Description and Significance
Describe the appearance, habitat, etc. of the organism, and why you think it is important.
Genome Structure
The genome size of Odinarchaeota is 1.4 Mb. Odinarchaeota only has 1 chromosome, and it is circular. There is very little research done about Asgard archaea, and even less research done on Odinarchaeota. 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.
Ecology and Pathogenesis
Odinarchaeota are found all over the world, in different geographical regions and habitats. Odinarchaeota is typically found in sediments with high salinity and at great depths. But some Odinarchaeota can be found on the body of some animals, in freshwater, on the sea surface, and even in certain plants. Odinarchaeota is very significant because researchers believe a merger of Asgard archaea, and an aerobic bacterium created the eukaryotes with aerobic mitochondria. It is also believed that a second merger is what created the chloroplasts in plant cells. Using metagenomics researchers have found that several viruses are associated with Asgard archaea. Viruses associated with Asgard archaea were assigned to specific hosts using CRISPR sequencing, this is how Odinarchaeia was discovered.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
