Published: Sept. 15, 2021

The plant microbiome is an integral part of the host and increasingly recognized as playing fundamental roles in growth health. Increasing evidence indicates that rhizosphere recruits beneficial microbes to suppress soil-borne pathogens. However, ecological processes govern assembly functions below- aboveground compartments under pathogen invasion are not fully understood. Here, we studied bacterial fungal communities associated with 12 (e.g., soils, roots, stems, fruits) chili pepper (Capsicum annuum L.) using amplicons (16S ITS) metagenomics approaches at main production sites China investigated how Fusarium wilt disease (FWD) affects assembly, co-occurrence patterns, plant-associated microbiomes.The amplicon data analyses revealed FWD affected less on reproductive organs (fruit) than vegetative (root stem), strongest impact upper stem epidermis. Fungal intra-kingdom networks were stable their more sensitive communities. analysis microbial interkingdom network further indicated destabilized induced importance taxa. Although diseased plants susceptible colonization by other pathogenic fungi, can also recruit potential bacteria. Some taxa enriched identified core for microbiomes hub networks.

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.

The root microbiome refers to the community of microbes living in association with a plant's roots, and includes mutualists, pathogens, commensals. Here we focus on recent advances study commensal which is major research object microbiome-related researches. With rapid development new technologies, plant-commensal interactions can be explored unprecedented breadth depth. Both soil environment host plant drive assembly. bulk seed bank potential commensals, plants use exudates immune responses build healthy microbial communities from available microbes. extends functional system by participating variety processes, including nutrient absorption, growth promotion, resistance biotic abiotic stresses.

Rare taxa maintain the stability of crop mycobiomes and ecosystem functions

Environmental Microbiology, Journal Year: 2020, Volume and Issue: 23(4), P. 1907 - 1924

Published: Sept. 30, 2020

Plants harbour highly diverse mycobiomes which sustain essential functions for host health and productivity. However, ecological processes that govern the plant-mycobiome assembly, interactions their impact on ecosystem remain poorly known. Here we characterized role community assembly of both abundant rare fungal taxa along soil-plant continuums (rhizosphere, phyllosphere endosphere) in maize-wheat/barley rotation system under different fertilization practices at two contrasting sites. Our results indicate mycobiome is shaped predominantly by compartment niche species rather than environmental factors. Moreover, crop-associated communities are dominated few mainly belonging to Sordariomycetes Dothideomycetes, while majority diversity within represented taxa. For plant compartments, sub-community determined stochastic processes. In contrast, more sensitive selection governed deterministic Furthermore, our demonstrate play an important co-occurrence network functioning like crop yield soil enzyme activities. These significantly advance understanding highlight key sustaining stability functions.
