Analysis on chloroplast genomic characteristics of Cinnamomum bodinieri

Cinnamomum bodinieri is important landscaping and economic tree species, which is rich in essential oils in branches and leaves. However, there are few theoretical researches on the genomics of C. bodinieri. In order to reveal the chloroplast genomic characteristics and phylogenetic relationship of C. bodinieri, the complete chloroplast genome was sequenced based on Illumina platform and assembled through de novo. The genome structure, gene composition, sequence repeats, codon usage bias and phylogeny were analyzed subsequently. Furthermore, the phylogenetic tree was constructed with the chloroplast genome data of the main species of Subfam. Lauroideae. The results were as follows: (1) The complete chloroplast genome of C. bodinieri was 152 727 bp in length including two inverted repeats (IRs) of 20 132 bp, which were separated by large single copy(LSC) of 93 605 bp and short single copy(SSC) of 18 858 bp, respectively, and the GC content was 39.13%. (2) The genome encoded 127 functional genes, including 83 p
