Valenciennes 1835 is an essential species for examining reef ecosystems; however, its mitochondrial genome has not been studied. In this research, the mitogenome of was sequenced and characterized. The results revealed a circular genome of 16,505 bp that was composed of A (28.1%), C (31.3%), G (14%), and T nucleotides (26.6%). The genome contained 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. Most genes of the mitogenome were transcribed on the heavy strand (H-strand), whereas and eight tRNA genes (including , , , , , (1), , and ) were transcribed on the light strand (L-strand). Comparative analysis revealed a high degree of conservation of gene content and order among the mitogenomes. Phylogenetic analysis inferred from whole mitogenomes exhibited a close relationship between and . The newly completed mitogenome of provides essential genomic data for further studies on population genetics and the evolution of the genus and the Siganidae family.
瓦伦西恩斯1835年（物种）是研究珊瑚礁生态系统的重要物种；然而，其线粒体基因组尚未得到研究。在本研究中，对（该物种）的线粒体基因组进行了测序和特征分析。结果显示其环状基因组为16505 bp，由A（28.1%）、C（31.3%）、G（14%）和T核苷酸（26.6%）组成。该基因组包含13个蛋白质编码基因、22个转运RNA基因和两个核糖体RNA基因。线粒体基因组的大多数基因在重链（H链）上转录，而（某些基因）和8个tRNA基因（包括，，，，，（1），，和）在轻链（L链）上转录。比较分析显示，（该物种的）线粒体基因组之间在基因内容和顺序上具有高度保守性。从整个线粒体基因组推断的系统发育分析表明，（该物种）与（另一物种）之间关系密切。新完成的（该物种）线粒体基因组为进一步研究（该物种所在）属以及蓝子鱼科的种群遗传学和进化提供了重要的基因组数据。
