Abstract

Ligusticum jeholense is an important medicinal plant. Chloroplast genome information is helpful for the development of molecular markers and the study of plant phylogeny. In this study, we report the complete chloroplast genome sequence of L. jeholense. The genome sequence is 148,493 bp in size (GenBank accession number MN652885), with 37.25% GC contents. There are 127 genes in the genome, including 83 known protein-coding genes (PCGs), 36 transfer RNAs (tRNAs), and 8 ribosomal RNAs (rRNAs). The maximum-likelihood method are used to construct phylogenetic tree of 32 species. These data will provide certain theoretical basis for plant genetics research.

摘要

gust药是重要的药用植物。叶绿体基因组信息有助于分子标记的发展和植物系统发育的研究。在这项研究中，我们报告了L. jeholense的完整叶绿体基因组序列。基因组序列大小为148,493 bp（GenBank登录号为MN652885），GC含量为37.25％。基因组中有127个基因，包括83个已知的蛋白质编码基因（PCG），36个转移RNA（tRNA）和8个核糖体RNA（rRNA）。采用最大似然法构建32种系统发育树。这些数据将为植物遗传学研究提供一定的理论基础。
