Twenty-four mitogenomes of the mushroom corals (Fungiidae), representing 18 species from 12 genera, were sequenced and annotated. These mitogenomes exhibit high similarity, each containing the same 13 protein-coding genes (PCGs) and two rRNA genes as other scleractinian corals. Compared to the genes, the intergenic regions (IGRs) are more diverse. Interestingly, minisatellite sequences were identified in the IGRs between and (IGR ) and between and (IGR ) of most Fungiidae mitogenomes. Primarily due to the existence of minisatellites in IGR , the length of Fungiidae mitogenomes varies from 16,292 to 17,399 bp. Similar to the phylogenetic tree based on partial COI sequences, Bayesian phylogenetic trees constructed using 13 PCGs, IGR and IGR divide Fungiidae into four distinct clades. However, the latter three trees provide a higher resolution of genus- and species-level evolutionary relationships. This mitogenome dataset will be valuable for better understanding the phylogeny of Fungiidae. The diverse IGRs in these mitogenomes may serve as a useful resource for developing Fungiidae DNA barcodes, while the identified minisatellites can facilitate studies on the population biology of Fungiidae.
对代表12个属18个物种的24个蘑菇珊瑚(菌珊瑚科)线粒体基因组进行了测序和注释。这些线粒体基因组表现出高度相似性,每个都包含与其他石珊瑚相同的13个蛋白质编码基因(PCG)和两个rRNA基因。与基因相比,基因间隔区(IGR)更为多样。有趣的是,在大多数菌珊瑚科线粒体基因组的 和 之间的IGR(IGR )以及 和 之间的IGR(IGR )中鉴定出了微卫星序列。主要由于IGR 中存在微卫星,菌珊瑚科线粒体基因组的长度在16,292至17,399 bp之间变化。与基于部分COI序列的系统发育树相似,使用13个PCG、IGR 和IGR 构建的贝叶斯系统发育树将菌珊瑚科分为四个不同的分支。然而,后三棵树提供了更高分辨率的属和种水平的进化关系。这个线粒体基因组数据集对于更好地理解菌珊瑚科的系统发育将是有价值的。这些线粒体基因组中多样的IGR可能作为开发菌珊瑚科DNA条形码的有用资源,而鉴定出的微卫星可以促进对菌珊瑚科种群生物学的研究。
