测定了豌豆蚜的线粒体全基因组序列，并与其他蚜虫的基因组序列进行了比较。共和党psidii有丝分裂基因组全长16，202 bp，A + T含量为85.4%，包括37个基因、一个控制区和一个位于trnE和trnF之间的特殊重复区。G. psidii是第一个具有这种重复区域的代表，来自Greenideinae亚科。这些重复基序存在于蚜亚科，Eriosomatinae和Greenideinae中，具有物种特异性，不同物种的核苷酸组成，长度和拷贝数不同。所有报道的完整蚜虫有丝分裂基因组在整个基因组中是A-和C-偏斜的，并且在多数和少数链之间显示C和G的相反偏斜。非同义替换率与同义替换率的比值表明，蚜虫有丝分裂基因组的进化是由纯化选择主导的。基于全基因组序列，研究了所有具有完整有丝分裂基因组的蚜虫种间的系统发育关系。G. psidii与Cervaphis quercus聚类，确认其隶属于Greenideinae亚科。(C)2018作者由爱思唯尔公司出版
The complete mitochondrial genome of Greenidea psidii was sequenced and compared with the genomes of other aphid species. The G. psidii mitogenome is 16,202 bp long with an A + T content of 85.4%, comprising 37 genes arranged in the same order as the inferred insect ancestral arrangement, a control region and a special repeat region between trnE and trnF. G. psidii is the first representative possessing such a repeat region from the subfamily Greenideinae. These repeat motifs found in Aphidinae, Eriosomatinae and Greenideinae are species-specific, differing in nucleotide composition, length and copy number across different species. All reported complete aphid mitogenomes are A- and C-skewed in the whole genomes and show opposite skewness for C and G between the majority and minority strands. The ratios of nonsynonymous to synonymous substitution rates indicated that the evolution of the aphid mitogenomes has been dominated by purifying selection. Based on whole mitogenome sequences, the phylogenetic relationships among all aphid species with complete mitogenomes were investigated. G. psidii was robustly clustered with Cervaphis quercus, confirming its affiliation with the subfamily Greenideinae. (C) 2018 The Authors. Published by Elsevier B.V.
