Abstract

The mitochondrial genome (mitogenome) of Gallinago gallinago gallinago Linnaeus, 1758 was determined by the high-throughput data. The assembled mitogenome was 16,919 bp in length, with a 58.7% A + T content and GC skew of −0.3850. Among 13 PCGs, an unusual start codon (GTG) was identified for the COX1 gene, and incomplete stop codons (T-) were found in the COX3, ND2 and ND4 genes. The function of a cytosine insertion at site 174 in the ND3 gene and its phylogenetic significance are worthy of further scrutiny. In the control region (CR), thirteen 15-bp simple sequence repeats were found in G. g. gallinago. Phylogenetic analysis indicated that Gallinago was clustered at the basal position of the Scolopax clade and that the monophyly of Gallinago was also recovered. The mitogenome data of G. g. gallinago provides useful resources for further studying the evolution of Scolopacidae.

摘要

Gallinago gallinago gallinago Linnaeus, 1758的线粒体基因组（mitogenome）由高通量数据确定。组装的有丝分裂基因组长度为 16,919 bp，A + T 含量为 58.7%，GC 偏斜为 -0.3850。在 13 个 PCG 中，发现了COX1基因的异常起始密码子 (GTG) ，并且在COX3、ND2和ND4基因中发现了不完整的终止密码子 (T-) 。ND3基因第174 位胞嘧啶插入的功能及其系统发育意义值得进一步研究。在控制区 ( CR ) 中，在G. g.中发现了 13 个 15-bp 简单重复序列。加利纳戈. 系统发育分析表明，Gallinago聚集在Scolopax进化枝的基部位置，并且也恢复了Gallinago的单系。G. g.的有丝分裂基因组数据 gallinago为进一步研究 Scolopacidae 的进化提供了有用的资源。
