近年来，个人的r。基里洛维伊急剧减少。在这里，我们测定并分析了r的完整叶绿体基因组。,cpDNA全长150905 bp，包含一对25864 bp的倒置重复序列（IRs），每个IRs由82131 bp和17046 bp的大单拷贝区（LSC）和小单拷贝区（SSC）分开。基因组包含84个蛋白质编码基因、8个rRNA基因和36个tRNA基因。叶绿体基因组总GC含量为37.8%，而LSC、SSC和IR区GC含量分别为35.8%、31.7和42.9%。最大似然（ML）系统发育分析表明，红景天和crenulatrhodiola聚为一个分支，具有较强的支持值，表明它们的亲缘关系较近。
Rhodiola kirilowiiis a precious Tibetan drug and an extremely endangered plant. In recent years, the number of individuals ofR. kirilowiihas decreased sharply. Here, we determined and analyzed the complete chloroplast genome ofR. kirilowii. The cpDNA was 150,905 bp in length, containing a pair of inverted repeats (IRs) of 25,864 bp each separated by a large and small single copy (LSC and SSC) regions of 82,131 bp and 17,046 bp, respectively. The genome contained 84 protein-coding genes, 8 rRNA genes, and 36 tRNA genes. The overall GC content of the chloroplast genome was 37.8%, whereas the corresponding values of the LSC, SSC, and IR regions were 35.8, 31.7 and 42.9%, respectively. A maximum likelihood (ML) phylogenetic analysis demonstrated thatRhodiola sacraandRhodiola crenulatawere clustered into one clade with strong support values, indicating their closer relationship.
