Aiton 1789, an annual herb, is native to tropical and subtropical Americas and was introduced into many parts of the Old-World including Korea. We determined the genomic characteristics of the complete chloroplast genome of with a assembly strategy. The complete chloroplast genome was 162,858 bp long, and harbored 86 protein coding, 37 tRNA and 8 rRNA. The genome showed the typical quadripartite structure consisting of a large single copy (LSC) (90,580 bp), a small single copy (SSC) (18,570 bp) and a pair of inverted repeats (IRs) (26,854 bp). The phylogenetic tree inferred from chloroplast genomes of 25 taxa, which belong to Euphorbiaceae indicated that the is a monophyletic group and is closely related with , and forming a well-supported clade. Our findings can be valuable for understanding the phylogenetic relationships and the evolution in Euphorbiaceae and will provide basic information for future studies on from genomic perspective.
艾顿草(Aiton 1789)是一种一年生草本植物,原产于热带和亚热带美洲,已被引入包括韩国在内的许多旧世界地区。我们采用一种组装策略确定了艾顿草完整叶绿体基因组的基因组特征。完整的叶绿体基因组长度为162,858 bp,包含86个蛋白质编码基因、37个tRNA和8个rRNA。该基因组呈现典型的四分体结构,由一个大单拷贝(LSC)(90,580 bp)、一个小单拷贝(SSC)(18,570 bp)和一对反向重复序列(IRs)(26,854 bp)组成。从属于大戟科的25个分类单元的叶绿体基因组推断出的系统发育树表明,艾顿草是一个单系类群,并且与其他几种植物密切相关,形成了一个得到充分支持的分支。我们的研究结果对于理解大戟科的系统发育关系和进化具有重要价值,并将从基因组角度为未来艾顿草的研究提供基础信息。
