The aim of this study was to determine the species boundaries within the Aspergillus viridinutans species complex. The species belonging to this complex are predominantly soil- inhabiting organisms that are increasingly reported as opportunistic human and animal pathogens. A total number of 98 isolates from various substrates and countries was subjected to morphological, physiological and molecular analysis (calmodulin, β-tubulin, actin and RNA polymerase II subunit 2 gene) and mating experiments were provided on different media and temperatures. Some other heterothallic species from section Fumigati with unknown sexual state were analysed using similar method as well. Key words: Aspergillus viridinutans, Aspergillus turcosus, phylogenetic analysis, mating- type genes, anamorph, teleomorph, mating experiments, MAT1-1, MAT1-2 |
