Abstract

Using hypocotyl segments of aseptic seedlings of cabbage (Brassica oleracea var. capitata) as explants, regenerated plants with kanamycin resistance were obtained mediated by Agrobacterium tumefaciens (strain LBA4404). The transformed plants with the CryIA(c) (Bt) gene were confirmed by Southern blotting analysis, indicating the integration of the transgene into the cabbage genome. The majority of the transgenic plants had only a single copy of the inserted CryIA(c) gene. Leaf section bioassays showed that resistance against larvae of diamondback moth in CryIA(c) transgenic cabbage was significantly enhanced. The inheritance patterns of the transgene in T1 offspring of transgenic cabbage were investigated using polymerase chain reaction (PCR) analysis and a kanamycin resistance test on the leaves of young seedlings. The results showed that dominant gene loci, CryIA(c) or neomycin phosphotransferase gene (NPTII), followed Mendelian inheritance, with a ratio of 3:1 segregation in T1 populations.
