Characterization of the complete chloroplast genome of a medicinal plant, Wikstroemia indica (Thymelaeaceae)

Abstract

The complete chloroplast genome of Wikstroemia indica, a medicinal plant with a variety of medicinal functions in treatment for arthritis, whooping cough, cancer, and bacillosis, was generated by de novo assembly using whole genome next-generation sequencing. The plastome was a quadripartite circular with 151,731 bp in length; containing a large single-copy (LSC) region of 86,523 bp and a small single-copy (SSC) region of 12,384 bp; separated by 2 inverted repeat (IR) regions of 26,403 bp each. The chloroplast genome contained 124 genes, including 79 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The GC content in the whole cp genome, LSC region, SSC region, and IR region were 37.4, 34.9, 32.4, and 42.6%, respectively. The phylogenetic tree indicated that W. indica has a close relationship with Stellera chamaejasme with 100% support.
