Characteristic and phylogenetic analyses of chloroplast genome for Mentha haplocalyx (Lamiaceae)

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.
