The complete plastome of Primula wilsonii, a heterostylous ornamental species.

ABSTRACT

Primula wilsonii Dunn is a perennial herb in section Proliferae Pax of Primula L. with small population sizes in the field. Here, we constructed the complete plastome of the P. wilsonii using Illumina sequencing technology. The circular plastome was 151,677 bp in size, and comprises a large single-copy (LSC) region of 83,510 bp, a small single-copy (SSC) region of 17,765 bp, and a pair of inverted repeats (IR) of 25,201 bp. The GC content was 36.99% overall, with 34.89%, 30.18%, and 42.87% for the LSC, SSC, and IR regions, respectively. The plastome comprised 130 unique genes including 84 protein-coding genes, 37 tRNAs, and 8 rRNAs. The ML phylogenetic analysis based on 17 plastomes in Primulaceae showed a strong sister relationship with P. anisodora in section Proliferae.
