Characterization of the complete chloroplast genome of Nepeta cataria L. of the herbal medicine from China and phylogenetic relationships

摘要

Nepeta cataria L. is the perennial herb and is a member of the Labiatae family, also has a considerable folkloric reputation in China. In this study, we presented, assembled, and annotated the complete chloroplast genome of N. cataria L. The chloroplast genome size is 153,526?bp, containing a large single-copy region (84,210?bp), a small single-copy region (18,464?bp), and a pair of IR regions (25,624?bp). The overall nucleotide composition is: 30.8% A, 31.1% T, 19.9% C, and 18.2% G, with a total AT content of the chloroplast genome 61.9% and GC content of 38.1%. Nepeta cataria L. whole chloroplast genome contains 134 genes, including 89 protein-coding genes (PCG), 37 transfer RNA (tRNAs), and 8 ribosome RNA (rRNAs). Phylogenetic Neighbor-Joining (NJ) analysis based on 24 herbal medicine plant species chloroplast genomes indicates that N. cataria L. is closely related to N. racemosa. This complete chloroplast genomes can be used for medicinal valuable species research of the Nepeta family.
