Abstract

Isodon lophanthoides var. graciliflorus is a folk medicinal herb that is distributed in tropical and subtropical Asia. In this study, the complete plastome of I. lophanthoides var. graciliflorus was assembled and annotated. The plastome is 152,195 bp in length, consisting of a large single-copy (LSC) region of 83,095 bp, a small single-copy (SSC) region of 17,699 bp, and two inverted repeat (IR) regions of 25,701 bp, each. It has 113 genes, including 80 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. The overall GC content of the plastome is 37.6%. Phylogenetic analysis showed that I. lophanthoides var. graciliflorus was sister to Isodon serra.

摘要

Isodon lophanthoides var。graciliflorus是一种民间药草，分布于热带和亚热带亚洲。在这项研究中，I。lophanthoides var的完整质体。graciliflorus进行了组装和注释。质体组长度为152,195 bp，分别由83,095 bp的大单拷贝（LSC）区域，17,699 bp的小单拷贝（SSC）区域和25,701 bp的两个反向重复（IR）区域组成。它具有113个基因，包括80个蛋白质编码基因，29个tRNA基因和4个rRNA基因。质体组的总GC含量为37.6％。系统发育分析表明，I. lophanthoides变种。graciliflorus是Isodon serra的姐姐。
