The phylogeographic structure and conservation genetics of the endangered tree peony, Paeonia rockii (Paeoniaceae), inferred from chloroplast gene sequences

Conservation Genetics, 2011
The endangered species Paeonia rockii is the most important ancestral species of the cultivated tree peonies. These well-known ornamental plants are termed the ‘King of Flowers’ in China. In this study, we investigated the genetic diversity and phylogeographic structure of 335 wild samples from 20 populations throughout the entire distributional range ...

Application of GC × GC coupled with TOF–MS for the trace analysis of chemical components and exploration the characteristic aroma profile of essential oils obtained from two tree peony species (Paeonia rockii and Paeonia ostii)

European Food Research and Technology, 2021
Tree peony essential oil (EO) is a critical material for flavor and function in the industrial fields of perfume, medicine and food. To conduct an overall analysis of different varieties of tree peony EOs, the composition, aroma characteristics and antioxidant activity of ZiBan and FengDan EOs were analyzed by two-dimensional gas chromatography and ...

Influence of pollen sources on the expression of FA and TAG biosynthetic pathway genes in seeds of Paeonia rockii during the rapid oil accumulation

Scientia Horticulturae, 2019
Abstract Tree peony has been widely planted as an excellent oil crop with high proportion of α-linolenic acid (ALA) in its seeds. It was reported that pollen sources have clear effects on fatty acid (FA) composition of its kernels. Nevertheless, the molecular basis of this novel phenomenon is poorly understood.
