Red root disease in rubber trees, caused by , is a prevalent and severe soil-borne disease in rubber tree cultivation areas. The pathogen exhibits complex infections, with multiple transmission pathways, making the disease highly concealed and difficult to diagnose in its early stages. As a result, prevention and control are challenging, posing a serious threat to rubber production. Currently, the relevant information, evolutionary trajectory, and sequence divergence of the mitochondrial genome of remain unknown. Here, we assembled the complete mitochondrial genome of ,which is 40, 719 bp long and contains 14 protein-coding genes (PCGs), genes encoding small and large ribosomal subunits, 22 mitochondrial-encoded tRNAs, and four hypothetical proteins. The genomic content and characteristics, along with IPS mapping analysis and phylogenetic analysis, reveal a significant similarity between and The results of RNA editing site analysis, codon usage bias and evolutionary pressure analysis reveal that during environmental adaptation, species of Ganoderma may alter certain key PCGs to adopt distinct evolutionary trajectories, differentiating themselves from other fungi in Basidiomycota, while leaving evolutionary traces. Our study provides new insights into the evolutionary direction and pattern of and by exploring the evolutionary trajectory of mitochondrial genomes of . and Ganoderma.
由……引起的橡胶树红根病是橡胶树种植区一种普遍且严重的土传病害。该病原菌表现出复杂的侵染过程，具有多种传播途径，使得这种病害在早期高度隐匿且难以诊断。因此，防治工作具有挑战性，对橡胶生产构成严重威胁。目前，……线粒体基因组的相关信息、进化轨迹和序列差异仍不清楚。在此，我们组装了……的完整线粒体基因组，其长度为40,719 bp，包含14个蛋白质编码基因（PCGs）、编码小核糖体亚基和大核糖体亚基的基因、22个线粒体编码的tRNA以及四个假定蛋白。基因组内容和特征，以及IPS定位分析和系统发育分析表明……与……之间存在显著相似性。RNA编辑位点分析、密码子使用偏好和进化压力分析结果表明，在环境适应过程中，灵芝属物种可能会改变某些关键的PCGs以采用不同的进化轨迹，使其与担子菌门中的其他真菌区分开来，同时留下进化痕迹。我们的研究通过探索……和灵芝线粒体基因组的进化轨迹，为……的进化方向和模式提供了新的见解。
