Jacq is a kind of landscape tree endemic to East Asia. In this study, the complete chloroplast genome of was sequenced. The genome was 159,259 bp in length, with a large single-copy (LSC) region of 88,451 bp, a small single-copy (SSC) region of 19,598 bp, and two inverted repeat (IR) regions of 25,605 bp, each. The genome consisted of 121 genes, including 77 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The phylogenetic results indicated that is not monophyletic and constitute a well-supported clade sister to Sect. . The complete chloroplast genome of will provide important information for phylogenetic and evolutionary studies in Ulmaceae, as well as the other closely related families.
朴树是一种东亚特有的景观树。在本研究中，对朴树的完整叶绿体基因组进行了测序。该基因组长度为159,259 bp，其中大单拷贝（LSC）区域为88,451 bp，小单拷贝（SSC）区域为19,598 bp，两个反向重复（IR）区域各为25,605 bp。该基因组由121个基因组成，包括77个蛋白质编码基因、36个tRNA基因和8个rRNA基因。系统发育结果表明，朴树不是单系的，朴树组和青檀组构成一个得到充分支持的分支，是朴属的姐妹分支。朴树的完整叶绿体基因组将为榆科以及其他近缘科的系统发育和进化研究提供重要信息。
