Mitogenomic characterization and phylogenetic positioning of Acropora lutkeni (Scleractinia, Acroporidae)

The complete mitochondrial genome of Acropora lutkeni (Crossland, 1952) (18,480 bp) was assembled and annotated using high-throughput sequencing, revealing 13 PCGs, 2 tRNAs, and 2 rRNAs with AT bias and strand-specific distribution. This study enriches genomic resources and supports research on genetic variation, taxonomy, and evolution within Acropora.本研究采用高通量测序技术对卢氏鹿角珊瑚（Acropora lutkeni, Crossland, 1952）的完整线粒体基因组（全长18480 bp）进行组装与注释，结果显示该基因组共包含13个蛋白编码基因（Protein-Coding Genes, PCGs）、2个转运RNA（transfer RNAs, tRNAs）以及2个核糖体RNA（ribosomal RNAs, rRNAs），且具有AT偏好性与链特异性分布特征。本研究丰富了基因组资源，可为鹿角珊瑚属（Acropora）内的遗传变异、分类学及进化相关研究提供支撑。
