Characterization of the complete plastid genome of a Chinese Endangered Species Rosa rugosa Thunb.

Rosa rugosa Thunb. is an endangered species in China and also an invasive species in Northern Europe with important ornamental value, economic value, and breeding value, especially wild R. rugosa. In this study, the complete plastid genome of R. rugosa was sequenced and analyzed using next-generation DNA sequencing technology. We subjected the genomic analyses and constructed the maternal phylogenetic relationships. The complete plastid genome was 157,110 bp in length, including a large single copy (LSC) region of 86,214 bp, a small single copy (SSC) region of 18,820 bp and a pair of inverted repeat (IR) regions of 26,038 bp. In total of 116 unique genes were identified, containing 79 protein-coding genes (PCGs), 30 transfer RNA genes, four ribosomal RNA genes, and three pseudogenes (psi ycf1, psi ycf15, psi ycf68), respectively. The phylogenetic analysis revealed that R. rugosa and R. praelucens formed an independent clade with a 100% bootstrap support.
