Abstract:

The family of Trichocomaceae harbors various economically important genera, such as Aspergillus, Penicillium and
Paecilomyces. The importance of these genera is illustrated by the high number of undertaken full genome
sequencing projects. Recently, new insights in the taxonomy of Aspergillus and Penicillium have led to numerous
new species and name changes of existing species. In this study, the phylogeny of the full genome sequenced
strains is investigated using the protein coding genes RPB1, RPB2, Cct8 and Tsr1. Furthermore, the impact of
recent developments in the taxonomy of these strains is addressed.
Phylogenetic analysis shows a close relationship between the full genome sequenced strains (or representatives of
the same species) of Aspergillus, Penicillium sensu stricto, Monascus and Xeromyces. Talaromyces stipitatus and
Penicillium marneffei appear to be distantly related to Aspergillus and Penicillium sensu stricto. As a consequence,
Talaromyces is re8208;defined and the combination Talaromyces marneffei (= P. marneffei) is proposed, leaving P.
chrysogenum as the sole full genome sequenced species in Penicillium. Furthermore, Talaromyces emersonii is
transferred to the new genus Rasamsonia and Talaromyces thermophilus will be transferred to Thermomyces. The
new insights in the relationship among Aspergillus, Penicillium and related genera will help to interpret the results
generated with comparative genomics studies or other studies dealing with evolution of e.g. mating type loci,
virulence genes and secondary metabolite biosynthetic gene clusters.
