法国报春花。是中国西南横断山脉特有的一种具有观赏价值的高山植物。在这里，我们对其质体完整基因组进行了测序和组装，该基因组是一个151,954 bp的圆形分子，包含一个大单拷贝（83,820 bp）和一个小单拷贝（17,814 bp）区域，由一对反向重复序列（25,160 bp）分隔。质体中有131个基因、86个蛋白质编码基因、37个trna和8个rnas，其中114个基因、80个CDSs、30个trna和4个rnas是唯一的。calliantha质体基因组与其近亲chionantha、P. purdomii和P. woodwardii具有高度的同源性。基于报春花科60个完整叶绿体基因组的系统发育分析证实了报春花属的划分。
Primula calliantha Franch. is an alpine species with an ornamental value that is endemic to the Hengduan Mountains of southwest China. Here, we sequenced and assembled its plastid complete genome, which is a circular molecule of 151,954 bp and contains a large single-copy (83,820 bp) and a small single-copy (17,814 bp) region, separated by a pair of inverted repeats (25,160 bp). There are 131 genes, 86 protein-coding, 37 tRNAs, and 8 rRNAs in the plastome, of which 114 genes, 80 CDSs, 30 tRNAs, and 4 rRNAs are unique, respectively. The P. calliantha plastid genome shows a high level of synteny with its close relatives, P. chionantha, P. purdomii, and P. woodwardii. Phylogenetic analysis based on 60 complete chloroplast genomes of Primulaceae confirmed its delimitation in Primula.
