praulucens是一种极度濒危的高山观赏植物，是中国西南特有的十倍体野生玫瑰。在这项研究中，我们报道了基于下一代测序从头组装的完整叶绿体基因组。该质体为长157,186 bp的四边圆形，包括一个86,313 bp的大单复制区和一个18,765 bp的小单复制区，由两个26,054 bp的反向重复区隔开。基因组总GC含量为37.2%，LSC、SSC和IR区GC含量分别为35.2%、31.2和42.7%。基因组编码129个基因，包括84个蛋白质编码基因、37个转移RNA基因和8个核糖体RNA基因。
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.
