Aspergillus nidulans

Description and significance

A. nidulans is a form of filamentous fungi that has proved to serve as a valuable model organism in the realm of eukaryotic cell biology.  Due to its capabilty to generate sexual spores via meiosis, researchers are capable of generating variable strains of the species.  For the last 50 years, A. nidulans has been used to study a wide array of processes and topics such as cell cycles, DNA repair, nucleokinesis, pathogenesis, mutation, and evolutionary processes. As a model organism, species' diversified genome (unlike its relatives) allows for a more developed understanding of other species in the Aspergillus genus.

Genome structure

Considering that A. nidulans is sexually reproductive, it contains a well-developed genetics system. Its genome is composed of 30 million base pairs in size with around 9,500 protein-coding genes on eight different chromosomes [1].
