Abstract

Leucoagaricus naucinus (Fr.) Singer is a mycorrhizal fungus widely distributed in the northern Hemisphere. In the present study, the complete mitochondrial genome of Leucoagaricus naucinus was sequenced, assembled, and annotated. The L. naucinus mitochondrial genome was composed of circular DNA molecules, with the total size of 61,434 bp. The GC content of the L. naucinus mitochondrial genome was 26.07%. A total of 30 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, and 26 transfer RNA (tRNA) genes were detected in the L. naucinus mitochondrial genome. Phylogenetic analysis based on combined mitochondrial gene dataset indicated that the L. naucinus exhibited a close relationship with Agaricus bisporus.

Leucoagaricus naucinus (Fr.) Singer 是一种广泛分布于北半球的菌根真菌。在本研究中，对Leucoagaricus naucinus的完整线粒体基因组进行了测序、组装和注释。 L. naucinus线粒体基因组由环状DNA分子组成，总大小为61,434 bp。 L. naucinus线粒体基因组的GC含量为26.07%。在L. naucinus线粒体基因组中总共检测到 30 个蛋白质编码基因 (PCG)、2 ​​个核糖体 RNA (rRNA) 基因和 26 个转移 RNA (tRNA) 基因。基于组合线粒体基因数据集的系统发育分析表明， L. naucinus与双孢蘑菇表现出密切的亲缘关系。
