[Comparative analysis of active components and transcriptome between autotetraploid and diploid of Dendrobium huoshanense].

In this study, the roots, stems and leaves of diploid and autotetraploid Dendrobium huoshanense were used as materials to compare their contents of polysaccharides and alkaloids, and the transcriptome sequencing analysis was carried out. The results showed that the contents of polysaccharides and alkaloids in the roots, stems and leaves of tetraploid were 7.6%, 34.

[Transcriptome analysis of seed embryo in dormancy and dormancy release state of Thesium chinense].

We used exogenous GA_3 to break the seed dormancy of Thesium chinense. We used high-throughput sequencing technology was used to sequence the transcriptome of dormant seed embryos and dormancy breaking seed embryos of Th. chinense, and the data was analyzed bioinformatically and systematically.

[Analysis of differential genes related to dormancy release of Paris polyphylla var. chinensis seeds by transcriptome sequencing].

The study aims at exploring the expression of differential genes and related metabolic pathways in the process of seed dormancy release. The dormant embryo and the dormant released embryo of Paris polyphylla var. chinensis were used as the test materials, a new generation high-throughput sequencing methods to sequence the transcriptome of the samples was used to carry out systematic bioinformatics analysis.

A comparative morphological and transcriptomic study on autotetraploid Stevia rebaudiana (bertoni) and its diploid.

Stevia rebaudiana is an important medical plant for producing steviol glycosides (SGs) or stevioside. Autotetraploids (4x = 44) show an increasing level of morphology, physiology and tolerances comparing to diploids (2x = 22). However, little information regarded on the comparative transcriptome analysis between diploid and autotetraploid S.

[Effects of light intensity on photosynthetic capacity and light energy allocation in Panax notoginseng.].

To explore the effects of light intensity on photosynthetic characteristics and light adaptation of the shade-demanding species Panax notoginseng, the responses of photosynthesis to photosynthetic photon flux density, CO and sunflecks in the two-year-old Panax notoginseng were investigated under different levels of light intensity (29.8%, 9.6%, 5.

[In vitro autotetraploid induction and analysis on DNA methylation diversity of Platycodon grandiflorum].

In order to investigate the epigenetic variations between diploid and autotetraploid of Platycodon grandiflorus. The diploid buds of P. grandiflorus were soaked in the mixture of different concentration colchicines and 0.

[Morphology and AFLP analysis of tetraploid plantlets of Atractylodes macrocephala].

In order to investigate the genetic basis of morphological variation of tetraploid plantlets of Atractylodes macrocephala, diploid plantlets were taken as experimental material, sterile filtration colchicine was used to soak 0.5-1.0 cm long buds.

Transcriptome analysis of Panax vietnamensis var. fuscidicus discovers putative ocotillol-type ginsenosides biosynthesis genes and genetic markers.

Background: P. vietnamensis var. fuscidiscus, called "Yesanqi" in Chinese, is a new variety of P.

[FTIR fingerprint spectrograms of traditional Chinese medicine Marsdenia tenacissima].

In this paper, Fourier transform infrared spectroscopy fingerprint analysis of Marsdenia tenacissima samples was used to develop a reliable method of tracing the geographical origins. Forty-eight samples from four provinces of China were analyzed by FTIR. We analyzed and characterized the fingerprints in both the full spectrum peaks and characteristic peaks, then the principal component analysis and the cluster analysis were carried out.

Determination of multiple elements in samples of the medicinal plant Marsdenia tenacissima and estimation of geographic origin via pattern recognition techniques.

Multi-element analysis of the medicinal plant Marsdenia tenacissima was used to develop a reliable method of tracing the geographical source of the samples. The concentrations of 27 elements in 128 samples from 4 provinces in China were analyzed by inductively coupled plasma-atomic emission spectroscopy. Pattern recognition techniques, viz.

[Application and study of HPLC fingerprint of Lonicera japonica for identification of geo-authenticity].

Objective: To establish a chromatographic fingerprint of Lonicera japonica and apply it to identify geo-authentic of L. japonica.

Method: The HPLC was applied in chromatographic separation and data were analysed by "computed aided similarity evaluation" software.

[Determination of 18 organophosphate pesticide residues in Flos Lonicerae].

Objective: To establish an analysical method for the quantitative determination of 18 kinds of organophosphate pesticide residues in Flos Lonicerae.

Method: The pesticides in samples were extracted with acetone by Ultrasonic wave Assistant Extraction (UAE), purified by Solid-Phase Extraction (SPE). Using PFPD detecter gas chromatography with HP-1701 column.
