摘要
By means of Agrobacterium-mediated transformation, 43 kanamycin-resistant buds of Chinese cabbage were got. PCR, PCR-Southern blot and dot blot analysis were used to identify and characterize the putative transgenic plants. 26 plants had the predicted bands of the fragment of npt Ⅱ gene. Insect bioassays of 4 transformants showed that toxic protein had been translated and the translation levels were different among these transformants.
