Abstract

We sequenced the complete mitochondrial genome of Schoutedenia ralumensis. The mitogenome is 16,051 bp long with an A + T content of 84.5%, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, a control region, and an aphid-specific repeat region located between trnE and trnF. All protein-coding genes are initiated by ATN and terminated with TAA or TAG except for cox1 and nad5. All transfer RNAs display the typical clover-leaf secondary structure except for trnS (AGN). The unique repeat region is 974 bp long, in which a 305-bp repeat unit repeats 3.19 times. The phylogenetic tree supports a sister relationship of S. ralumensis and Greenidea psidii.

摘要

我们对Schoutedenia ralumensis的完整线粒体基因组进行了测序。有丝分裂基因组长16051 bp，A + T含量为84.5％，包括13个蛋白质编码基因，22个转移RNA基因，2个核糖体RNA基因，一个控制区以及位于trnE和trnF之间的蚜虫特异性重复区。除cox1和nad5外，所有蛋白质编码基因均由ATN启动，并以TAA或TAG终止。除trnS（AGN）外，所有转移RNA均显示典型的三叶草叶二级结构。独特的重复区域长974 bp，其中305 bp的重复单元重复3.19次。系统发育树支持S. ralumensis的姐妹关系和Greenidea psidii。
