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

We sequenced and annotated the complete chloroplast genome of <i>Primula bella</i> (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 <i>P. bella, Primula annulata</i>, and <i>Primula walshii</i>, supporting the monophyly of section <i>Minutissimae</i>. This study provides valuable genomic resources for <i>P. bella</i> and insights into Primulaceae phylogeny.
