The complete mitochondrial genome of <i>Pseudofabraea citricarpa</i> (Dermateaceae: Helotiales) causing <i>Citrus</i> target spot

<i>Pseudofabraea citricarpa</i> (Dermateaceae: Helotiales) is known as a significant pathogen causing <i>Citrus</i> target spot disease and results in profound yield loss. In the present study, the complete mitochondrial genome (mitogenome) determined based on next-generation sequencing technology. The circular mitogenome (56,935 bp) comprised 14 conserved protein-coding genes (PCGs), 16 ORFs, two ribosomal RNA genes (rns and rnl), one non-coding RNA gene (rnpB), one ribosomal protein S3 (rps3) and 28 transfer RNA (tRNA) genes. The overall base composition is as follows: 36.08% A, 35.25% T, 13.04% C, and 15.63% G, with a GC content of 28.70%. The phylogenetic analysis shows that <i>P. citricarpa</i>, belonging to Dermateaceae, forms a separate clade and is sister to Sclerotiniaceae. The mitogenome of <i>P. citricarpa</i> reported in this study provides more molecular data for further research on the evolutionary relationships of Helotiales.

柑橘生假棒盘孢（Pseudofabraea citricarpa）隶属于柔膜菌目（Helotiales）盘菌科（Dermateaceae），是引发柑橘靶斑病的重要病原菌，可造成严重的产量损失。本研究基于下一代测序技术解析了该菌的完整线粒体基因组（mitogenome）。其环状线粒体基因组全长56935 bp，包含14个保守蛋白编码基因（PCGs）、16个开放阅读框（ORFs）、2个核糖体RNA基因（rns和rnl）、1个非编码RNA基因（rnpB）、1个核糖体蛋白S3（rps3）以及28个转运RNA（tRNA）基因。该基因组的整体碱基组成为：A占36.08%、T占35.25%、C占13.04%、G占15.63%，GC含量为28.70%。系统发育分析结果显示，隶属于盘菌科的P. citricarpa单独形成一个演化支，且与核盘菌科（Sclerotiniaceae）物种互为姊妹群。本研究报道的柑橘生假棒盘孢线粒体基因组，可为后续开展柔膜菌目物种的进化关系研究提供更多分子数据。
