Abstract

Mentha haplocalyx is an important medicinal and edible plant. Now, the complete chloroplast (cp) genome of M. haplocalyx was assembled and annotated. The cp genome of M. haplocalyx was 152,048 bp and contained two short inverted repeat regions (25,608 bp) which were separated by a small single copy region (17,654 bp) and a large single copyregion (83,179 bp). The cp genome encodes 113 unique genes, including 79 protein-coding genes, 30 transfer RNA genes and 4 ribosomal RNA genes. The topology of the phylogenetic tree showed that M. haplocalyx and M. spicata formed a monophyletic clade and clustered together with genus Dracocephalum.

摘要

薄荷菜是一种重要的药用和食用植物。现在，已组装并注释了haplocalyx的完整叶绿体（cp）基因组。的CP基因组M. haplocalyx是152048 bp和包含其通过一小的单拷贝区（17654碱基对）和大单copyregion（83179 bp）的分离的两个短反向重复区域（25608碱基对）。cp基因组编码113个独特基因，包括79个蛋白质编码基因，30个转移RNA基因和4个核糖体RNA基因。系统发育树的拓扑结构表明，haplocalyx和sp。sp。形成了一个单系进化枝，并与Dracocephalum属一起聚集。
