Characterization And Phylogenetic Analysis Of The Complete Chloroplast Genome Of Camellia Chrysanthoides (Theaceae)

Camellia chrysanthoides H.T.Chang 1979 is an economic species for its high ornamental and medicinal values. In the present work, the complete chloroplast (cp) genome sequence of C. chrysanthoides was assembled and characterized using Illumina paired-end sequencing data. The total cp genome of C. chrysanthoides is 157,439 bp in size, consisting of a small single copy (SSC) and a large single copy (LSC) separated by a pair of inverted repeats (IRs) with 18,265 bp, 88,162 bp, and 25,506 bp, respectively. Further annotation revealed the cp genome encoded 124 genes, including 82 protein-coding genes, 34 tRNA genes, and eight rRNA genes, and the overall GC content of the cp genome is 37.31%. Phylogenetic analysis based on 80 protein-coding genes shows that C. chrysanthoidesis closely related to C. azalea in the genus Camellia.
