Comparative analysis of genetic incompatibility in Aspergillus niger and Podospora anserina
Reproduction is of crucial importance for living organisms, from bacteria to humans. Except for mammals and birds, both sexual and asexual reproduction is known almost at every level of thephylogenetictree. A special case of asexual reproduction in filamentous fungi is the so calledparasexualcycle, whenhyphaeof different individuals fuse and the genetic material of different origin can be mixed. The black mouldAspergillusniger is a versatile organism used in industry and sometimes found as opportunistic pathogen. This is an asexual species, and most of the natural isolates are unable to undergo theparasexualcycle, in other words strains are (vegetatively) incompatible. Unlike the A.niger thePodosporaanserina is a strictly sexual species and used as a model organism for studying features ofparasexualcycle. In this study the genetic background of vegetative incompatibility and remnants of presumed ancient sexual stage of A.niger and features of vegetative incompatibility in P.anserina were investigated and compared.
