“…The αdiversity of rhizobacteria in rhizosphere soils of cotton (Gossypium hirsutum L.) were also increased compared with bulk soils [58]. Meanwhile, we noticed that bacterial and fungal diversity increased and then decreased during P. notoginseng growth, which is similar to the observations in P. ginseng [59] and Pseudostellaria heterophylla [60]. These data reveal that succession characteristics of bacterial and fungal diversity are similar as the P. notoginseng grew.…”

Background: Rhizosphere microbiome play important roles in promoting plant growth. However, it is not well understood how rhizosphere microbiome were driven by medical plants during growth stages and whether they contribute the accumulation of medical values. Panax notoginseng is a perennial medicinal plant, which belowground biomass and saponin contents are the important indicators of its value. Here, we use high-throughput sequencing method to study the temporal dynamics of perennial P. notoginseng rhizosphere microbiomes and the relationship between the indicators and core rhizosphere microbiomes.Results: The results show that the diversity, composition and network structures of the bacterial and fungal communities are mainly driven by the developmental stages. And succession characteristics of bacterial and fungal diversity show similar parabolic patterns during the developmental stages. Enrichment and depletion of the bacterial and fungal communities are active at the 3-year root growth (3YR) stage. From samples collected at a large-spatial P. notoginseng production area at the 3YR stage, we obtained 639 bacterial and 310 fungal core operational taxonomic units (OTUs). Analysis of the data indicate that the microbiome diversity is related to the belowground biomass and total saponin contents. Some genera, such as Pseudomonas, Massilia, Sphingobium, and Phoma are positively correlated to the belowground biomass, and genera likely Staphylotrichum, Chaetosphaeria, and Podospora are positively correlated with total saponin contents. Additionally, we identified 36 microbial functions involving in plant-microbe and microbe-microbe interactions, nutrition acquisition, and disease resistance. They are related to belowground biomass and saponin contents. Conclusions: In short, this study provides a detailed and systematic survey of rhizosphere microbiome in P. notoginseng and reveals that P. notoginseng rhizosphere microbiomes are largely driven by the developmental stages, while the core microbiomes are related to the belowground biomass and saponins contents of the plant. The finding may enhance our understanding of the interaction between microbes and perennial plants and improve our ability to manage root microbiota for sustainable production of the herb medicine.

“…Soil microorganisms not only have mutual effects on each other but also interact with the surrounding environment. Mounting evidence indicates that root exudates initiate and modulate the dialogue between the plant and soil microbes, composed of both pathogenic and beneficial microbes 34 . With the replanting of apple trees, the characteristics of rhizosphere soil changes, causing shifts in the characteristics of root exudates due to apple physiological changes.…”

Bohai Gulf is the main area for apple tree cultivation in China. Consecutive replanting significantly affects the yield and quality of apple trees in this area. Microecological imbalance in apple trees’ rhizospheres caused by variation in the soil microbial community is considered the primary cause of apple replant disease (ARD). This study analysed the microbial communities of the rhizospheres of perennial apple trees (PAT) and apple tree saplings under replanting (ATS) around Bohai Gulf using high-throughput sequencing. The results revealed increased populations of typical pathogenic fungi Verticillium and bacteria Xanthomonadaceae, and decreased populations of beneficial bacterial populations Pseudomonas and Bacillus with replanting, suggesting that competition between pathogens and beneficial microbes varies according to the ratio of pathogens to beneficial microbes in rhizosphere soil under the replanting system. Meanwhile, replanting was accompanied by an increase in the antagonistic bacteria Arthrobacter and fungus Chaetomium, suggesting that increased numbers of pathogens can lead to more instances of antagonism. Redundancy analysis (RDA) revealed site position and the main soil properties (pH, organic matter, available N, available K, available P, and moisture) affected the microbial community composition. It found clear differences in soil microbial communities and demonstrated a better understanding of the causes for ARD.

“…This feedback inhibits beneficial microbes but promotes parasites and pathogen outbreaks, and in turn results in autotoxicity or soil sickness, and the hindrance of plant growth and development, which reduces plant yield and quality [ 8 , 9 , 10 ]. Autotoxicity and soil sickness are the typical results of negative plant–soil interactions, mainly driven by agricultural landscape simplification, such as continuous monoculture which is the cropping of the same plant in the same field for many consecutive years [ 11 , 12 , 13 , 14 ]. Production of autotoxins, soil nutrient imbalance, and the alteration of soil-associated microbial community composition are considered as fundamental issues related to autotoxicity and soil sickness [ 15 , 16 ].…”

Positive plant–soil feedback depends on beneficial interactions between roots and microbes for nutrient acquisition; growth promotion; and disease suppression. Recent pyrosequencing approaches have provided insight into the rhizosphere bacterial communities in various cropping systems. However; there is a scarcity of information about the influence of root exudates on the composition of root-associated bacterial communities in ratooning tea monocropping systems of different ages. In Southeastern China; tea cropping systems provide the unique natural experimental environment to compare the distribution of bacterial communities in different rhizo-compartments. High performance liquid chromatography–electrospray ionization–mass spectrometry (HPLC–ESI–MS) was performed to identify and quantify the allelochemicals in root exudates. A high-throughput sequence was used to determine the structural dynamics of the root-associated bacterial communities. Although soil physiochemical properties showed no significant differences in nutrients; long-term tea cultivation resulted in the accumulation of catechin-containing compounds in the rhizosphere and a lowering of pH. Moreover; distinct distribution patterns of bacterial taxa were observed in all three rhizo-compartments of two-year and 30-year monoculture tea; mediated strongly by soil pH and catechin-containing compounds. These results will help to explore the reasons why soil quality and fertility are disturbed in continuous ratooning tea monocropping systems; and to clarify the associated problems.
