To understand the synonymous codon usage pattern in mitochondrial genome of Antheraea assamensis, we analyzed the 13 mitochondrial protein‐coding genes of this species using a bioinformatic approach as no work was reported yet. The nucleotide composition analysis suggested that the percentages of A, T, G,and C were 33.73, 46.39, 9.7 and 10.17, respectively and the overall GC content was 19.86, that is, lower than 50% and the genes were AT rich. The mean effective number of codons of mitochondrial protein‐coding genes was 36.30 and it indicated low codon usage bias (CUB). Relative synonymous codon usage analysis suggested overrepresented and underrepresented codons in each gene and the pattern of codon usage was different among genes. Neutrality plot analysis revealed a narrow range of distribution for GC content at the third codon position and some points were diagonally distributed, suggesting both mutation pressure and natural selection influenced the CUB.

阿萨姆邦（Assam）uga蚕（Muga）An药（Antheraea assamensis）线粒体蛋白编码基因的分析

了解as蚕An线粒体基因组中的同义密码子使用方式，我们使用生物信息学方法分析了该物种的13个线粒体蛋白质编码基因，因为尚未有任何报道。核苷酸组成分析表明，A，T，G和C的百分比分别为33.73、46.39、9.7和10.17，总GC含量为19.86，即低于50％，并且基因富含AT。线粒体蛋白质编码基因的平均有效密码子数为36.30，表明密码子使用偏倚（CUB）低。相对的同义密码子使用分析表明，每个基因中密码子的代表数量过多和不足，并且各基因之间的密码子使用方式不同。中性图分析显示，GC含量在第三个密码子位置的分布范围狭窄，并且某些点呈对角分布，
