Plant regeneration from protoplasts of Panax ginseng (C.A. Meyer) through somatic embryogenesis
1Department of Physiological Botany, University of Uppsala, Box 540, S-751 21, Uppsala, Sweden.
Abstract:
Protoplasts of Panax ginseng were isolated from embryos obtained from the 4-year old embryogenic cell line KCTC PCL 49031 which was derived from a zygotic embryo. High protoplast yields of 22-25 × 10(6) protoplast / g tissue were obtained following 5-6 h digestion with 2% Cellulysin, 1% Pectinase and 1% Macerasae in half strength Murashige and Skoog's medium containing 12% mannitol. A plating density of 1×10(5) protoplasts /ml was found optimal for protoplast culture. An initial division frequency of 10% was obtained in an agarosegelled defined medium. Myo-inositol (6%) was found to be the most suitable osmoticum. Somatic embryos were formed from protoplast derived embryogenic callus, which regenerated into plantlets.
