Abstract Background Plants live with diverse microbial communities which profoundly affect multiple facets of host performance, but if and how development impacts the assembly, functions interactions crop microbiomes are poorly understood. Here we examined both bacterial fungal across soils, epiphytic endophytic niches leaf root, plastic fake plant (representing environment-originating microbes) at three developmental stages maize two contrasting sites, further explored potential function phylloplane based on metagenomics. Results Our results suggested that stage had a much stronger influence diversity, composition interkingdom networks in compartments than strongest effect phylloplane. Phylloplane were co-shaped by growth seasonal environmental factors, air (represented plants) as its important source. Further, found more strongly driven deterministic processes early similar pattern was for late stage.

The demand for nitrogen (N) crop production increased rapidly from the middle of twentieth century and is predicted to at least double by 2050 satisfy on-going improvements in productivity major food crops such as wheat, rice maize that underpin staple diet most world's population. will need be fulfilled two main sources N supply – biological (gas) (N2) fixation (BNF) fertilizer supplied through Haber-Bosch processes. BNF provides many functional benefits agroecosystems. It a vital mechanism replenishing reservoirs soil organic improving availability support growth while also assisting efforts lower negative environmental externalities than N. In cereal-based cropping systems, legumes symbiosis with rhizobia contribute largest input; however, diazotrophs involved non-symbiotic associations plants or present free-living N2-fixers are ubiquitous provide an additional source fixed This review presents current knowledge free-living, symbiotic global cycle, examines regional estimates contributions BNF, discusses possible strategies enhance prospective benefit cereal nutrition. We conclude considering challenges introducing planta into cereals reflect on potential both conventional alternative management systems encourage ecological intensification legume production.

Geographical, climatic, and soil factors control the altitudinal pattern of rhizosphere microbial diversity and its driving effect on root zone soil multifunctionality in mountain ecosystems

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 904, P. 166932 - 166932

Published: Sept. 9, 2023

Shifts in rhizosphere soil microorganisms of dominant plants' response to climate change profoundly impact mountain ecosystem multifunctionality; relatively little is known about the relationship between them and how they depend on long-term environmental drivers. Here, we conducted analyses microbial altitudinal pattern, community assembly, co-occurrence network 6 plants six typical vegetation zones ranging from 1350 2900 m (a.s.l.) Helan Mountains by absolute quantitative sequencing technology, finally related microbiomes root zone multifunctionality ('soil multifunctionality' hereafter), dependence was explored. It found that pattern bacterial fungal diversities differed significantly. Higher more potential interactions Stipa breviflora Carex coninux were at lowest highest altitudes. Bacterial α diversity, identity some taxa, had significant positive or negative effects multifunctionality. The effect sizes diversity greater than those effects. These results indicated balance microbes determines As number phylum level increases, there will be a net gain Our study reveals geographical climatic factors can directly modulate properties thereby affecting driving multifunctionality, points rather fungi being strongly associated with This work has important ecological implications for predicting multiple environment-plant-soil-microorganisms ecosystems respond future change.

Abstract Root-associated microbial communities have strong influences on the health and development of plants. Through secretion root exudates, soil microbiome is impacted by plants, thereby steering plant-soil reactions. Considering importance exudates in establishment symbiotic associations rhizosphere, it quite clear that understanding interaction between plant roots may prove beneficial. Here, we review soil.

Abstract Soil organisms are affected by the presence of predatory protists. However, it remains poorly understood how protists can affect plant disease incidence and fertilization regimes these interactions. Here, we characterise rhizosphere bacteria, fungi over eleven growing seasons tomato planting under three regimes, i.e conventional, organic bioorganic, with different bacterial wilt levels. We find that negatively associated incidence, especially two ciliophoran Colpoda OTUs, bioorganic enhances abundance In glasshouse experiments protist influences directly consuming pathogens indirectly increasing pathogen-suppressive microorganisms in soil. Together, demonstrate reduce plants via direct indirect reductions pathogens. Our study provides insights on role play disease, which could be used to design more sustainable agricultural practices.

Fertilization alters protistan consumers and parasites in crop‐associated microbiomes

Environmental Microbiology, Journal Year: 2021, Volume and Issue: 23(4), P. 2169 - 2183

Published: Jan. 6, 2021

Summary Crop plants carry an enormous diversity of microbiota that provide massive benefits to hosts. Protists, as the main microbial consumers and a pivotal driver biogeochemical cycling processes, remain largely understudied in plant microbiome. Here, we characterized composition protists sorghum leaf phyllosphere, rhizosphere bulk soils, collected from 8‐year field experiment with multiple fertilization regimes. Phyllosphere was important habitat for protists, dominated by Rhizaria, Alveolata Amoebozoa. Rhizosphere soils had significantly higher than protistan community structure differed among three plant–soil compartments. Fertilization altered specific functional groups parasites. Variation partitioning models revealed soil properties, bacteria fungi predicted significant proportion variation communities. Changes may turn alter compositions bacterial fungal communities top‐down control food webs. Altogether, novel evidence affects parasites crop‐associated microbiomes, which have implications potential changes their ecological functions under intensive agricultural managements.

Published: March 21, 2021

Abstract Microbial community circadian rhythms have a broad influence on host health and even though light-induced environmental fluctuations could regulate microbial communities, the contribution of light to rhizosphere communities has received little attention. To address this gap, we monitored diel changes in rice (Oryza sativa L.) soil under light–dark constant dark regimes, identifying microbes with caused by exposure clocks, respectively. While displayed taxa possessing two conditions were dissimilar. Light concealed clocks as regulatory driver, leading fewer ecological niches versus communities. These findings disentangle regulation mechanisms for highlight role
