Modified Xijiao Dihuang (XJDH) decoction has been shown to exert powerful neuroprotective properties in clinical ischemic stroke treatment. It consists of 4 Chinese herbs: Buffalo Horn, Paeonia suffruticosa Andrews, Rehmannia glutinosa (Gaertn.) DC, and Paeonia lactiflora Pall. In the present study, the neuroprotective effect and specific mechanisms of XJDH in protecting PC12 cells from oxygen-...

The miRNA, a kind of endogenous non-coding small RNA, plays an essential role in regulation gene expression plants. Quantitative real-time PCR (qRT-PCR) assay is one the most common methods used for quantification miRNA expression, and levels are normalized by comparing with reference genes. present study was intended to identify appropriate genes normalizing level various developmental stages ...

The MPT transports Pi to synthesize ATP. PsMPT, a chilling-induced gene, was previously reported to promote energy metabolism during bud dormancy release in tree peony. In this study, the regulatory elements of PsMPT promoter involved in chilling response were further analyzed. The PsMPT transcript was detected in different tree peony tissues and was highly expressed in the flower organs, inclu...

Root pruning during early root development can optimize the structure of woody plants. To determine effects on tree peony (Paeonia suffruticosa), seedlings cultivar ‘Fengdanbai’ were subjected to varying degrees or different styles pruning. Various indexes analyzed, including anatomical root, vitality, activity levels antioxidant enzymes, and contents endogenous hormones their ratios. Comprehen...

The use of highly discriminatory methods for the identification and characterization of genotypes is essential for plant protection and appropriate use. We utilized the RAPD method for the genetic fingerprinting of 11 plant species of desert origin (seven with known medicinal value). Andrachne telephioides, Zilla spinosa, Caylusea hexagyna, Achillea fragrantissima, Lycium shawii, Moricandia sin...

Tree peony (Paeonia suffruticosa Andrews) is an important traditional flower in China. Besides its beautiful flower, the leaf of tree peony has also good ornamental value owing to its leaf color change in spring. So far, the molecular mechanism of leaf color change in tree peony is unclear. In this study, the pigment level and transcriptome of three different color stages of tree peony leaf wer...
