本研究首次报道了一种真菌白蚁Macrotermes natalensis的线粒体全基因组，全长16325 bp。该mt基因组包含13个蛋白质编码基因、22个转移RNA基因、2个核糖体RNA基因和1个控制区（D-loop）。总碱基组成为A的44.1%、T的21.5%、G的11.5%、C的22.9%，因此A和T的比例（65.6%）远高于G和C。除ND1、ND4、ND4L、ND5 4个亚基基因和8个tRNA基因外，大部分基因分布在h链上。所有蛋白质编码基因都以ATN密码子开始，以规范终止密码子（TAA/TAG）或单个T （T- -）终止。本文报道的线粒体全基因组序列为大白蚁属增加了新的遗传资源，对大白蚁属的系统发育和系统分析具有重要意义。
In this study, the complete mitochondrial genome of a fungus-growing termite, Macrotermes natalensis, with the total length of 16,325 bp, is reported for the first time. This mtgenome harbors 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 control region (D-loop). The total base composition is 44.1% of A, 21.5% of T, 11.5% of G, and 22.9% of C, so the percentage of A and T (65.6%) is much higher than that of G and C. Most of the genes are distributed on H-strand, except for four subunit genes (ND1, ND4, ND4L, ND5) and eight tRNA genes. All protein-coding genes start with an ATN codon, and terminate with the canonical stop codon (TAA/TAG) or a single T (T- -). The complete mitochondrial genome sequence reported here adds a new genetic resource for the genus Macrotermes and might be useful for phylogenetic and systematic analyses within the genus Macrotermes.
