Functional characterization of sesquiterpene synthase in Mongolian medicine Syringa oblata in heartwood formation.

Lilac (Syringa oblata) is a well-known horticultural plant, and its aromatic heartwood is widely utilized in Traditional Mongolian Medicine for treating angina. However, limited research on the dynamic changes and mechanisms of aromatic substance formation during heartwood development hinders the analysis and utilization of its medicinal components. In this study, volatile metabolome analysis revealed that sesquiterpenes are the primary metabolites responsible for the aroma in heartwood, with cadinane and eremophilane types being the most prevalent.

Traditional Chinese medicine residues promote the growth and quality of Bunge by improving soil health under continuous monoculture.

Continuous monoculture of crops has resulted in reduced yields and quality, as well as soil deterioration. Although traditional Chinese medicine residues (TCMRs) are known to promote plant growth and soil health, few studies have investigated their effectiveness in continuous monoculture soils. Here, we studied the impact of chemical fertilizers (CF) and four TCMRs with antibacterial activities on the growth of (a widely used medicinal plant in China), accumulation of active ingredients in plants, and soil health under continuous monoculture conditions.

[Effects of temperature and humidity on infection of Fusarium oxysporum in seedlings of Salvia miltiorrhiza].

Wilt disease is a major disease of cultivated Salvia miltiorrhiza, which is caused by Fusarium oxysporum. Since the infection process of F. oxysporum in plants is affected by environment factors, this study was conducted to reveal the relationship between disease severity and concentration of the pathogen in plants in the infection process of F.

[Effects of interaction between ubiquitin/26S proteasome inhibitor MG132 and mycorrhiza on growth and effective components of Salvia miltiorrhiza].

Ubiquitin/26 S proteasome system(UPS) is one of the main ways to regulate the degradation of proteins in plants, and plays an important role in physiological processes such as secondary metabolism and plant hormone signal transduction. As indicated recently, UPS is involved in plant-microbe interactions, and presumably regulates arbuscular mycorrhizal symbiosis to affect its effects. This study investigated the effects of interaction between Cbz-leu-leu-leucinal(MG132) and the mycorrhiza on the growth and effective components of Salvia miltiorrhiza by inoculation with Glomus intraradices and spraying MG132 solution.

Arbuscular mycorrhizal fungi enhance disease resistance of to Fusarium wilt.

Bunge (Danshen in Chinese) is vulnerable to Fusarium wilt, which severely affects the quality of the crude drug. Mycorrhizal colonization enhances resistance to fungal pathogens in many plant species. In this study, pre-inoculation of with the arbuscular mycorrhizal fungi (AMF) significantly alleviated Fusarium wilt caused by .

[Pathogenicity and induced systemic resistance of Fusarium oxysporum and Verticillium dahlia to Salvia miltiorrhiza].

Salvia miltiorrhiza is a commonly used bulk medicinal material in China. Due to the increasing demand in recent years, the planting area is expanding. In the artificial cultivation of S.

Arbuscular mycorrhiza alters the nutritional requirements in Salvia miltiorrhiza and low nitrogen enhances the mycorrhizal efficiency.

Salvia miltiorrhiza Bunge (danshen in Chinese) is one of the most important medicinal cash crops in China. Previously, we showed that arbuscular mycorrhizal fungi (AMF) can promote S. miltiorrhiza growth and the accumulation of bioactive compounds.

Comparative Transcriptomics and Metabolites Analysis of Two Closely Related Species Reveal Environmental Adaptation Mechanism and Active Ingredients Difference.

Roots of and are recorded as the source plant of traditional Chinese medicine "Langdu," containing active ingredients with anticancer and anti-AIDS activity. However, the two species have specific patterns in the graphic distribution. Compared with distributes in higher latitude and lower temperature areas and might have experienced cold stress adaptation.

The ERF-VII transcription factor SmERF73 coordinately regulates tanshinone biosynthesis in response to stress elicitors in Salvia miltiorrhiza.

Here, we investigate the role of SmERF73, a group VII ETHYLENE RESPONSE FACTOR stress response transcription factor, in the regulation of post-modification of the skeleton precursors of diterpene tanshinones in Salvia miltiorrhiza. Most genes found to be involved in tanshinone biosynthesis are located on chromosome 6, and five of these genes comprise a large gene cluster in S. miltiorrhiza.

[Effect of different fungicides on efficiency of mycorrhizal symbiosis on Salvia miltiorrhiza].

Arbuscular mycorrhizal fungi provided is beneficial to Salvia miltiorrhiza for increasing yield, promoting the accumulation of active ingredients, and alleviating S. miltiorrhiza disease etc. However, the application of fungicides will affect the benefit of arbuscular mycorrhizal fungi and there is little research about it.

[Cloning and expression analysis of 5-phosphomevalonate kinase gene (CcPMK) in Cinnamomum camphora].

The 5-phosphomevalonate kinase(PMK) is a key enzyme in mevalonate(MVA) pathway which reversibly catalyzes the phosphorylation of mevalonate 5-phosphate(MVAP) to form mevalonate-5-diphosphate(MVAPP) in the presence of ATP and divalent metal ion such as Mg~(2+). In this research, on the basis of the transciptome database of Cinnamomum camphora, the PMK was cloned by cDNA from C. camphora, and was named CcPMK(GenBank number KU886266).

[Effect of soil pH on efficiency of mycorrhizal symbiosis on Salvia miltiorrhiza].

By comparing the effects of soil pH on the efficiency of mycorrhizal symbiosis on Salvia miltiorrhiza， the study is aimed to provide guidance for the use of mycorrhiza in the cultivation of S. miltiorrhiza. In this experiment, the inoculant treated and the non-inoculant treated control were grown in different soil pH.
