is a boletoid mushroom from the family Boletaceae and was named after its relatively larger basidiocarp and bluish color change when bruised. At present, its mitochondrial genome and phylogenetic relationships with other boletes remain unexplored. In this study, we sequenced the mitochondrial genome of using next-generation sequencing technology and found that its mitochondrial genome, a circular DNA molecule of 38,139 bp, comprised 15 core protein-coding genes, 26 transfer RNA genes and two ribosomal RNA genes. The mitochondrial genome had a base composition of A (37.05%), C (12.08%), G (11.42%) and T (39.45%) with a GC content of 23.50%. A phylogenetic tree based on 20 mitochondrial genomes was constructed, which revealed the phylogenetic relationships of this species with related boletes for the first time.
是一种来自牛肝菌科的牛肝状蘑菇，因其相对较大的担子果以及受伤时会出现蓝色变色而得名。目前，其线粒体基因组以及与其他牛肝菌的系统发育关系尚未得到研究。在本研究中，我们使用下一代测序技术对其线粒体基因组进行了测序，发现其线粒体基因组是一个38,139 bp的环状DNA分子，包含15个核心蛋白质编码基因、26个转运RNA基因和两个核糖体RNA基因。线粒体基因组的碱基组成为A（37.05%）、C（12.08%）、G（11.42%）和T（39.45%），GC含量为23.50%。基于20个线粒体基因组构建了系统发育树，首次揭示了该物种与相关牛肝菌的系统发育关系。
