Abstract

Cinnamomum aromaticum has long been recognized and cultivated in tropical and subtropical Asia for their aromatic bark to produce cinnamon. We reported for the first time the complete plastid genome of C. aromaticum and reconstructed its phylogenetic position. The complete plastid genome is 152,754 bp in length with a quadripartite organization: a large single copy (LSC) region of 93,706 bp and a small single copy (SSC) region of 18,916 bp. Each of the two inverted repeat regions (IRa and IRb) is 20,066 bp. We recovered 128 functional genes, including 84 protein-coding genes, 36 tRNA genes and 8 rRNA genes. The phylogenetic analysis suggested that C. aromaticum and two samples of C. camphora forms a strongly supported clade, which is sister to another cinnamon species of C. verum native to Sri Lanka with strong ultrafast bootstrap support.
