The complete chloroplast genome of Primula vialii (Primulaceae), an ornamental plant

Primula vialii Delavay ex Franch. (1905) is an alpine species with an ornamental value. In this study, we sequenced, assembled, and annotated the chloroplast genome of P. vialii. The results showed that it was a double-stranded, closed circular DNA with 154,897 bp in length, comprising a small single-copy (SSC) region of 17,766 bp, a large single-copy (LSC) region of 85,379 bp and a pair of inverted repeat (IR) regions of 25,876 bp. A total of 113 unique genes were annotated, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. The phylogenetic analysis revealed that P. vialii is closely related to Primula flaccida. The cp genomic data will be useful for systematics and evolutionary studies of Primula.
