Article Synopsis
- Magnesium is crucial for plant health as it is a key part of chlorophyll and acts as a coenzyme, but its regulatory role in secondary metabolite synthesis is not fully understood.
- The study focuses on Sophora tonkinensis, a medicinal plant in China, analyzing how different magnesium concentrations in tissue-cultured seedlings affect their secondary metabolites and overall growth.
- By using multi-omics data analysis, the research reveals the complex ways magnesium influences metabolic pathways, which in turn affects the levels of beneficial compounds and the growth of the plant.
[Overview of research and development of polypeptide drugs and traditional Chinese medicine-peptides].

November 2022
Peptide is a compound consisting of 2-50 amino acids, which is intermediate between small molecule and protein. It is characterized by a variety of biological activities, easy absorption, strong specific targeting, and few side effects and has become one of the hotspots in biomedical research in recent years. Chinese medicine contains a large number of peptides.

[Effect of exogenous GA₃ and DPC on active components of Lonicera japonica and its mechanism].
Zhongguo Zhong Yao Za Zhi
December 2018
To reveal the effect of plant growth regulator GA₃ and DPC on the active components and its possible mechanism of Lonicera japonica. GA and DPC were applied at the stage of flower bud differentiation, and the content of active ingredients was measured by LC-MS-MS, the content of endogenous hormones were measured by ELISA, and the expression of key enzyme enes expression was determined by qRT-PCR. The level of endogenous hormone GA₃, IAA, ZR, DHZR and iPA in the GA treatment group was significantly improved, the expression of C4H1, C4H2, 4CL1 and HQT2 were also significantly increased.

May 2015
Article Synopsis
- The study analyzed genetic sequences of 9 Gynostemma species to understand their evolutionary relationships, using Hemsleya macrosperma as an outgroup.
- The analysis revealed that G. pentaphyllum var. pentaphyllum did not form a clear monophyletic group in the phylogenetic trees generated.
- There is uncertainty regarding whether G. longipes and G. laxum should be classified as separate species, and the study supports the current classification of subgenus units within Gynostemma.
[Analysis of critical genes expression of chlorogenic acid and luteolin biosyntheses in Lonicera confusa].
Zhongguo Zhong Yao Za Zhi
July 2014
This study analysed the tissue specific expression of critical genes involved in chlorogenic acid and luteolin biosynthesis, for exploiting the molecular mechanism of components biosynthesis in Lonicera confusa. Expression of PAL, 4CL, C4H, CHS, CHI, FNS and HQT gene families of chlorogenic acid and luteolin biosynthesis-related genes in buds and leaves of L. confusa were analyed by Real-time PCR.
