Abstract Transgenic Japanese lawngrass (Zoysia japonica Steud.) plants were generated by means of polyethylene glycol (PEG)-mediated direct gene transfer into protoplasts. The plasmid pBC1 was used to deliver the hygromycin phosphotransferase (hph) and β-glucuronidase (gus) genes into protoplasts. Selection with a high concentration (400 mg/l) of hygromycin yielded a number of resistant calli and about 400 plants were generated. Polymerase chain reaction (PCR) and Southern hybridization analyses revealed that all of then plants tested contained introduced genes. The gus gene regulated by the maize alcohol dehydrogenase-1 (Adh 1) promoter was expressed in the leaves and roots of transgenic Japanese lawngrass plants.
