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 .

phiC31整合酶介导的果蝇（双翅目：果蝇科）转基因菌株中attP着陆位点的染色体定位

延长果蝇在不同的形态、行为和生活史特征方面表现出极端的两性异形。为了阐明支持这些独特性状的基因的生物学功能，已经建立了 phiC31 整合酶介导的 D.longata 转基因菌株。本研究旨在通过参考计算机中黑腹果蝇基因组鉴定 attP 着陆位点的染色体位置来进一步利用这些菌株。结果表明，D.longata 和D. melanogaster 之间可能发生了一些基因倒序。这种染色体重排可能是在 D.longata 中出现独特性状的重要进化驱动力。
