Southern hybridization of high-molecular-weight DNA fragments of the minichromosome containing Beta vulgaris line PRO1. DNA was digested with HindIII (1), HaeIII (2), HpaII (3), XbaI (4), and restriction fragments were separated by pulsed-field gel electrophoresis. After transfer onto nylon membranes, filters were hybridized with radioactively labeled pTS4.1 (A) and pTS5 (B).
