Abstract
Abstract: Aspergillus terreus has a worldwide distribution in soils, constitutes the third most important cause of invasive aspergillosis in humans and is classically regarded as a strictly asexual species. A. terreus strains were characterized by sequencing of ITS, β-tubulin and calmodulin. Opposite mating types identified by amplifying and sequencing MAT1-1 and MAT1-2 genes were crossed and opposite mating types were challenged to undergo sexual reproduction. Heterothalically produced ascomata of one MAT1-2 strain crossed with four MAT1-1 strains, were observed in mixed cereal agar after 3 weeks at 37 ?C. Endoascomatous cleistothesia were formed, consisting of yellow, elongate, cylindrical cells. Asci were mostly eight-spored and ascospores were hyaline to pale yellow, one-celled, smooth-walled and sphaerical to broadly ovoid, with an equatorial protuberance. It is the first time that this common, nonetheless fastidious, pattern of sexuality is observed in A. terreus and instigates further research on the sexual behaviour of other members in section Terrei.
