The complete chloroplast genome sequence of Paeonia jishanensis (Paeoniaceae), a rare wild tree peony

Abstract

Paeonia jishanensis is endemic in China, and has been proven to be one of the most important ancestral species of cultivated tree peonies. Wild P. jishanensis has been over-exploited and becomes quite rare in China. The wild peony of P. jishanensis was used as an experimental material to sequence the chloroplast genome (cpDNA) by high-throughput sequencing (NCBI accession number: MG991935). The cpDNA of P. jishanensis is a typical quadripartite structure with a length of 152,628 bp, including a large single-copy (LSC) region of 84,292 bp and a small single-copy (SSC) region of 17,044 bp separated by a pair of identical inverted repeat regions (IRs) of 25,646 bp each. The cpDNA contains 112 genes, including 78 protein-coding genes, 30 transfer RNA genes, and 4 ribosomal RNA genes. The result of phylogenomic analysis supports the difference of tree peony from the herbaceous peony.
