Abstract

Analyses of the sequences of the small-subunit (18S) rRNA gene and two internal transcribed spacers (ITSs), ITS1 and ITS2, revealed that members of the yeast genera and are phylogenetically intermixed. Despite some minor differences in 18S rRNA-, ITS1-, and ITS2-derived trees, in general the patterns of the relationships inferred from the three chronometers were in good agreement. The ITS sequences of and species exhibited far greater interspecies differences than the 18S rRNA sequences and were better than 18S rRNA sequences for measuring close genealogical relationships. Despite the existence of interstrain ITS sequence variation in some species, it is possible to identify conserved regions in both ITSs that are useful in species differentiation.
