Phylogeny analysis of a wild species of Paeonia lactiflora from Henan province based on the complete chloroplast genome

摘要

The complete chloroplast genome sequence of a wild Paeonia lactiflora species from Henan province, Paeonia obovata subsp. Willmottiae (Stapf) D. Y. Hong et K. Y. Pan, was applied to support the difference of Paeonia lactiflora by next-generation sequencing. The length of complete chloroplast genome is 152,660?bp, including a large single-copy (LSC) region, a small single-copy (SSC) region, and a pair of identical inverted repeat (IR) regions (IRa and IRb) with length of 84,363?bp, 16,983?bp and 25,657?bp, respectively. Altogether, 115 genes in chloroplast genome were annotated including 81 protein-encoding genes, 30 tRNA genes, and 4 rRNA genes. Paeonia obovata subsp. Willmottiae (Stapf) D. Y. Hong et K. Y. Pan clustered in the clade of Paeonia lactiflora showed a closer relationship with Paeonia sect. Mudan rather than Paeonia Brownii.
