项目摘要
In this study, we have focused on a ground beetle group Ohomopterus in Japan, which consists of 15 species with marked interspecific diversity of genital morphology. We analyzed the genetic basis of interspecific difference in genital morphology between two Ohomopterus ground beetles using a quantitative genetic and QTL mapping approach. In the quantitative genetic analysis, it was inferred that relatively small number of genes produced the large difference in genitalia between 0. iwawakianus and 0. maiyasanus. We also conducted a QTL mapping with F2 hybrids of these species using AFLP and microsatellite markers. We analyzed evolutionary trend of genital morphology in relation to other reproductive traits using a comparative method, and found that exaggeration of genital morphology occurred in association with spermatophore size and copulation time. In addition, we analyzed shape of sperm and sperm-bundles which can be selected for improvement of sperm-competition ability. We found a d … More imorphism of sperm-bundles, i.e. long and short types, in most species and revealed that long sperm bundles have been evolved in association with other reproductive traits including genital parts. The evolution of genital morphology is considered to have occurred within populations through sexual selection and could have contributed to mechanical reproductive isolation which promotes speciation. A similar effect is expected for differentiation in body size. Using interspecific mitochondrial gene flow as an index of intrgressive hybridization, we revealed that differences in genital and body sizes had effect to prevent introgressive hybridization. Besides the above studies, we also studied the effect of cuticular hydrocarbon (CHC) on mate recognition and variation in CHC among species to explore the potential role of CHC as sexual pheromones to enable coexistence of closely related species. In addition, the pattern and strength of pre-and post-mating reproductive isolation between various pairs of Ohomopterus species. Less
在本研究中,我们集中研究了日本的地面甲虫群Ohomopterus,该群由15种组成,生殖形态具有明显的种间多样性。采用定量遗传和QTL定位方法,分析了两种异翅目地甲虫生殖形态种间差异的遗传基础。在定量遗传分析中推断,相对较少的基因在0和0之间产生了较大的生殖器差异。Iwawakianus和0。maiyasanus。我们还利用AFLP和微卫星标记对这些物种的F2杂交种进行了QTL定位。采用比较方法分析了生殖器官形态与其他生殖性状的进化趋势,发现生殖器官形态的夸张与精包大小和交配时间有关。此外,我们还分析了精子形态和精束的选择,以提高精子竞争能力。我们在大多数物种中发现了更多的精子束的同形性,即长精子束和短精子束,并揭示了长精子束的进化与其他生殖特征包括生殖器部位有关。生殖形态的进化被认为是通过性选择在种群内发生的,并可能促成了促进物种形成的机械生殖隔离。体型的分化也有类似的效果。利用种间线粒体基因流作为入侵杂交的指标,我们发现生殖器和身体大小的差异对阻止入侵杂交有影响。除上述研究外,我们还研究了角质层碳氢化合物(CHC)对配偶识别的影响以及物种间CHC的变化,以探索CHC作为性信息素的潜在作用,使近缘物种能够共存。此外,还比较了不同对同翅目昆虫交配前后的生殖隔离模式和强度。少
