytA-p/STAB-SD promoters (gray rectangles).Back to article page
