Complete chloroplast genome of clonal medicinal plant, Glechoma longituba, in China

Glechoma longituba, a typical perennial clonal plant that is recorded in Chinese Pharmacopoeia 2015 version. In this study, the complete chloroplast genome (cpDNA) sequences of Glechoma longituba were reported. The cpDNA is 153,069 bp in length, contains a large single copy region (LSC) of 84,638 bp a small single copy region (SSC) of 17,520 bp, and two inverted repeat (IR) regions of 25,462 bp. The plastome contained 133 genes, including 87 protein-coding, 8 ribosomal RNA, and 37 transfer RNA genes. The overall GC content of the whole genome is 37.8% and the corresponding values of the LSC, SSC, and IR regions are 35.9, 32, and 43.1%, respectively. Phylogenetic analysis based on 19 chloroplast genomes indicates that a close relationship among Mentha longifolia, Mentha spicata, G. longituba, and Prunella vulgaris.
