Bird's nest fungi involve six different genera, but only one of these genera (i.e. ) have available mitochondrial genomes (mitogenomes) to date. In this study, we report the first mitogenome in the genus with K. Das & R.L. Zhao 2013 as a representative. The mitogenome is a circular molecule of 65,793 bp with a GC content of 26.2%. There are a total of 43 genes, including 14 typical protein-coding genes, 26 tRNA genes, two rRNA genes, and one free-standing intergenic open reading frame (ORF). Three introns (two in and one in ) are present in the mitogenome, with each containing an ORF encoding for a LAGLIDADG endonuclease. Phylogenetic analysis based on mitochondrial amino acid sequences confirms the phylogenetic placement of in Nidulariaceae in Agaricales. This study serves as a springboard for future investigation on fungal evolution in Nidulariaceae.
鸟巢菌涉及六个不同的属，但迄今为止，这些属中只有一个属（即 ）拥有可用的线粒体基因组（有丝分裂基因组）。在本研究中，我们报道了以2013年达斯和赵汝亮命名的该属中的首个有丝分裂基因组，以其作为代表。该有丝分裂基因组是一个65,793 bp的环状分子，GC含量为26.2%。共有43个基因，包括14个典型的蛋白质编码基因、26个tRNA基因、2个rRNA基因和1个独立的基因间开放阅读框（ORF）。该有丝分裂基因组中存在三个内含子（两个在 中，一个在 中），每个内含子都包含一个编码LAGLIDADG内切酶的ORF。基于线粒体氨基酸序列的系统发育分析证实了 在伞菌目中鸟巢菌科的系统发育位置。本研究为未来鸟巢菌科真菌进化的研究提供了一个跳板。
