The complete chloroplast genome sequence of the medicinal plant <i>Dimetia hedyotidea</i> (DC.) T.C.Hsu (Rubiaceae) and its phylogenetic analysis
We assembled and characterized the complete chloroplast genome of Dimetia hedyotidea (DC.) T.C.Hsu. It is 154,385 bp with 37.6% GC. In total, 128 genes were annotated, consisting of 83 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The order and composition of genes were similar to those of other Spermacoceae species. A phylogenetic tree based on the chloroplast genome showed that D. hedyotidea is nested within Spermacoceae and is sister to Exallage chrysotricha. This study enriches the chloroplast genome database for Rubiaceae and provides a foundation for future phylogenetic and genomic studies of the family.
