L., as a pan-temperate species, it is suitable as a constituent part of grazed grasslands because it can be resistant to winter kill and it contains abundant proteins. In this study, complete chloroplast genome of was explored and phylogenetic analysis was done. The result showed that the whole genome was 124,095 bp long with IR loss. The overall GC content was 35.03%. A total of 109 genes were identified, including 80 protein-coding, 30 transfer RNA, and four ribosome RNA genes. Similar to most of the IRLC plastoms, , and one intron of were lost. The phylogenetic analysis of protein-coding genes from 25 Fabaceae species belonging to IRLC showed that was similar to The chloroplast genome reported here will promote our understanding of the phylogeny and evolution of the genus .
L.作为一种泛温带物种，适合作为放牧草原的组成部分，因为它能抵御冬季冻害且含有丰富的蛋白质。在本研究中，对L.的完整叶绿体基因组进行了探索并开展了系统发育分析。结果表明，整个基因组长度为124,095 bp，存在反向重复序列（IR）缺失。总体GC含量为35.03%。共鉴定出109个基因，包括80个蛋白质编码基因、30个转运RNA基因和4个核糖体RNA基因。与大多数IRLC叶绿体基因组类似，L.的rps16和一个内含子丢失。对属于IRLC的25个豆科物种的蛋白质编码基因进行的系统发育分析表明，L.与[具体物种]相似。此处报道的叶绿体基因组将增进我们对该属系统发育和进化的理解。
