Abstract
Suspension culture cells of barley (Hordeum vulgare L. cv. Klages) were collectec on filters and bombarded with gold particles carrying the Basta® resistance (bar) gene, or both bar and the β-glucuronidase (uidA) genes in a Biolistic® Particle Accelerator. Filters carrying the bombarded tissues were selected on basal medium with increasing concentrations (maximum of 200 mg I-1) of phosphinothricin. Surviving calli were assayed for the presence of phosphinothricin acetyltransferase activity. All positive calli were shown to have the bar gene integrated into their genome. Nine independent stable transformation events have been analyzed with substantial variation in the integration pattern and transgene copy number. Some albino plantlets were produced, but no mature plants were obtained.
