Abstract

Primula homogama F. H. Chen & C. M. Hu (Primulaceae) is endemic to the Emei Mountain of China. In this study, we characterized the complete chloroplast genome of P. homogama based on next-generation sequencing (NGS). The complete chloroplast genome of P. homogama was 154,677 bp in size with a typical quadripartite structure, containing a large single-copy (LSC) region of 85,299 bp and a small single-copy (SSC) region of 17,816 bp. These two regions were separated by a pair of inverted repeat regions (IRs), each of 25,781 bp. A total of 130 functional genes were encoded, consisted of 86 protein-coding genes (PCG), 36 tRNA genes, and eight ribosomal RNA (rRNA) genes.
