The mitochondrial genome (mitogenome) is essential for identifying species and tracing genetic variation, gene patterns, and evolutionary studies. Here, the mitogenome of was sequenced on the Illumina sequencing platform. This circular mitogenome (28,265 bp) contains 49 genes, including three rRNAs, twenty transfer RNAs (tRNAs), and twenty-six protein-coding genes (PCGs). Nucleotide composition indicates biased AT (68.8%) content. A Group II intronic sequence was identified between two exons of the gene, and this sequence comprises an open reading frame (ORF) that encodes a hypothetical protein. The gene content, annotation, and genetic makeup are identical to those of Halymeniaceae members. The complete mitogenome sequences of the and species were used in a phylogenetic analysis, which revealed that these two genera are monophyletic and that and are closely related. This newly constructed mitogenome will help us better understand the general trends in the development of introns in Halymeniaceae, as well as the evolution of red algal mitogenomes within the Rhodophyta and among diverse algal species.
线粒体基因组（有丝分裂基因组）对于物种鉴定、追踪遗传变异、基因模式和进化研究至关重要。在此，[物种名称]的线粒体基因组在Illumina测序平台上进行了测序。这个环状线粒体基因组（28,265 bp）包含49个基因，包括三个核糖体RNA、二十个转运RNA（tRNA）和二十六个蛋白质编码基因（PCG）。核苷酸组成显示AT含量有偏差（68.8%）。在[基因名称]基因的两个外显子之间鉴定出一个II类内含子序列，该序列包含一个编码假定蛋白质的开放阅读框（ORF）。基因含量、注释和基因组成与海膜科成员相同。[物种名称1]和[物种名称2]物种的完整线粒体基因组序列用于系统发育分析，结果表明这两个属是单系的，并且[物种名称1]和[物种名称2]关系密切。这个新构建的线粒体基因组将有助于我们更好地了解海膜科中[基因名称]内含子发育的总体趋势，以及红藻门内红藻线粒体基因组和不同藻类物种之间的进化情况。
