SIGNIFICANCE OF DNA BASE COMPOSITION IN THE CLASSIFICATION OF YEAST GENUS PICHIA

[摘要] The DNA base composition (GC content) of 53 cultures of Pichia and supposed related yeasts, which represented 35 species and a variety, was investigated. The GC content of Pichia ranged from 28.3 to 50.2%, and intrageneric variation was about 22%. Any prominent subgroups could not be detected within the genus and this genus was supposed to be very heterogeneous from the taxonomic points of view.
