Douglas (Onagraceae) is an annual or perennial herbaceous plant from the prairie of North America. It has become a harmful exotic invading plant in China due to its strong adaptability, fast growth, massive propagation and reproduction. The complete chloroplast (cp) genome of was reported in this study. The size of the complete cp genome of is 161,318 bp in length, including a pair of inverted repeat (IR) regions of 27,402 bp, a large single-copy (LSC) region of 89,132 bp, and a small single-copy (SSC) region of 17,382 bp. A total of 130 genes were annotated, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Comparison of cp genomes of four species from Onagraceae indicated that Onagraceae cp genomes had high nucleotide diversity. In addition, a few highly variable regions of these cp genomes were also detected. The phylogenetic tree showed that is closely related to Thus, the chloroplast genome of can provide valuable genetic information for species identification and phylogenetic analysis.
道格拉斯氏草（柳叶菜科）是一种来自北美草原的一年生或多年生草本植物。由于其适应性强、生长迅速、大量传播和繁殖，它已成为中国一种有害的外来入侵植物。本研究报道了其完整的叶绿体（cp）基因组。该植物完整cp基因组长度为161,318 bp，包括一对27,402 bp的反向重复（IR）区域、一个89,132 bp的大单拷贝（LSC）区域和一个17,382 bp的小单拷贝（SSC）区域。总共注释了130个基因，包括85个蛋白质编码基因、37个tRNA基因和8个rRNA基因。柳叶菜科四个物种的cp基因组比较表明，柳叶菜科cp基因组具有较高的核苷酸多样性。此外，还检测到这些cp基因组的一些高度可变区域。系统发育树表明该植物与另一植物密切相关。因此，该植物的叶绿体基因组可为物种鉴定和系统发育分析提供有价值的遗传信息。
