title: [Transformation of Bt-CpTi fusion protein gene to cabbage (Brassica oleracea var. capitata) mediated by Agrobacterium tumefaciens and particle bombardment].
abstract: Bt-CpTI fusion protein gene was transferred to the explants of hypocotyl, cotyledon with petiole and shoot apex of cabbage (Brassica oleracea L. var. capitata) variety "Zhonggan No 8" via Agrobacterium tumefaciens and particle bombardment, and 13 kanamycin-resistant plants were obtained. PCR and Southern blotting hybridization verified that all these plants of the kanr plants of type I regenerated from hypocotyl and cotyledon with petiole mediated by A. tumefaciens were transgenic plants, 2 karr plants of type II stemed from shoot apex mediated by A. tumefaciens were "false-positive"plants and one of 2 kanr plants of type III regenerated from shoot apex via particle bombardment was non-transformed plants. It was showed that part of transgenic plants had high activity of trypsin inhibitor and strong resistance to resist common cabbage worm through the analysis of CpTI relative capacity and insect-resistant test.
