Outline of Final Research Achievements

The aim of this study is understanding the evolutionary origin of insect wing. We studied orthologs of genes that are important for Drosophila wing development in basally branching insects, the two-spotted cricket and the firebrat. Our results suggest that insect wing originates from tergal margin of a wingless ancestor. Through this study, we succeeded the first targeted gene knockout in the firebrat.
