“…1 and 2). This is consistent with the previous report (Zheng et al, 2021b) that even in eld grown wheat from different locations with large geographic distance, the compartment niche still has the greatest impact on root-associated microbial community.…”

“…It is worth noting that the contribution of growth stage to prokaryotic community variation was highest in endosphere, followed by rhizosphere, then by bulk soil, indicating that host growth selection gradually weakened from endosphere to bulk soil. Although previous study has shown that the growth stage has little effect on prokaryotic communities of bulk soil in the wheat eld (Zheng et al, 2021b), this work found that the prokaryotic communities of the bulk soil changed with growth stage, possibly because the regular nutrient input altered soil properties.…”

“…In agroecosystems and natural habitats, biotic and abiotic in uences can overwhelm, amplify or mask the in uence of host genes (Wagner et al, 2016). Compared to previous studies (Zheng et al, 2021b), this study was conducted in a controlled environment which eliminated the complex natural exogenous stimuli driving the phenotype, thus, more realistically re ected the impacts of different factors on wheat root microbiome.…”

“…Previous studies showed that compartment niche, growth stage, variety, and nutrient input all affect the root microbial community assembly of wheat. Zheng et al investigated the eld samples including 5 wheat varieties from 4 locations, and con rmed that wheat root-associated prokaryotic community assembly is shaped predominantly by sample type, and signi cant interactive effects occur among wheat variety, location and growth stage on prokaryotic community assembly (Zheng et al, 2021b). Chen et al investigated the compositions of bacterial communities in the roots and rhizosphere of wheat under four levels of long-term inorganic nitrogen (N) fertilization at the tillering, jointing and ripening stages.…”

Background Wheat root-associated microbes play an indispensable role in helping plants obtain phosphorus (P) from soil. However, it is not clear how the effects of soil P on microorganisms vary with growth stage and variety. Therefore, revealing the interactive effects of soil P content, growth stage and variety on wheat root-associated microorganisms, which is important for further improving the P absorption strategy of plants. Methods Three wheat varieties were selected for pot experiment under three levels of soil P content, and sampling at seedling, flowering and mature stage, respectively. Using 16S rRNA gene profiling, we investigated the relative contribution of compartment niche, growth stage, variety and soil P content and their interaction effects on wheat root-associated prokaryotic communities. Results Wheat root-associated prokaryotic community assembly was mainly shaped by compartment niches. For each compartment niche, growth stage had higher contribution to the variations of prokaryotic communities than soil P content and wheat variety. The effects of P content on the prokaryotic communities varied by growth stage and variety. Meanwhile, the effects of wheat variety were also influenced by growth stage and soil P content. It is worth mentioning that low P content exacerbated the variation of prokaryotic communities among varieties. Conclusions This study revealed the interaction of host selection and soil P content on root-associated prokaryotic communities. The effects of soil P on wheat root-associated prokaryotic communities are dependent on P content, growth stage and variety. Our study provides a fundamental understanding on the relationship between soil P content and microorganisms.

“…For example, the effect of maize on the rhizosphere microbial community varies depending on the location of the plant 21 . In addition, plants such as wheat 22 , tobacco 23 and tomato 24 exhibit the same situation. It has also been shown that bacterial wilt resistant and susceptible plants have different rhizosphere bacterial communities.…”

Tobacco bacterial wilt has seriously affected tobacco production. Ethyl methanesulfonate (EMS) induced tobacco bacterial wilt resistant mutants are important for the control of tobacco bacterial wilt. High-throughput sequencing technology was used to study the rhizosphere bacterial community assemblages of bacterial wilt resistant mutant tobacco rhizosphere soil (namely KS), bacterial wilt susceptible tobacco rhizosphere soil (namely GS) and bulk soil (namely BS) in Xuancheng, Huanxi, Yibin and Luzhou. Alpha analysis showed that the bacterial community diversity and richness of KS and GS in the four regions were not significantly different. However, analysis of intergroup variation in the top 15 bacterial communities in terms of abundance showed that the bacterial communities of KS and GS were significantly different from BS, respectively. In addition, pH, alkali-hydrolysable nitrogen (AN) and soil organic carbon (SOC) were positively correlated with the bacterial community of KS and negatively correlated with GS in the other three regions except Huanxi. Network analysis showed that the three soils in the four regions did not show a consistent pattern of network complexity. PICRUSt functional prediction analysis showed that the COG functions were similar in all samples. All colonies were involved in RNA processing and modification, chromatin structure and dynamics, etc. In conclusion, our experiments showed that rhizosphere bacterial communities of tobacco in different regions have different compositional patterns, which are strongly related to soil factors.

Wheat (Triticum aestivum L.) root‐associated microbes play an indispensable role in helping plants obtain phosphorus (P) from soil. However, the relationships among soil P content, wheat root‐associated microorganisms and plants are still not fully understood. Therefore, revealing the effects of soil P content on the root‐associated microbes in different crop varieties at different growth stages is important for plant nutrient management. In this study, the variations of prokaryotic communities were investigated in the endosphere and rhizosphere of three wheat varieties growing in soils with different P content and at different growth stages. The key findings indicated that compartment niche and growth stage were the primary factors to shape wheat root‐associated prokaryotic community assembly under different soil P content. Soil P content mainly affected the prokaryotic community in rhizosphere rather than in endosphere. The effects of soil P content on root‐associated prokaryotic communities in different wheat varieties were different, and varied with the growth stage. Under low P treatment, there was greater variation in prokaryotic communities among varieties. In addition, compared with that in P‐deficient soil, wheat rhizosphere enriched more taxa and functions related to plant growth in the P‐sufficient soil. P‐efficient variety (ZGC) enriched more genera that positively related to plant growth in P‐sufficient soil. This study comprehensively revealed the influences of soil P content on wheat root‐associated prokaryotic communities, and the relationships among soil P content, wheat root‐associated prokaryotic community and plant.This article is protected by copyright.
