Abstract
Protoplasts isolated from a barley cell suspension (cv Dissa) were transformed with plasmid DNA containing the neomycinphosphotransferase II (NPT) and β-glucuronidase (GUS) genes, using polyethyleneglycol (PEG) to induce DNA uptake. Transformed microcalli were selected in media containing G418 sulphate. NPT activity was detected in all antibiotic-resistant cell lines, but not all NPT-positive cell lines had GUS activity. Southern analysis confirmed the presence of sequences homologous to the APT and GUS genes in DNA of G418-resistant callus.Entities:
