P. vietnamensis var. fuscidiscus, called “Yesanqi” in Chinese, is a new variety of P. vietnamensis, which was first found in Jinping County, the southern part of Yunnan Province, China. Compared with other Panax plants, this species contains higher content of ocotillol-type saponin, majonoside R2. Despite the pharmacological importance of ocotillol-type(More)
OBJECTIVE In order to establish new molecular markers and to design SSR primers,the SSR information was analyzed in the transcriptome of Pinellia ternata. METHODS The unigenes in transcriptome were filtered and then redundant sequences were removed by the tool of EST-trimmer and cross-match, respectively. Meanwhile, the non-redundant unigenes were(More)
A combination of Fourier transform infrared spectroscopy with chemometrics tools provided an approach for studying Marsdenia tenacissima according to its geographical origin. A total of 128 M. tenacissima samples from four provinces in China were analyzed with FTIR spectroscopy. Six pattern recognition methods were used to construct the discrimination(More)
OBJECTIVE Clone of sucrose synthase of Dendribium officinale and expression analysis, to provide the theory basis for research the relationship between polysaccharide synthesis of D. officinale and sucrose synthase activity. METHOD According to homologous sequence of sucrose synthase gene on GenBank, application the technology of RT-PCR and RACE, clone(More)
Dendrobium officinale Kimura et Migo is a traditional Chinese orchid herb that has both ornamental value and a broad range of therapeutic effects. Here, we report the first de novo assembled 1.35 Gb genome sequences for D. officinale by combining the second-generation Illumina Hiseq 2000 and third-generation PacBio sequencing technologies. We found that(More)
BACKGROUND Danshen (Salvia miltiorrhiza Bunge), also known as Chinese red sage, is a member of Lamiaceae family. It is valued in traditional Chinese medicine, primarily for the treatment of cardiovascular and cerebrovascular diseases. Because of its pharmacological potential, ongoing research aims to identify novel bioactive compounds in danshen, and their(More)
Self-incompatibility (SI) is a widespread and important mating system that promotes outcrossing in plants. Erigeron breviscapus, a medicinal herb used widely in traditional Chinese medicine, is a self-incompatible species of Asteraceae. However, the genetic characteristics of SI responses in E. breviscapus remain largely unknown. To understand the possible(More)
OBJECTIVE To explore breeding method and breed new varieties of Erigeron breviscapus. METHOD Superior individual were selected from natural outcrossing population of E. breviscapus, lines and strains were established and selected and compared. RESULT The scutellarin contents of two E. breviscapus strains of 2003-15 and 2003-6 through line breeding were(More)
OBJECTIVE Scutellarin from Erigeron breviscapus is a flavonoid with remarkable pharmacological activity, whose route of biosynthesis is still fully clear. Chalcone synthase (CHS) is the key enzyme regulating flavonoids biosynthesis, and the aim of this study is to explain the relationship between patterns of the gene expression and scutellarin content(More)
BACKGROUND Erigeron breviscapus (Vant.) Hand-Mazz. is a famous medicinal plant. Scutellarin and chlorogenic acids are the primary active components in this herb. However, the mechanisms of biosynthesis and regulation for scutellarin and chlorogenic acids in E. breviscapus are considerably unknown. In addition, genomic information of this herb is also(More)
