摘要

对报春花（Primula bella）的叶绿体全基因组进行了测序和注释。154,775 bp的基因组具有典型的四部结构：一个85,343 bp的大单拷贝（LSC）区，一个17,772 bp的小单拷贝（SSC）区和两个25,830 bp的反向重复（IR）区。它包含130个基因（86个蛋白质编码基因，36个tRNA， 8个rRNA）。系统发育分析表明，花报春花、环樱报春花和华氏报春花亲缘关系较近，支持小叶报春花组的单系性。该研究提供了宝贵的基因组资源，并对报春花科植物的系统发育有了深入的了解。

The complete chloroplast genome of Primula bella (Primulaceae): a species endemic to the Hengduan Mountains in China.

We sequenced and annotated the complete chloroplast genome of Primula bella (Primulaceae). The 154,775 bp genome displays a typical quadripartite structure: an 85,343 bp large single-copy (LSC) region, a 17,772 bp small single-copy (SSC) region, and two 25,830 bp inverted repeat (IR) regions. It contains 130 genes (86 protein-coding, 36 tRNA, 8 rRNA). Phylogenetic analysis revealed close relationships between P. bella, Primula annulata, and Primula walshii, supporting the monophyly of section Minutissimae. This study provides valuable genomic resources for P. bella and insights into Primulaceae phylogeny.
