Abstract
Protoplasts were isolated from primary calli of barley (Hordeum vulgare L.), and an antibiotic (G418) resistance gene was introduced into these protoplasts using a polyethylene glycol (PEG) DNA uptake method. Sixty-four G418 resistant calli were obtained in nine experiments, and two plants were regenerated from these calli. NPTII ELISA and Southern analysis indicated that the G418 resistance gene was introduced and expressed in two T0 plants. These plants set seed and the introduced gene was transmitted to T1 plants. These results suggest that our transformation system using primary callus-derived protoplasts is a useful method for the generation of transgenic barley.
