Lour. is a deciduous tree species belonging to the family of Euphorbiaceae, distributed in southeast Asia. Here, we report and characterize the complete plastome of Lour. The complete plastome is of 164,506 bp in length with a typical structure and gene content of angiosperm plastome, including two inverted repeat (IRs) regions of 27,965 bp, a large single-copy (LSC) region of 91,427 bp and a small single-copy (SSC) region of 17,149 bp. The plastome contains 130 genes, consisting of 81 protein-coding genes (six of which are repetitive in IR), 38 tRNA genes (seven of which are repetitive in IR), seven rRNA genes (5S rRNA, 4.5S rRNA, 23S rRNA and 16S rRNA) (three of which are repetitive in the IR), and four pseudogenes. The overall G/C content in the plastome of Lour. is 35.8%. The complete plastome sequence of Lour. will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Euphorbiaceae.
Lour.是一种属于大戟科的落叶树种，分布于东南亚。在此，我们报道并描述了Lour.的完整质体基因组。该完整质体基因组长度为164,506 bp，具有被子植物质体基因组的典型结构和基因组成，包括两个27,965 bp的反向重复（IR）区域、一个91,427 bp的大单拷贝（LSC）区域和一个17,149 bp的小单拷贝（SSC）区域。该质体基因组包含130个基因，由81个蛋白质编码基因（其中6个在IR中重复）、38个tRNA基因（其中7个在IR中重复）、7个rRNA基因（5S rRNA、4.5S rRNA、23S rRNA和16S rRNA）（其中3个在IR中重复）和4个假基因组成。Lour.质体基因组中的总体G/C含量为35.8%。Lour.的完整质体基因组序列将为该物种的保护遗传学以及大戟科的系统发育研究提供有用的资源。
