Abstract

Previous studies revealed that chitinase could enhance the insecticidal activity of Bacillus thuringiensis and it has been used in combination with B. thuringiensis widely. However, the expression of B. thuringiensis chitinase is rather low and needs induction by chitin, which limits its field application. It would make sense to constitutively express the chitinase at a sufficiently high level to offer advantages in biological control of pests. In this study, a signal peptide-encoding sequence-deleted chitinase gene from B. thuringiensis strain 4.0718 under the control of dual overlapping promoters plus Shine–Dalgarno sequence and terminator sequence of cry1Ac3 gene was cloned into shuttle vector pHT315 and introduced into an acrystalliferous B. thuringiensis strain CryB. The recombinant plasmid was stably maintained over 240 generations in CryB. Chitinase was overexpressed within the sporangial mother cells in the form of spherical crystal-like inclusion bodies. The chitinase inclusions could be solubilized and exhibit chitinolytic activity in 30 mmol l−1 Na2CO3–0.2% β-mercaptoethanol buffer at a wide range of alkaline pH values, and what’s more, the chitinase inclusions potentiated the insecticidal effect of Cry1Ac protoxin when used against larvae of Spodoptera exigua and Helicoverpa armigera.
