The full length of the maize γ-zein gene amplified by PCR from PROK.TG1LK plasmid was ligated into the intermediate vector pMD18-T, to obtain the recombinant plasmid named pMD18-γ-zein. After the recombinant plasmid and the improved pCAMBIAI1302,respectively were digested by Nco I and Bgl II restriction endonucleases, the plant expression vector pCB-GFP-γ-zein with the gene of green fluorescent protein (GFP) driven by 35S was built following the procedures of recovery, ligation, transformation and identification. The fusion of GFP-γ-zein gene was integrated into the onion epidermal cells by using the Biolistic approach; the fusion gene was expressed in onion epidermal cell wall, nucleus and cytoplasm confirmed by confocal microscopy.
