This study was conducted to obtain the transformed birdsfoot trefoil (Lotus corniculatus L.) plants with BcHSP17.6 gene using Agrobacterium turnefaciens LBA4404 and we confirmed transformed gene from the regenerated birdsfoot trefoil plants. The expression vector, pBKH4 vector, harboring BcHSP17.6 gene was used for production of transgenic birdsfoot trefoil plants. The callus of birdsfoot trefoil was cocultivated with Agrobacteriurn turnefaciens and transformed calli were selected on kanamycin-containing SH-kc medium to regenerate into plants. The transformed birdsfoot trefoil plants were produced 4 momths after cultivation on BOi2Y medium. The transgenic birdsfoot trefoil plants were analyzed by isolation of genomic DNA and genomic Southern hybridization using a -32P labelled BcHSPl7.6 fragments.
