The genome of F. graminearum is made up of an assembly of plasmid, fosmid, and bacterial artificail chromosome, totaling 36.1 Mb and displaying high sequence quality and continuity.

Genome structure
The genome of F. graminearum is made up of an assembly of plasmid, fosmid, and bacterial artificail chromosome, totaling 36.1 Mb and displaying high sequence quality and continuity. It is predicted that the genome contains a set of 11,640 genes and four chromosomes. Certain regions of the chromosomes have been found to have high levels of polymorphisms and high levels of recomination between strains of the species. An interesting feature of this observation is that genes that are specifically expressed during plant infection are all over-represented in high density single nucleotide polymorphic regions. The genome appears to have very few repetative sequences with fewer high-identity duplicates. It has been speculated that this is the result of repeat-induced point mutations.
Cell structure and metabolism
Interesting features of cell structure; how it gains energy; what important molecules it produces.
Ecology
Habitat; symbiosis; contributions to the environment.
Pathology
How does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
Current Research
Enter summarries of the most rescent research here--at least three required
