Karyotyping and chromosomal localization of BIO1 in evolved biotin-prototrophic yeast strains. (A) Pulsed-field gel electrophoresis (PFGE) of the chromosomes of evolved biotin-prototrophic strains IMS0478, IMS0480, IMS0481, and IMS0496 and the parent strain, S. cerevisiae CEN.PK113-7D. Chromosome numbers and sizes (kilobases) were obtained using S. cerevisiae S288C as a reference strain. (B) Southern blot of the PFGE gel. Hybridization with BIO1 probe revealed copies of BIO1 on multiple chromosomes in the evolved strains.
