摘要
本研究首次获得了roseoflavus Butyriboletus (Hai B. Li & Hai L. Wei) D. Arora & J.L. Frank 2014菌株MG29和Bro1的线粒体全基因组序列。MG29 （36,551 bp）和Bro1 （36,544 bp）有丝分裂基因组具有较高的相似性，GC含量分别为23.13%和23.14%。两个基因组编码15个核心蛋白编码基因（PCGs）， 26个不同的开放阅读框（orf）， 24个内含子orf， 26个tRNA基因和2个rRNA基因。利用贝叶斯推理（BI）和最大似然分析（ML）对14个连接的线粒体PCGs进行系统发育分析，发现roseoflavus形成了一个与Boletus ornatipes和Boletus speciosus密切相关的独特分支。该研究促进了我们对外生菌根真菌有丝分裂基因组多样性的认识。
The first two complete mitochondrial genomes of Butyriboletus roseoflavus (Hai B. Li & Hai L. Wei) D. Arora & J.L. Frank 2014 (Boletales: Boletaceae) and phylogenetic analysis.
This study presents the first complete mitochondrial genome sequences of Butyriboletus roseoflavus (Hai B. Li & Hai L. Wei) D. Arora & J.L. Frank 2014 strains MG29 and Bro1. The mitogenomes of MG29 (36,551 bp) and Bro1 (36,544 bp) exhibit high similarity, with GC contents of 23.13% and 23.14%, respectively. Both genomes encode 15 core protein-coding genes (PCGs), 26 distinct open reading frames (ORFs), 24 intronic ORFs, 26 tRNA genes, and two rRNA genes. Phylogenetic analysis using Bayesian inference (BI) and maximum-likelihood (ML) of 14 concatenated mitochondrial PCGs revealed that B. roseoflavus forms a distinct clade closely related to Boletus ornatipes and Boletus speciosus. The study advances our understanding of mitogenome diversity in ectomycorrhizal fungi.
