Abstract

Plants of the genus Plectranthus are used for the treatment of digestive problems, skin diseases, and allergies, with a wide variety of uses. Here, the complete chloroplast genome sequence of Plectranthus hadiensis (Benth. ex E.Mey) Codd. 1788 was assembled and characterized for the first time. The full length of the chloroplast genome is 152,484 bp, consisting of a small single-copy region of 17,686 bp, a large single-copy region of 83,380 bp, and a pair of inverted repeats of 51,418 bp. The overall GC content is 37.73%. The chloroplast genome contains 131 unique genes, including 87 protein-coding genes, 36 transfer RNA genes, and eight ribosomal RNA genes. Phylogenetic tree construction based on the complete chloroplast genome sequences of 25 species (23 Nepetoideae, two Ajugoideae) of the Lamiaceae family showed that P. hadiensis exhibited the closest relationship with Isodon.
