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)
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 To study the chemical constituents of Dipsacus asper. METHODS Column chromatography on Silica gel and RP-C18 were applied for isolation and purification of the constituents. Their structures were identified by spectral and chemical methods. RESULTS From the crude MeOH fraction of Dipsacus asper, 12 compounds were isolated and identified as(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)
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)
Maca (Lepidium meyenii Walp, 2n = 8x = 64), belonging to the Brassicaceae family, is an economic plant cultivated in the central Andes sierra in Peru (4000-4500 m). Considering that the rapid uplift of the central Andes occurred 5-10 million years ago (Ma), an evolutionary question arises regarding how plants such as maca acquire high-altitude adaptation(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)
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)
