( Nutt., 1818) is an annual barley that is native to the west of the North America and widespread in southern United States and tropical America. In this study, we have provided the first complete characterization of the chloroplast genome of . Our research revealed that the circular chloroplast genome of consists of a large single-copy region (LSC: 80,853 bp), a small single-copy region (SSC: 12,745 bp), and a pair of inverted repeat regions (IRs: 21,587 bp), totaling 136,772 bp in length. Within the chloroplast genome of , 91 protein-coding genes, 38 tRNA genes, and ten rRNA genes were identified. To determine the evolutionary relationship of species with reported chloroplast genome sequences, we constructed a phylogenetic tree using the entire chloroplast genome sequences. The evolutionary position of corresponds to its geographical location. The chloroplast genome of provided in this study may have significant implications for the phylogenetic study of Poaceae species.
（努特，1818年）是一种一年生大麦，原产于北美西部，在美国南部和热带美洲广泛分布。在本研究中，我们首次对其叶绿体基因组进行了完整的特征描述。我们的研究表明，其环状叶绿体基因组由一个大单拷贝区域（LSC：80,853 bp）、一个小单拷贝区域（SSC：12,745 bp）和一对反向重复区域（IRs：21,587 bp）组成，总长136,772 bp。在其叶绿体基因组中，鉴定出了91个蛋白质编码基因、38个tRNA基因和10个rRNA基因。为了确定该物种与已报道叶绿体基因组序列的进化关系，我们使用整个叶绿体基因组序列构建了系统发育树。其进化位置与其地理位置相对应。本研究中提供的该物种叶绿体基因组可能对禾本科物种的系统发育研究具有重要意义。
