以mtDNA的COⅠ基因的部分序列作为分子标记,研究了来自安哥拉、黎巴嫩、刚果共和国、尼日利亚、贝宁、多哥、加纳、科特迪瓦、南非、埃及、法国、约旦、秘鲁、智利、美国佛罗里达和美国夏威夷等16个国家和地区共75个个体的地中海实蝇Ceratitis capitata地理种群序列特征和单倍型特征,并分析了各种群间的遗传分化水平和进化关系,结果表明,在供试的样品中发现单倍型的数目是29,其中有5种为共享倍型。地中海实蝇各地理种群的遗传多态性水平差异较大,总体遗传距离D等于0.007。非洲南撒哈拉区(安哥拉、刚果、尼日利亚、贝宁、多哥、加纳、科特迪瓦)的种群的单倍型数、单倍型百分比和群内遗传距离等遗传多态性参数值都高于其它供试地区,多样性明显较其他地区丰富。
The partial sequences of mtDNA COⅠ gene were used as molecular markers to study the genetic diversity of mtDNA genes from Angola, Lebanon, the Republic of the Congo, Nigeria, Benin, Togo, Ghana, Cote d’Ivoire, South Africa, Egypt, France, Jordan, Peru, Chile, Hawaii and other 16 countries and regions in a total of 75 individuals of Mediterranean fruit fly Ceratitis capitata geographical population characteristics and haplotype characteristics and analysis of the genetic differentiation between populations and evolutionary relationships results show that the test sample The number of haplotypes found was 29, of which 5 were shared fold. The genetic diversity of the geographical populations of the Mediterranean fruit flies varied greatly, with an overall genetic distance D equal to 0.007. Haplotypes, haplotypes and intra-population genetic distances among populations in sub-Saharan Africa (Angola, Congo, Nigeria, Benin, Togo, Ghana and Cote d’Ivoire) In the pilot areas, the diversity is obviously more abundant than in other areas.
