    基于线粒体COI序列对云南地区柚喀木虱单倍型的鉴定

    Identification of haplotypes of Cacopsylla citrisuga from Yunnan Province based on mitochondria COI sequence

      摘要
    • 摘要:
      目的 研究采自云南的柚喀木虱Cacopsylla citrisuga Yang & Li种群的遗传多样性.
      方法 利用线粒体细胞色素C氧化酶亚基Ⅰ基因(COI)条形码片段对采自云南瑞丽和石屏的柚喀木虱样本进行描述，并进行遗传距离和系统发育分析.
      结果和结论 经鉴定共得到2种单倍型C1和C2，瑞丽种群的单倍型均为C1，而石屏的种群分化出了2种单倍型C1和C2.分析表明，柚喀木虱的最大序列分歧度特别低，仅为0.16%.此COI片段能很好地区分柚喀木虱与同属的其他几种木虱.

       

      Abstract:
      Objective To characterize genetic diversity levels of Cacopsylla citrisuga Yang & Li collected from two regions of Yunnan Province.
      Method The samples of C. citrisuga from Ruili city and Shiping county were identified by the gene barcoding of the mitochondrial cytochrome C oxidase subunit Ⅰ (COI). The phylogenetic tree and genetic distance were obtained.
      Result and conclusion Two haplotypes of C. citrisuga, C1 and C2 were identified. C1 was the only haplotype of the populations from Ruili city, while C1 and C2 both existed in the population from Shiping county. Unlike other previous studies of insects, the COI-based genetic diversity of C. citrisuga was extremely low, with the maximum sequence divergence being only 0.16%. The COI fragment can be used to distinguish C. citrisuga from the other four Cacopsylla species successfully.
