Abstract

Here, we successfully assembled the complete chloroplast genome of Rorippa apetala Y.Y. Kim & B.U. Oh, a species endemic to the Korean Peninsula. The chloroplast genome was 154,818 bp long and exhibited a typical quadripartite structure comprising large single-copy (83,847 bp) and small single-copy (18,023 bp) regions, and a pair of inverted repeats (26,474 bp each). A total of 129 genes were encoded, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on the concatenated sequences of 78 protein-coding genes from 25 species revealed a close relationship between R. apetala and Rorippa indica (L.) Hiern, supported by full bootstrap value (100). Future studies employing more informative markers and a broader range of taxa will provide valuable insights into the biogeographical distribution of the genus Rorippa and offer a deeper understanding of the speciation process in R. apetala.

朝鲜半岛特有物种 Rorippa apetala Y.Y. Kim & B.U. Oh（十字花科：十字花属）的完整叶绿体基因组

在此，我们成功地组装了朝鲜半岛特有物种 Rorippa apetala Y.Y. Kim & B.U. Oh 的完整叶绿体基因组。叶绿体基因组长 154,818 bp，呈典型的四方结构，包括大的单拷贝区（83,847 bp）和小的单拷贝区（18,023 bp），以及一对倒位重复区（各 26,474 bp）。共编码了 129 个基因，包括 84 个蛋白质编码基因、37 个 tRNA 基因和 8 个 rRNA 基因。基于来自 25 个物种的 78 个蛋白编码基因的序列的系统进化分析表明，R. apetala 与 Rorippa indica (L.) Hiern 之间的关系密切，并得到了全引导值（100）的支持。未来的研究将采用更多的信息标记和更广泛的分类群，这将为研究 Rorippa 属的生物地理分布提供有价值的见解，并加深对 R. apetala 的物种分化过程的理解。
