Red algae are recognized for their health-promoting bioactive substances and dietary fibers, making them important as functional food. In order to identify species and determine phylogenetic relationships, mitochondrial genes serve as important markers. Thus, this study sequenced the complete mitochondrial genome of , compared with Phyllophoraceae species, and performs phylogenetic analysis to reveal its evolutionary position. The genome is 25,992 bp long, has 71.3% of biased AT content, and comprises 24 protein-coding genes (PCGs), 22 tRNA, and three rRNA genes. The overall base composition of its mitochondrial genome was 37.4% for A, 33.9% for T, 14.7% for G, 14.0% for C and 28.7% for GC. The gene content, annotation, and genetic makeup are identical to those of Phyllophoraceae species. Phylogenetic study based on the complete mitochondrial genome and shared mitochondrial genes revealed that the six Phyllophoraceae species form a well-supported clade. Within this clade, . groups with , and together they form a distinct subclade including four species of the . The results indicate that . shares a closer evolutionary relationship with than with species. Future research on is necessary to comprehend the evolutionary history and phylogenetic relationships among species in this genus.
红藻因其具有促进健康的生物活性物质和膳食纤维而闻名，使其成为重要的功能性食品。为了鉴定物种并确定系统发育关系，线粒体基因是重要的标记。因此，本研究对……的完整线粒体基因组进行了测序，与叶状藻科物种进行比较，并进行系统发育分析以揭示其进化位置。该基因组长度为25,992 bp，AT偏斜含量为71.3%，包含24个蛋白质编码基因（PCG）、22个tRNA和3个rRNA基因。其线粒体基因组的总体碱基组成为：A占37.4%，T占33.9%，G占14.7%，C占14.0%，GC占28.7%。基因含量、注释和基因组成与叶状藻科物种相同。基于完整线粒体基因组和共享线粒体基因的系统发育研究表明，六种叶状藻科物种形成了一个得到充分支持的进化枝。在这个进化枝中，……与……聚类，它们共同形成了一个独特的亚进化枝，包括……属的四个物种。结果表明，……与……的进化关系比与……物种的进化关系更密切。有必要对……进行进一步研究，以了解该属物种的进化历史和系统发育关系。
