In this study, the complete mitochondrial genome of (Mitt.) M. Fleisch. in the family Neckeraceae was determined. This mitogenome was 104,716 base pairs in length and contained 40 protein-coding genes, three ribosomal RNA genes, and 24 transfer RNA genes. The overall nucleotide composition was asymmetric (29.5% A, 29.3% T, 21.3% G, and 19.9% C), with a 41.2% G + C content. The gene arrangement was identical to that of most Hypnales genomes. A phylogenetic tree was constructed using the . mitogenome obtained in this study and the complete mitochondrial genome sequences of 23 bryophytes and 3 Marchantiophyta that were publicly available in GenBank. Our phylogenetic analysis revealed that was clustered in a clade with other Hypnalean taxa.
在本研究中，测定了水藓科植物（Mitt.）M. Fleisch. 的完整线粒体基因组。该线粒体基因组长度为104,716个碱基对，包含40个蛋白质编码基因、3个核糖体RNA基因和24个转运RNA基因。总体核苷酸组成不对称（A占29.5%、T占29.3%、G占21.3%、C占19.9%），G + C含量为41.2%。基因排列与大多数灰藓目基因组相同。利用本研究获得的该植物线粒体基因组以及GenBank中公开的23种苔藓植物和3种苔类植物的完整线粒体基因组序列构建了系统发育树。我们的系统发育分析表明，该植物与其他灰藓目类群聚集在一个分支中。
