Linnaeus 1753, an annual or biennial herb found in northern China, Mongolia, and Russia, typically grows in stony, sandy grasslands, and pine forests. This study sequenced and reported the complete chloroplast genome of for the first time. The entire circular genome measures 151,689 bp in length, with a GC content of 38.4%. A total of 133 genes were annotated, including 88 protein-coding genes, 37 tRNAs, and eight rRNAs. The genome exhibits a typical quadripartite structure, comprising a large single-copy (LSC 82,820 bp) region, a small single-copy (SSC 17,619 bp) region, and a pair of inverted repeat (IR 25,625 bp each) regions. Phylogenetic analysis using the maximum-likelihood method indicates that is most closely related to Houttuyn. This study provides valuable genomic resources for further research on the phylogenetics and biodiversity of the genus Leonurus.
林奈于1753年记载，这是一种一年生或二年生草本植物，在中国北方、蒙古和俄罗斯均有发现，通常生长在多石、沙质草原和松林中。本研究首次对其叶绿体全基因组进行了测序和报道。整个环状基因组长度为151,689 bp，GC含量为38.4%。共注释了133个基因，包括88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 82,820 bp）区域、一个小单拷贝（SSC 17,619 bp）区域和一对反向重复（每个IR 25,625 bp）区域组成。使用最大似然法进行的系统发育分析表明，该植物与蕺菜属关系最为密切。本研究为进一步研究益母草属的系统发育和生物多样性提供了有价值的基因组资源。
