摘要:蜱螨亚纲包括两个目:真螨总目和寄螨总目。在已知蜱螨亚纲种类线粒体中,寄螨总目绝大多数种类的线粒体基因组排列模式与节肢动物祖先排列模式保持一致,同时,线粒体基因组中tRNA也保持典型的三叶草二级结构;而在真螨总目线粒体基因组中发现其基因发生高度重排,线粒体tRNA长度极度缩短。为了探究真螨总目线粒体基因组进化特征,本研究对山楂叶螨进行全线粒体基因组扩增和测序,得到山楂叶螨线粒体基因组核酸序列总长13026 bp,环状闭合包含37个基因,其基因高度重排,线粒体tRNA极度缩短。通过与叶螨科、真螨目以及节肢动物线粒体基因组比较得到以下结论:1.基因数量正常没有缺失与增加;2.与叶螨科线粒体基因组排序一致,没有发生重排;3.trnI同时缺失D臂与T臂。28356 毕业论文关键词:山楂叶螨;线粒体基因组;重排
The research of mitochondrial genome in Amphitetranychus viennensis
Abstract:The subclass Acari contains Acariformes and Parasitiformes. In subclass Acari have been sequenced, and the vast majority of send catalogue pattern mitochondrial genome and mite arthropod consistent, at the same time, in the mitochondrial genome tRNA also keep traditional clover secondary structure; Whereas Acariformes found in the mitochondrial genome rearrangement, mitochondrial tRNA extremely shortened. To explore the true mite superorder mitochondrial genome, this research will Amphitetranychus viennensis sequencing, get 13026 bp, hawthorn leaf mites mitochondrial genome chain ring closure contains 37 genes, the height of gene rearrangement, mitochondrial tRNA extremely shortened. With Tetranychidae, Acariformes and arthropods mitochondrial genome is get the following conclusions: 1. The growth in the number of genes and lacking normal; 2. Compared with the leaf mites secco mitochondrial genome sorting is consistent, no rearrangement; 3.trnI lacks both D-arm and T-arm.
