Abstract
Rosa praelucens is a critically endangered alpine ornamental plant and a decaploid wild rose endemic to southwestern China. In this study, we reported its complete chloroplast genome which was de novo assembled based on next generation sequencing. The plastome was a quadripartite circular with 157,186 bp in length, including one large single copy region of 86,313 bp and one small single copy region of 18,765 bp, separated by two inverted repeat regions of 26,054 bp. The overall GC content of the genome was 37.2%, while those of LSC, SSC and IR regions were 35.2, 31.2 and 42.7%, respectively. The genome encoded 129 genes, including 84 protein-coding genes, 37 transfer RNA genes, and eight ribosomal RNA genes. Maximum likelihood phylogenetic analysis showed that sampled species from the genus Rosa formed a monophyletic clade and R. praelucens was sister to other members of the subgenus Rosa.
