 The full-length Bt toxin gene (3 534 bp) and truncated functional domains of Bt toxin gene (1 959 bp) of cry1Ac22 were amplified by PCR from Bt strain W015-1. The PCR products were ligated into plant expression vector pBI121 cutting off the ß-glucuronidase gene to make the constructs of pBI121-Cry1Ac22F and pBI121-Cry1Ac22T. The constructs carrying with Kanamycin resistant marker were transferred into T-DNA vector and then validated by restricted enzyme digestion and PCR identification. Arabidopsis transformation with the transfered T-DNA vector were performed during the flowering stage mediated by Agrobacterium tumufaciens. Transgenic Arabidopsis seeds with positive Kanamycin resistance were harvested in this research that facilitate the understanding of Bt toxin functions in plant transgenic breeding.
