(Linnaeus, 1762) Huds. is an important annual legume forage that grows in a wide range of climates, from subtropical to temperate. This study aimed to sequence the chloroplast genome of and compare it with other legumes. In this study, we sequenced the entire chloroplast genome of , which has 125,056 base pairs. The total GC content of the chloroplast genome of was 34.4%. From the 110 unique genes of the circular genome, 30 tRNA genes, four rRNA genes, and 76 protein-coding genes were successfully annotated. A maximum likelihood (ML) tree was constructed using the model species and 17 species of the genus. was shown to be phylogenetically closely related to . The nucleotide diversity of the chloroplast genome may provide valuable molecular markers to study chloroplast, genetic breeding, and plant molecular evolution. These findings provide a solid foundation for future research on the molecular biology of the chloroplast.
（林奈，1762年）胡德氏草是一种重要的一年生豆科牧草，生长在从亚热带到温带的广泛气候条件下。本研究旨在对其叶绿体基因组进行测序，并与其他豆科植物进行比较。在本研究中，我们对胡德氏草的整个叶绿体基因组进行了测序，其长度为125,056个碱基对。胡德氏草叶绿体基因组的总GC含量为34.4%。从环状基因组的110个独特基因中，成功注释了30个tRNA基因、4个rRNA基因和76个蛋白质编码基因。使用模式物种和胡德氏草属的17个物种构建了最大似然（ML）树。结果表明，胡德氏草在系统发育上与[具体物种名称]密切相关。叶绿体基因组的核苷酸多样性可能为研究叶绿体、遗传育种和植物分子进化提供有价值的分子标记。这些发现为未来叶绿体分子生物学的研究奠定了坚实的基础。
