“…In addition, Yamazaki et al also pointed out that bacterial communities in rhizosphere environments differ from those in bulk soils through a multi-omics analysis (microbiome and transcriptome) of soybean plants in a field at Tokyo University of Agriculture and Technology, Japan (Yamazaki et al, 2021). However, most studies have focused on studying the effects of rhizocompartment on bacterial communities without considering the effects of plant life cycles and the interaction between the two on soil bacterial communities (Lucas et al, 2018;Yin and Yan, 2020;Li B. et al, 2022). Deterministic processes based on ecological niches and neutral stochastic processes are two processes that explain the changes in microbial community assembly, which may be influenced by the external environment (Beck et al, 2015;Zhou and Ning, 2017).…”

IntroductionDeep insights into adhering soil of root zones (rhizosphere and rhizoplane) microbial community could provide a better understanding of the plant-microbe relationship. To better understand the dynamics of these microbial assemblies over the plant life cycle in rhizodeposition along rice roots.MethodsHere, we investigated bacterial distribution in bulk, rhizosphere, and rhizoplane soils at tillering, heading, and mature stage, from rice (Oryza sativa) fields of the Northeast China.Results and DiscussionOur results revealed that soil bacterial α-diversity and community composition were significantly affected by root compartment niches but not by temporal change. Compared to rhizoplane soils in the same period, bulk in the heading and rhizosphere in the mature had the largest increase in Shannon’s index, with 11.02 and 14.49% increases, respectively. Proteobacteria, Chloroflexi, Bacteroidetes, and Acidobacteria are predominant across all soil samples, bulk soil had more phyla increased across the growing season than that of root related-compartments. Deterministic mechanisms had a stronger impact on the bacterial community in the compartments connected to the roots, with the relative importance of the bulk soil, rhizoplane and rhizosphere at 83, 100, and 56%, respectively. Because of ecological niche drivers, the bacterial networks in bulk soils exhibit more complex networks than rhizosphere and rhizoplane soils, reflected by more nodes, edges, and connections. More module hub and connector were observed in bulk (6) and rhizoplane (5) networks than in rhizosphere (2). We also detected shifts from bulk to rhizoplane soils in some functional guilds of bacteria, which changed from sulfur and nitrogen utilization to more carbon and iron cycling processes. Taken together, our results suggest distinct bacterial network structure and distribution patterns among rhizosphere, rhizoplane, and bulk soils, which could possibly result in potential functional differentiation. And the potential functional differentiation may be influenced by plant root secretions, which still needs to be further explored.

This study aimed to explore the important role of the rhizosphere microbiome in the quality of Atractylodes lancea (Thunb.) DC. (A. lancea). The rhizosphere microbial community of A. lancea at two sampling sites was studied using metagenomic technology. The results of α-diversity analysis showed that the rhizosphere microbial richness and diversity were higher in the Maoshan area. The higher abundance of core microorganisms of the rhizosphere, especially Penicillium and Streptomyces, in the Maoshan area compared with those in the Yingshan area might be an important factor affecting the yield of A. lancea. Redundancy analysis illustrated that the available phosphorus had a significant effect on the rhizosphere microbial community structure of A. lancea. We also showed that the plant–microbe and microbe–microbe interactions were closer in the Maoshan area than in the Yingshan area, and Streptomyces were the main contributors to the potential functional difference between the two regions. A. lancea in the Maoshan area had a high content of atractylodin and atractylon, which might be related to the enhanced abundance of Streptomyces, Candidatus-Solibacter, and Frankia. Taken together, this study provided theoretical insights into the interaction between medicinal plants and the rhizosphere microbiome and provides a valuable reference for studying beneficial microbes of A. lancea.

Introduction: Traditional Chinese medicine is an ancient system of wellness and health that has been used in almost all countries of the world, specially in Asia for thousands of years. Method: The growth, development, final yield and chemical compounds of medicinal plants can be negatively influenced by different kinds of biotic and abiotic stresses. Abiotic stress signals are chemical stress (Mineral salts, heavy metal, aerosols, gaseous toxins, pesticides, and pollutants), salinity (salt), temperature (Heat, cold), radiation (Ionisation radiation, light and UV), water (Flooding, drought) and mechanical stress (Submergence, wind, soil movement). Relevant literature has been obtained using the keywords “Traditional Chinese Medicine”, “Abiotic Stress”, “Biotic Stress”, “Ginseng”, “Ginger”, “Goji berry”, “Astragalus”, “Ginkgo”, “Artemisia annua L.”, “LC-MS”, “GC-MS”, and “NMR” in scientific information, namely “Web of Science”, “PubMed”, “SciFinder”, and “Elsevier”. Some of the plants’ secondary metabolites under different growth conditions are Camptothecin (Camptotheca acuminata), Capsaicin (Capsicum sp.), Rosmarinic acid (Salvia miltiorrhiza), Codeine (Papaver somniferum), Resveratrol (Grapes, groundnut), Artemisinin (Artemesia annua), Allicin (Allium sativum), Rohitukine (Dysoxylum binectariferum), Stevioside (Stevia rebaudiana), Andrographolide (Andrographis paniculata), Saikosaponins (Bupleurum chinense), Sennosides (Cassia augustifolia), Rutin (Dimorphandra mollis), Valepotriates (Valeria species), Indole alkaloids (Catharanthus roseous), and Furanocoumarins (Bituminaria bituminosa). Result: The aim of this article is a survey of active chemical compounds and metabolic changes of some of the most important medicinal plants in traditional Chinese medicine (TCM) in both abiotic and biotic stresses. Conclusion: Future research is needed to evaluate the effects of biotic and abiotic stresses on chemical compounds and active metabolites of medicinal plants specially traditional Chinese medicine, and more surveys on the roles of LC-MS, GC-MS and NMR techniques for a better understanding of chemical components of medicinal plants.
