Different phenotypical or molecular techniques can be used to describe and classify microorganisms for taxonomic, phylogenetic or genetic purposes. In yeast taxonomy the official hierarchic classification, based on morphological and physiological characters, is used together with more convenient molecular techniques such as the DNA sequencing. The question on whether these procedures produce coherent classifications is critical both to interpret taxonomic data consistently and to outline species correctly. In this paper, a set of type strains from the major genera of the budding hemiascomycetes yeast is examined with a series of physiological and molecular techniques, widely employed in taxonomy, in order to compare the among-strains correlations obtained with different methods. Results showed that the level of correlation among different techniques is relatively low, showing that different classifications and species organization could be obtained with diverse approaches. This is particularly interesting, considering that the official description of the yeast species is based on characters different from those becoming increasingly popular in the routine identification. |
