Abstract:

Objective To evaluate the feasibility of DNA barcoding applied to the identification of flies in Fujian province, China, and to set up the nucleic acid sequence database for flies in Fujian. Methods Sixty-four fly specimens belonging to 19 species, 13 genera, and 4 families were collected from Fujian. Genomic DNA was extracted from the flies. Mitochondrial COⅠ gene was amplified by consensus primer PCR and sequenced. Sequence alignment and evolutionary divergence were performed, and a neighbor-joining phylogenetic tree was constructed based on these sequences. Results Intraspecific divergence ranged between 0-3.32%; interspecific divergence ranged between 5.26%-18.30%, except for Lucilia cuprina and Lucilia sericata, which had only 0.69% divergence from each other. The result of phylogenetic tree showed that sequences from the same species gathered closely with each other. The reliability of Bootstrap test was all above 96%. Conclusion DNA barcoding can be effectively used to identify some flies in Fujian province. It can be used as an efficient method supplementary to morphological identification.

摘要:

目的 探讨DNA条形码技术应用于福建省蝇类鉴定的可行性,并初步建立福建省蝇类的基因数据库。方法 采集自福建省部分地区的4科13属19种64个蝇类新鲜标本,提取基因组DNA进行PCR扩增,序列测序,并进行同源性对比、进化距离分析,构建系统进化树。结果 基因序列分析结果显示,上述蝇类mtDNA上细胞色素C氧化酶亚基Ⅰ基因序列的种内进化分歧均数在0~3.32%之间;除铜绿蝇与丝光绿蝇进化分歧均数为0.69%外,其余种间进化分歧均数在5.26%~18.30%之间;系统进化树分析显示,相同种能够很好聚集在一起,Bootstrap 检验可信度均达96%以上。结论 DNA条形码技术可用于福建省一些常见蝇类的鉴定,作为形态学鉴定的补充手段。
