This study was conducted to obtain basic information about the transformation of ginseng tissue, identification of opine compound and protein, and saponin production from ginseng callus transformed with Ti-plasmic of AW$.$obacterium tumefaiens C58. Ginseng crown gall callus induced by pTiC58 could be continuously cultured on the Phytohormone-free medium. The transformation was reconfirmed by the detection and identification of opine compound, from the gall callus. The transformed ginseng callus contained higher amounts of protein than normal callus and the protein pattern of transformed callus was quite different from that of normal callus. The xylose which is not detected in the normal callus and ginseng root was identified in gall callus. The saponin contents of gall callus of ginseng were three times higher than that of normal callus, and ginsenoside composition of the transformed callus was similar to that of the cultivated ginseng root, but quite different from that of normal callus.
