W.C. Wu et C.Y. Wu, a monotypic species and endemic to Southwest China, is a rare and endangered traditional medicinal herb with satisfactory effects on multifold pathology. In order to provide crucial data for protection, we reported and analyzed the complete plastid genome of . as the foundation of germplasm conservation. The complete plastid genome is a typical quadripartite circular molecule of 153,957 bp in length, including a large single copy (LSC) region of 83,972 bp and a small single copy (SSC) region of 17,495 bp separated by two inverted repeat (IR) regions of 26,245 bp. In total of 111 unique genes were predicted, including 78 protein-coding genes (PCGs), 29 transfer RNA genes, and four ribosomal RNA genes. The overall GC content of . is 36.5%. The phylogenetic analysis revealed that . and formed an independent clade with a 100% bootstrap support.
吴氏马先蒿（W.C. Wu et C.Y. Wu）是一个单型物种，为中国西南地区特有，是一种珍稀濒危的传统药用植物，对多种病症有良好疗效。为了提供保护的关键数据，我们报道并分析了吴氏马先蒿的完整质体基因组，作为种质资源保护的基础。完整的质体基因组是一个典型的四分体环状分子，长度为153,957 bp，包括一个83,972 bp的大单拷贝（LSC）区域和一个17,495 bp的小单拷贝（SSC）区域，由两个26,245 bp的反向重复（IR）区域隔开。总共预测出111个独特基因，包括78个蛋白质编码基因（PCG）、29个转运RNA基因和4个核糖体RNA基因。吴氏马先蒿的总体GC含量为36.5%。系统发育分析表明，吴氏马先蒿与[此处原文缺失相关物种名称]形成了一个具有100%自展支持的独立分支。
