The complete plastid genome of Chamaecyparis obtusa was sequenced and analyzed in this study. It was found to be 126,821 bp long. The guanine-cytosine content of the whole genome was 35.1%, and there were 83 unique protein-coding genes, 33 tRNAs, and 4 rRNAs. Furthermore, an overlap of 120 bp was found (including trnQ-UUG). The order and organization of these genes were consistent with those of other complete plastid genomes from the Cupressaceae. A phylogenetic tree was constructed according to the 83 protein-coding genes found, which demonstrated that C. obusa had sister relationships within the genus Chamaecyparis.
Keywords: Chamaecyparis obtusa; Cupressaceae; complete chloroplast genome; phylogenetic analysis.
