Outline of Final Research Achievements

Acquisition of genetic material through lateral gene transfer is important for the genome evolution of organisms. Our aim for this project is to reveal the evolutionary history of transferred genes and their functions in the recipients. Using assembled genome data of various insects, we tried to find transferred genes, their potential donars and their evolutionary patterns. Initially, we used genomes from 9 insects, which harbor obligate symbionts or are closely related with species establishing a symbiotic relationship with bacteria. All of the genomes investigated contained the candidates of bacterial-derived sequences.
