Blattabacterium Genome: Structure, Function, And Evolution, Austin Alleman

Biology Theses

Blattabacterium, an obligate bacterial endosymbiont, functions as a mechanism of nitrogen recycling and nutrient synthesis within the Order Blattaria (cockroaches). Through genome annotation and the application of bioinformatics, the function of Blattabacterium within the cockroach Nauphoeta cinerea was described. Results of analyses indicate that the Blattabacterium genome, comprised of ~620,000 base pairs and ~620 individual genes, is drastically reduced when compared Flavobacterium, Blattabacterium’s closest free-living relative. However, the Blattabacterium genome retained functionality vital to host survival and fecundity and functions as a source of additional nutrient biosynthesis within its host. Like other intracellular endosymbionts, the Blattabacterium genome has a G+C …
