Characterization of the complete chloroplast genome of Lonicera similis (Caprifoliaceae)

The complete chloroplast genome of Lonicera similis Hemsl. has been characterized by reference-based assembly using Illumina paired-end data. The circular complete cp genome is 155,463 bp in length, containing a large single copy (LSC) region of 89,282 bp, a small single copy (SSC) region of 18,661 bp, which are separated by a pair of inverted repeat (IR) regions of 23,760 bp. A total of 129 genes were predicted from the cp genome, including 83 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis reveals that L. similis is more closely related to Lonicera japonica Thunb. and Lonicera dasystyla Rehd. Our result will provide a reference for the phylogenetic relationship, plant identification and resource development and utilization of Lonicera species.
