FIG. 1.

(A) mtDNA patterns from sparkling-wine yeasts. The column labeled λ shows phage 1 DNA cut with PstI, which was used as a size marker (sizes are shown on the left, expressed in base pairs). Note the strong similarity between patterns CF2 and CF3. (B) Karyotype profiles of strains CF2-2 (a CF2 strain) and CF3-5 (a CF3 strain) and the laboratory strain W303a. Roman numerals shown on the left indicate the ascription of each band to the different yeast chromosomes (as described in reference 19). Z1 through Z6 shown on the right indicate the different chromosome regions into which the karyotypes of the sparkling-wine yeasts were subdivided as described previously (16).
