The complete chloroplast genome sequence of the medicinal plant Paeonia delavayi Franchet. (Paeoniaceae).

Paeonia delavayi is a medicinal plant commonly used in southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of P. delavayi to investigate its phylogenetic relationship in the family Paeoniaceae. The chloroplast genome of P. delavayi was 152,872 bp in length with 38.4% overall GC content, including a large single copy (LSC) region of 84,523 bp, a small single copy (SSC) region of 17,053 bp and a pair of inverted repeats (IRs) of 25,646 bp. The cp genome contained 105 genes, including 75 protein coding genes, 27 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated P. delavayi was closely related to P. ludlowii.
