Abstract:
The medicinal plant Clematis orientalis L. belongs to the family Ranunculaceae. In this study, we determined the complete chloroplast genome sequence of C. orientalis and its phylogenetic relationships with other species. The complete chloroplast genome of C. glauca is 159,518 bp in length, circular in structure, and has four regions including a large single-copy (LSC) region of 79,453 bp; a small single-copy (SSC) region of 17,997 bp; and two inverted repeat (IR) regions of 31,034 bp. The GC content of the genome is 38%, and those of LSC, SSC, and IR regions are 36.2, 31.4, and 42%, respectively. The genome encodes 129 unique genes, including 85 protein-coding genes, 36 tRNA genes, and eight rRNA genes. Phylogenomic analysis reveals that C. orientalis is most closely related to C. aethusifolia. This study contributes to better understanding of phylogenetic relationships of Ranunculaceae.
