Analysis of metabolic spectrum characteristics of naturally and cultivated Ophiocordyceps sinensis based on non-targeted metabolomics.

The analysis of the differences in metabolic profiles between naturally Ophiocordyceps sinensis (NO) and cultivated Ophiocordyceps sinensis (CO) is an essential process for the medicinal value mining of Ophiocordyceps sinensis. Non-targeted metabolomics was used to compare the differences in metabolite composition and abundance between NO and CO. Total metabolite composition found that NO is rich in organic acids and derivatives, and CO is rich in lipids and lipid-like molecules.

Metabolomics Combined with Physiology and Transcriptomics Reveal the Response of to Key Metabolic Pathways and Its Degradation Mechanism during Subculture.

During the subculture of filamentous fungi, obvious signs of degradation occur which affect the growth and development of the strain, change the content of metabolites, and interfere with gene expression. However, the specific molecular mechanism of filamentous fungi degradation is still unclear. In this study, a filamentous fungus was used as the research object, and it was continuously subcultured.

Complete chloroplast genomes and phylogenetic relationships of Pedicularis chinensis and Pedicularis kansuensis.

The complete cp genomes of Pedicularis chinensis (GenBank accession number: OQ587614) and Pedicularis kansuensis (GenBank accession number: OQ587613) were sequenced, assembled, and annotated. Their chloroplast (cp) genome lengths were 146,452 bp, and 146,852 bp, respectively; 120 and 116 genes were identified, comprising 75 and 72 protein-coding genes (PCGs), 37 and 36 transfer RNA (tRNA) genes, and 8 and 8 ribosomal RNA (rRNA) genes, for P. chinensis and P.

Evaluation of Quality in 15 Production Areas Using Metabolomics and the Membership Function Method.

is a precious medicinal and edible fungus, which is widely used in body health care and disease prevention. The current research focuses on the comparison of metabolite characteristics between a small number of samples and lacks a comprehensive evaluation of the quality of in a large-scale space. In this study, LC-MS/MS, principal component analysis (PCA), hierarchical cluster analysis (HCA), and the membership function method were used to comprehensively evaluate the characteristics and quality of metabolites in 15 main producing areas of in China.

Revealing Medicinal Constituents of Based on Non-Targeted Metabolomics and 16S rDNA Gene Sequencing Technology.

is a medicinal plant with a long history, but there are few studies on the effects of its medicinal components and endophytic bacteria on the accumulation of secondary metabolites. Therefore, in this study, non-targeted metabolomics techniques and 16s rDNA techniques were used to study from different regions. A total of 1290 metabolites and 437 differential metabolites were identified from all samples.

Effect of Air Drying on the Metabolic Profile of Fresh Wild and Artificial .

Fresh and dried are widely used by the public for medicinal and health purposes. However, the differences between them have not been examined. In this study, fresh wild and artificial (WFC and AFC) were dried to obtain dried wild and artificial (WDC and ADC).

Complete Chloroplast Genomes of , , and : Genome Structures and Comparative and Phylogenetic Analyses.

plants are widely distributed in Asia and Europe; however, their complex phylogenetic relationships have led to many difficulties in phylogenetic studies and interspecific identification. In this study, we assembled, annotated, and analyzed the chloroplast genomes of three plants: , , and . The results showed that the full-length sequences of the three plants were 152,561 bp, 151,452 bp, and 152,293 bp, respectively, which represent the typical quadripartite structure, and the genomes were relatively conserved.

Phylogenetic relationship and characterization of the complete chloroplast genome of subsp. Maximowicz 1877, an ornamental and medicinal plant in China.

As one of the top 10 famous flowers in Chinese tradition, subsp. known as 'beauty in flowers,' which has high ornamental and medicinal value. The complete chloroplast (cp) genome of subsp.

Taxonomic status of the three color variants in sea cucumber (Apostichopus japonicus): evidence from mitochondrial phylogenomic analyses.

Color variation in sea cucumber is one of the most crucial traits affecting price and taste in East Asian countries. However, the relationship and taxonomic status of the three color variants are still unclear. We used 14 samples that covered all three color variants and their geographic distributions, to construct the first phylogeny for the color variants based on the complete mitochondrial genome sequence and a number of tree-building methods (maximum parsimony (MP), maximum likelihood (ML), and Bayesian inference (BI)).
