Abstract
On the basis of the similarity values in the electrophoretic relative mobility of seven enzymes, the strains of the genera Rhodosporidium, Cystofilobasidium, and Rhodotorula were analyzed numerically. The strains with the ubiquinone Q-10 system were divided into six major clusters, the strains with the Q-9 system into two major clusters, and the strains with the Q-8 system into two major clusters. The strains of Rhodotorula glutinis were clearly separated into four clusters. In the species of the genera Rhodosporidium and Cystofilobasidium, compatible mating-type strains were included in the same clusters. Furthermore, compatible mating-type strains of Rhodosporidium toruloides, Rhodosporidium diobovatum, and Rhodosporidium infirmominiatum, were divided into two subclusters, within the respective species.
