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. Moreover, taxa played role network yield prediction stage, while did so Metagenomic analyses indicated possessed higher functional diversity genes related to nutrient provision enriched N assimilation C degradation Coincidently, abundant beneficial like Actinobacteria, Burkholderiaceae Rhizobiaceae observed saprophytic fungi Conclusions suggest influences microbiome assembly functions, take differentiated ecological different development. This study provides empirical evidence exerting strong selection during These findings have implications future tools manipulate sustainable increase primary productivity.

Trophic Interactions and the Drivers of Microbial Community Assembly

Current Biology, Год журнала: 2020, Номер 30(19), С. R1176 - R1188

Опубликована: Окт. 1, 2020

Despite numerous surveys of gene and species content in heterotrophic microbial communities, such as those found animal guts, oceans, or soils, it is still unclear whether there are generalizable biological ecological processes that control their dynamics function. Here, we review experimental theoretical advances to argue networks trophic interactions, which the metabolic excretions one primary resource for another, constitute central drivers community assembly. Trophic interactions emerge from deconstruction complex forms organic matter into a wealth smaller intermediates, some released environment serve nutritional buffet community. The structure emergent network rate at resources supplied many features assembly, including relative contributions competition cooperation emergence alternative states. Viewing assembly through lens also has important implications spatial communities well functional redundancy taxonomic groups. Given ubiquity across environments, they impart common logic can enable development more quantitative predictive ecology.

Rhizosphere protists are key determinants of plant health

Microbiome, Год журнала: 2020, Номер 8(1)

Опубликована: Март 3, 2020

Abstract Background Plant health is intimately influenced by the rhizosphere microbiome, a complex assembly of organisms that changes markedly across plant growth. However, most microbiome research has focused on fractions this particularly bacteria and fungi. It remains unknown how other microbial components, especially key predators—protists—are linked to health. Here, we investigated holistic including bacteria, eukaryotes (fungi protists), as well functional metabolism genes. We these communities genes throughout growth tomato plants either developed disease symptoms or remained healthy under field conditions. Results found pathogen dynamics best predicted protists. More specifically, microbial-feeding phagotrophic protists differed between later diseased at establishment. The relative abundance phagotrophs negatively correlated with growth, suggesting predator-prey interactions influence performance. Furthermore, likely shifted bacterial functioning enhancing pathogen-suppressing secondary metabolite involved in mitigating success. Conclusions illustrate importance top-down controllers propose perspective, protists, provides optimal next step predicting
