In this study, we report the complete mitochondrial genome of (Cichlidae fish). The mitochondrial genome is 16 704 bp in length and has a base composition of A (27.6%), T (30.1%), C (15.7%) and G (26.6%), demonstrating a slight bias of high AT content (57.6%). It contains 35 genes (13 protein-coding genes, 22 tRNAs and two rRNAs) and a non-coding A + T rich region (D-loop region). The mitochondial genome of presents a clear bias in nucleotied composition with a positive AT-skew and a negative GC-skew. Except for ND6 gene, all other protein-coding genes were located on the H-strand. gene and gene were overlapped by 5 bp, gene and gene were overlapped by 9 bp. The nucleotide sequence of 13 protein-coding genes of and other 19 Cichlidae species were used for phylogenetic analysis. The result indicated a close relationship with species
在本研究中，我们报道了（丽鱼科鱼类）的完整线粒体基因组。线粒体基因组长度为16704 bp，碱基组成为A（27.6%）、T（30.1%）、C（15.7%）和G（26.6%），显示出较高的AT含量（57.6%）略有偏向。它包含35个基因（13个蛋白质编码基因、22个tRNA和两个rRNA）以及一个富含A+T的非编码区（D环区）。该丽鱼科鱼类的线粒体基因组在核苷酸组成上呈现出明显的偏向，具有正的AT偏斜和负的GC偏斜。除了ND6基因外，所有其他蛋白质编码基因都位于重链上。某基因和某基因重叠5 bp，某基因和某基因重叠9 bp。利用该丽鱼科鱼类的13个蛋白质编码基因的核苷酸序列以及其他19种丽鱼科物种进行系统发育分析。结果表明该丽鱼科鱼类与某物种关系密切
