Abstract

Drosophila prolongata exhibits extreme sexual dimorphism in terms of different morphological, behavioral, and life-history traits. To clarify the biological function of genes underpinning such unique traits, the strains for phiC31 integrase-mediated transgenesis of D. prolongata have been established. This study aimed to make further use of the strains by identifying the chromosomal location of attP landing sites with reference to the D. melanogaster genome in silico. The results showed that some inverted orders of genes may have occurred between D. prolongata and D. melanogaster. Such chromosomal rearrangements might be important evolutionary driving forces for the emergence of unique traits in D. prolongata.
