Characterization and population analysis of the mating-type genes in Aspergillus flavus and Aspergillus parasiticus

We characterize the mating-type genes in Aspergillus flavus , Aspergillus parasiticus and Petromyces alliaceus. A single MAT1-1 or MAT1-2 gene was detected in the genomes of A. flavus and A. parasiticus, which is consistent with a potential heterothallic organization of MAT genes in these species. I...

Zusammenfassung:We characterize the mating-type genes in Aspergillus flavus , Aspergillus parasiticus and Petromyces alliaceus. A single MAT1-1 or MAT1-2 gene was detected in the genomes of A. flavus and A. parasiticus, which is consistent with a potential heterothallic organization of MAT genes in these species. In contrast, the only known, functionally homothallic species in Aspergillus section Flavi, P. alliaceus, has tightly linked (
