The complete chloroplast genome of Cinnamomum camphora (L.) Presl., a unique economic plant to China.

ABSTRACT: Cinnamomum camphora (Lauraceae) Presl. is a unique economic plant to China. The complete chloroplast (cp) genome was sequenced and assembled by using Illumina paired-end reads data. The circular cp genome is 152,729 bp in size, including a pair of inverted repeat (IRs) regions of 20,074 bp, a large single copy (LSC) region of 93,688 bp and a small single copy (SSC) region of 18,893 bp. The genome contains 127 unique genes, including 83 protein-coding genes (PCGs), 36 transfer RNA genes (tRNAs), and 8 ribosomal RNA genes (rRNAs). Besides, 19 genes possess a single intron, while another three genes (ycf3, rps12, and clpP) have a couple of introns. The GC content of entire C. camphora cp genome, LSC, SSC, and IR regions are 39.2, 38.0, 33.9, and 44.4%, respectively. Phylogenetic analysis based on the concatenated coding sequences of cp PCGs showed that C. camphora and Cinnamomum verum are closely related with each other within the genus of cinnamomum.
