线粒体（mt）基因序列已被广泛用于推断动物的遗传。mt基因在有丝分裂基因组中的相对顺序也可以作为进化的有用标记，但是mt基因重排的倾向在不同的分类群中差异很大。阿卡里的蜱和螨类则与这一趋势相反，因为有些家族保留了祖先的节肢动物基因顺序，而另一些家族则表现出高度分化的基因顺序。植绥螨科中的螨，其中许多是有效的生物控制剂，显示出一些最不同的基因顺序。然而，在这个家庭的多样性的有丝分裂基因组顺序是鲜为人知的。因此，我们测序了三个mt基因组的植绥螨从两个最speciose属：斯氏钝绥螨（Athias-Henriot），Amblyseius tsugawai（Ehara）和Neoseiulus womersleyi（Schicha）。我们发现不同的mt GC偏斜和核苷酸组成，特别是N。沃默斯利和两种钝绥螨植绥螨科（Phytoseiidae）内的每个物种（包括三个先前可用的序列）都呈现出独特的基因顺序。与祖先节肢动物目相比，植绥螨有丝分裂基因组显示出一些最高数量的断裂点（高达33个），以及该家族内的高数量的断裂点（14-30）。这表明家族中存在大规模的、持续的有丝分裂基因组重排的历史。mt序列的系统发育分析证实基因重排的程度遵循系统发育相关性。我们讨论了植绥螨内MT基因重排程度高的可能原因，以及MT和核基因组中的选择与该家族中许多不同摄食策略的独立进化有关。最后，我们建议N。womersleyi应该被用来代替同义词Amblyseius pseudolongispinosus。
Mitochondrial (mt) gene sequences have been widely used to infer phylogeny in animals. The relative order of mt genes in the mitogenome can also be a useful marker for evolution, but the propensity of mt gene rearrangements vary tremendously among taxa. Ticks and mites in Acari exemplify this trend as some families retain the ancestral arthropod gene order, while others show highly divergent gene orders. Mites in Phytoseiidae, many of which are effective biological control agents, show some of the most divergent gene orders. However, the diversity of mitogenome order within this family is little known. We thus sequenced three mt genomes of phytoseiid mites from two of the most speciose genera: Amblyseius swirskii (Athias-Henriot), Amblyseius tsugawai (Ehara) and Neoseiulus womersleyi (Schicha). We find differences in mt GC skew and nucleotide composition, especially between N. womersleyi and the two Amblyseius species. Each species within Phytoseiidae (including three previously available sequences) present a unique gene order. Phytoseiid mitogenomes show some of the highest numbers of breakpoints when compared to the ancestral arthropod order (up to 33), as well as high numbers of breakpoints within the family (14-30). This suggests a history of massive, ongoing mitogenome rearrangements in the family. Phylogenetic analyses of mt sequences confirm that the degree of gene rearrangements follows phylogenetic relatedness. We discuss possible causes for the high degree of mt gene rearrangement within phytoseiid mites as well as selection in the mt and nuclear genome tied to the independent evolution of many diverse feeding strategies in the family. Finally, we suggest N. womersleyi should be used instead of the synonym Amblyseius pseudolongispinosus.
