The complete chloroplast genome sequence of Cinnamomum septentrionale (Lauraceae) from Sichuan Province, China, a medicinal plant and phylogenetic analysis

Abstract

Cinnamomum septentrionale is a commercially important timber tree and wild spice plant classified in the Lauraceae. Here we sequenced the complete plastid genome of C. septentrionale to contribute to its phylogenetics and bioinformatics. The chloroplast genome of C. septentrionale is 152,729 bp in length and includes a large single copy (LSC) region of 93,639 bp, a small single copy (SSC) region of 18,858 bp, and two inverted repeat (IR) regions of 20,114 bp. The GC content of LSC, SSC, IR and the whole genome is 37.9%, 33.8%, 44.4%, and 39.1%, respectively. There are 128 genes, including 84 protein-coding, 36 tRNA, and eight rRNA genes. The phylogenetic analysis resolved C. septentrionale in a sister position to C. glanduliferum. The complete chloroplast genome sequence of C. septentrionale provides valuable genomic information for future systematic studies on Cinnamomum.
