“…The effect of fertilizers can be specific to certain bacterial groups [84,85]. The type of fertilizer, whether organic or conventional, can favor the abundance of particular groups of microorganisms while affecting the abundance of others [86], as observed in our results. In the case of humus fertilization, the occurrence of bacterial OTUs increased compared to treatments fertilized with DAP.…”

Guadua angustifolia produces phenolic compounds, and this production may be influenced by the application of chemical, organic, and biological fertilizers. Currently, the effect of such fertilizers on the synthesis dynamics of this group of metabolites in bamboo is unknown. In this study, the total phenolic content (TPC) and total flavonoid content (TFC) in the leaves of plants fertilized with diammonium phosphate (DAP) and humus in combination with the biofertilizers Promofort®, Azospirillum brasilense, Pseudomonas fluorescens, and Stenotrophomonas sp. were determined using colorimetric techniques across three sampling events (four, five, and seven months after planting). Additionally, an approximation of the bacterial profile of G. angustifolia roots was performed using the DGGE-PCR fingerprint technique. Through repeated measures ANOVA (rmANOVA), it was determined that there is no statistically significant three-way interaction between humus or DAP application, biological fertilizers, and time for either TPC or TFC. However, there were interactions between the sampling event and the application of biological fertilizers for both TPC and TFC, with the latter being promoted by the application of Promofort®. Finally, NMDS analyses and heatmaps with hierarchical clustering showed that the composition and abundance of OTUs in the bacterial profile varied with fertilization type and increased over time.

“…This agrees with previous studies on grapevine microbiome research (Deyett and Rolshausen 2020;Liu et al 2022). Both soils were colonized mainly by Rubrobacter and Gemmatimonadaceae family, which are commonly found bacteria in grapevine soil rhizosphere core microbiome (Wang et al 2021). In sandy soil, plants also contain Vicinamibacterales family in high abundance that are typical of bacterial microbiomes present in soils with high content of sand (Costa et al 2021).…”

With a reduction on available chemical treatments, there is an increased interest on biological control of grapevine trunk diseases. Few studies have investigated the impact of introducing beneficial microorganisms in rhizosphere, on the indigenous soil existent microbiome. In this study, we explored the effect of two biological control agents, Trichoderma atroviride SC1 (commercial product Vintec® from Certis Belchim, Ta SC1) and Bacillus subtilis PTA-271 (Bs PTA-271), on the grapevine rhizosphere bacterial and fungal microbiome, and on plant defense expression, using High-Throughput Amplicon Sequencing and qPCR, respectively. Additionally, we quantified both Ta SC1 and Bs PTA-271 in rhizosphere overtime using digital droplet PCR. The fungal microbiome was more affected by factors such as soil type, BCA treatment, and sampling time than bacterial microbiome. Specifically, Ta SC1 application produced negative impacts on fungal diversity, while applications of BCAs did not affect bacterial diversity. Interestingly, the survival and establishment of both BCAs showed opposite trends depending on the soil type, indicating that the physicochemical properties of soils have a role on BCA establishment. Fungal co-occurrence networks were less complex than bacterial networks, but highly impacted by Ta SC1 application. Soils treated with Ta SC1, presented more complex and stable co-occurrence networks, with a higher number of positive correlations. Induced grapevine defenses also differed according to the soil, being more affected by BCA inoculation on sandy soil.

“…This suggests that Bathyarchaeia may play specific roles in regulating ecological functions in different soil environments. Some studies suggested that the improvement of soil fertility by organic fertilizer and soil regulator might decrease the relative abundance of the soil bacterium Steroidobacter ( Wang et al, 2021 ). Steroidobacter was significantly detected in intercropping group in this study and was negatively correlated with a variety of metabolites.…”

IntroductionMicroorganisms play an important role in the multifunctionality of soil ecosystems. Soil microbial diversity and functions have a great impact on plant growth and development. The interactions between tea trees and soil microbiota can be linked with planting patterns and management strategies, whose effects on soil microbial community structure and metabolites are still unclear.MethodsHere we used amplicon sequencing and metabolomic analysis to investigate the differences in soil microbial composition and metabolites among three tea production systems: organic, non-organic, and intercropping.ResultsWe detected significant differences among the three systems and found that Firmicutes, Proteobacteria, Acidobacteriota, Actinobacteriota and Chloroflexi were the main bacteria in the three soil groups, although they varied in relative abundance. Acidobacteria bacterium increased significantly in the organic and intercropping groups. For fungi, Ascomycota and Basidiomycota were the main differential fungal phyla. Fungi alpha-diversity in the non-organic group was significantly higher than that in the other two groups, and was correlated with multiple soil physical and chemical factors. Moreover, network analysis showed that bacteria and fungi were strongly correlated. The changes in soil microorganisms caused by management and planting patterns may affect soil quality through corresponding changes in metabolites. Metabolomic analysis showed differences in metabolite composition among different groups. It was also found that the arachidonic acid metabolic pathway was affected by changes in soil microorganisms, and may further affect soil quality in an essential manner.DiscussionPlanting patterns and management strategies may significantly affect soil microorganisms and therefore metabolites. Changes in soil microorganisms, especially in fungi, may alter soil quality by affecting soil physicochemical properties and metabolites. This study will provide new insights into soil quality monitoring from a microbiological perspective.
