title: Improved procedure for nucleus extraction for DNA measurements by flow cytometry of red beet (Beta vulgaris L.) hairy roots.
abstract: Three often cited systems for the extraction of plant nuclei for flow cytometric measurement (CyStain PI, Partec GmbH, Münster, Germany, the method of Arumuganathan and Earle, and LB01 buffer) failed, when applied to the hairy roots of red beet (Beta vulgaris). By combining these systems and introducing a centrifugation step, the extraction, staining, and analysis of nuclei from this tissue were performed successfully.
