Abstract

The complete mitochondrial genome of the leafhopper Dworakowska, 1980 was sequenced and annotated from this study. The circular molecule is 14,827 bp in length, including 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and one AT-rich region. The base composition of the genome is as follows: A (42.6%), T (33.9%), G (10.0%), and C (13.4%). 11 PCGs have ATN as the start codon, except for and genes have TTG. The conventional termination codons (TAA or TAG) occur in 11 PCGs, whereas and use incomplete codon (T--) as termination codon. Phylogenetic analysis using 13 PCGs showed that was clustered with two Typhlocybinae species, which was consistent with the conventional classification.

摘要

本研究对叶蝉属（Dworakowska，1980）的完整线粒体基因组进行了测序和注释。该环状分子长度为14,827 bp，包括13个蛋白质编码基因（PCGs）、22个tRNA基因、两个rRNA基因和一个富含AT的区域。基因组的碱基组成为：A（42.6%）、T（33.9%）、G（10.0%）和C（13.4%）。11个PCGs以ATN作为起始密码子，除了和基因以TTG作为起始密码子。11个PCGs使用传统的终止密码子（TAA或TAG），而和基因使用不完全密码子（T--）作为终止密码子。使用13个PCGs进行的系统发育分析表明，与两个小叶蝉亚科物种聚类在一起，这与传统分类一致。
