Abstract
Phylogenetic relationships of species assigned to the genus Metschnikowia were estimated from the extents of divergence among partial sequences of rRNA. The data suggest that the aquatic species (Metschnikowia australis, Metschnikowia bicuspidata, Metschnikowia krissii, and Metschnikowia zobellii) and the terrestrial species (Metschnikowia hawaiiensis, Metschnikowia lunata, Metschnikowia pulcherrima, and Metschnikowia reukaufii) form two groups within the genus. M. lunata and M. hawaiiensis are well separated from other members of the genus, and M. hawaiiensis may be sufficiently divergent that it could be placed in a new genus. Species of the genus Metschnikowia are unique compared with other ascomycetous yeasts because they have a deletion in the large-subunit rRNA sequence that includes nucleotides 434 to 483.Keywords
