Aspergillus oryzae
Genome
The entire genome of A. oryzae contains eight chromosomes and is 37.6Mb in size.[1] In comparison with the two other Aperigilli, A. oryzae is 25-30 percent larger in its genome, and has 2000-3000 more genes than the other two species A. nidulans and A. fumigates [2]. A. oryzae is linear. Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?
Cell Structure, Metabolism and Life Cycle
Interesting features of cell structure; how it gains energy; what important molecules it produces. When A. Oryzae comes in contact with energy sources, it secretes enzymes capable of converting complex organic molecules to simpler ones Many of the extra genes present in A. oryzae are predicted to be involved in secondary metabolism. It is asexual
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
The habitat that the A. oryzae live in are oxygen rich environments. It is highly aerobic and grow as molds on the surface of a substrate. They are contaminants of starchy foods such as bread and potatoes and may grow on plants and or trees as well. Members of its genus can also be used for medications that treat diseases.
