完整的线粒体基因组序列对于更好地理解基因组水平的特征和近缘物种之间的系统发育关系具有重要意义。本研究测定和分析了荷桃黑滨藜线粒体基因组全长15,379bp(GenBank：KT581634)，其中包括13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和一个非编码区(控制区)。除COX/基因由CGA密码子启动外，所有编码蛋白质的基因均以ATN密码子开头，以终止密码子T、TA或TM结尾。除trnS1外，所有tRNA都具有典型的三叶草二级结构，其中Dhu臂不能形成稳定的茎环结构。RrnL和RRN的二级结构分别由49个螺旋和33个螺旋组成。对相关物种线粒体基因组全序列和13个线粒体蛋白编码基因的氨基酸序列进行的系统发育分析支持河套潜蝇与蜂总科的亲缘关系比与真蚁总科的亲缘关系更近的观点。这一结果与以前基于形态的分类是一致的。(C)2016爱思唯尔B.V.保留所有权利。
Complete mitochondrial genome sequences are of great importance for better understanding the genome-level characteristics and phylogenetic relationships among related species. In this study, the complete mitochondrial genome of Atrijuglans hetaohei Yang is sequenced and analyzed, which is 15,379 bp in length (GenBank: KT581634) and contains a typical set of 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a non coding region (control region). Except for cox/gene that is initiated by CGA codon, all protein-coding genes start with ATN codons and end with the stop codon T, TA or TM. All tRNAs have a typical clover-leaf secondary structure, except for trnS1, of which the DHU arm could not form a stable stem-loop structure. The secondary structure of rrnL and rrnS consists of 49 helices and 33 helices, respectively. Phylogenetic analyses of the complete mitochondrial genome sequences and of the amino acid sequences for 13 mitochondrial protein-coding genes among related species support the view that A. hetaohei is more closely related to the Gelechioidea than Yponomeutoidea. This result is consistent with a previous classification based on morphology. (c) 2016 Elsevier B.V. All rights reserved.
