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 plastid genome shows a high level of synteny with its close relatives, , , and . Phylogenetic analysis based on 60 complete chloroplast genomes of Primulaceae confirmed its delimitation in .
报春花是一种具有观赏价值的高山物种，为中国西南部横断山脉所特有。在此，我们对其质体全基因组进行了测序和组装，该基因组是一个151,954 bp的环状分子，包含一个大单拷贝区（83,820 bp）和一个小单拷贝区（17,814 bp），由一对反向重复序列（25,160 bp）隔开。质体基因组中有131个基因，其中86个为蛋白质编码基因、37个tRNA基因和8个rRNA基因，其中分别有114个基因、80个编码序列、30个tRNA基因和4个rRNA基因是独特的。该质体基因组与其近缘物种、、和显示出高度的共线性。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它在中的分类地位。
