[Construction of Panax ginseng root yeast library and screening of interacting proteins of PgD14 and Pgpht2-1].

To construct a high-quality Panax ginseng cDNA library, transcription factors binding to the P. ginseng PgD14 gene promoter were screened by yeast one-hybrid, and proteins interacting with the P. ginseng Pgpht2-1 gene-encoded protein were screened by yeast two-hybrid.

[Study on differences in metabolism and transcription of ginseng seeds after morphological post ripening by space flight].

To explore the difference in metabolism and transcription between seeds experiencing space flight and ground seeds after morphological post ripening, this study utilized ginseng seeds experiencing space flight and ground seeds as materials. Metabolomics and transcriptomics analyses were conducted using ultra-high performance liquid chromatography-mass spectrometry(UPLC-MS) and high-throughput transcriptome sequencing(RNA-seq) technologies, so as to identify differential terpenoid metabolites, differential endogenous hormones, and differentially expressed genes. The results showed that through metabolomics analysis, a total of 22 differential terpenoid metabolites were identified in the experimental and control groups, including chikusetsusaponin FK_7, ginsenoside F_2, ginseno-side K, majoroside R_1, ginsenoside Re_5, 12-hydroxyabietic acid, etc; through transcriptomics analysis, 15 differential terpenoid metabolism-related differentially expressed genes were identified in the experimental and control groups, including FCase, AACT, PMK, etc, and these genes were integrated into the pathway based on the MEP and MVA.

[Interaction between root exudates of medicinal plants and rhizosphere microorganisms and its application in ecological planting of Chinese medicinal materials].

The rhizosphere is an important place for material exchange between medicinal plants and soil. Root exudates are the medium of material and signal exchange between plants and soil and are the key factors in the regulation of rhizosphere microecology. Rhizosphere microorganisms are an important part of the rhizosphere microecology of medicinal plants, and the interaction between root exudates and rhizosphere microorganisms has an important influence on the growth and quality formation of medicinal plants.

Tumor Associated Macrophages and TAMs-Based Anti-Tumor Nanomedicines.

As an important part of tumor microenvironment, tumor associated macrophages (TAMs) play a vital role in the occurrence, development, invasion, and metastasis of many malignant tumors and can significantly promote the formation of tumor blood vessels and lymphatic vessels, hence TAMs are greatly associated with poor prognosis. The research on nanomedicine has achieved huge progress, and nano-drugs have been widely utilized to treat various diseases through different mechanisms. Therefore, developing nano-drugs that are based on TAMs-associated anti-tumor mechanisms to effectively suppress tumor growth is expected to be a promising research filed.
