A novel insecticidal gene cry1Ah was cloned from Bacillus thuringiensis isolate BT8 previously for plant genetic engineering
improvement. Truncated active Cry1Ah toxin has a toxicity level similar to that of the full-length Cry1Ah toxin. In this
study, plant expression vector pMhGM harboring truncated cry1Ah gene was transformed into maize (Zea mays L.) immature
embryos by Agrobacterium tumefaciens-mediated transformation at which maize alcohol dehydrogenase matrix attachment
regions (madMARs) were incorporated on both sides of the gene expression cassette to improve gene expression
