This study presents the first-ever complete chloroplast (cp) genome sequence of Bunge 1874, a member of the Fabaceae family. The cp genome spans 126,996 base pairs and includes 109 genes, comprising 76 protein-coding genes, 29 tRNA genes, and four rRNA genes. Notably, the genome lacks an inverted repeat (IR) region. Additionally, we constructed phylogenetic trees for 34 species within Trib. Galegeae, employing both maximum likelihood (ML) and Bayesian inference (BI) methods. These analyses robustly support the monophyly of the species, evidenced by high bootstrap values (BP = 100) and posterior probabilities (PP = 1). Within this clade, exhibits a sister relationship with other species. Our findings provide valuable insights into the genetic makeup and evolutionary relationships of within the Galegeae tribe.
本研究展示了豆科植物Bunge 1874的首个完整叶绿体（cp）基因组序列。该cp基因组跨度为126,996个碱基对，包含109个基因，其中有76个蛋白质编码基因、29个tRNA基因和4个rRNA基因。值得注意的是，该基因组缺乏反向重复（IR）区域。此外，我们采用最大似然法（ML）和贝叶斯推断法（BI）为山羊豆族内的34个物种构建了系统发育树。这些分析有力地支持了该物种的单系性，高自展值（BP = 100）和后验概率（PP = 1）证明了这一点。在这个分支中， 与其他 物种呈现出姐妹关系。我们的研究结果为山羊豆族内 的遗传组成和进化关系提供了有价值的见解。
