Host selection shapes crop microbiome assembly and network complexity

New Phytologist, Год журнала: 2020, Номер 229(2), С. 1091 - 1104

Plant microbiomes are essential to host health and productivity but the ecological processes that govern crop microbiome assembly not fully known. Here we examined bacterial communities across 684 samples from soils (rhizosphere bulk soil) multiple compartment niches (rhizoplane, root endosphere, phylloplane, leaf endosphere) in maize (Zea mays)-wheat (Triticum aestivum)/barley (Hordeum vulgare) rotation system under different fertilization practices at two contrasting sites. Our results demonstrate along soil-plant continuum is shaped predominantly by niche species rather than site or practice. From epiphytes endophytes, selection pressure sequentially increased diversity network complexity consequently reduced, with strongest effect endosphere. Source tracking indicates mainly derived gradually enriched filtered plant niches. Moreover, were dominated a few dominant taxa (c. 0.5% of phylotypes), bacilli identified as important biomarker for wheat barley Methylobacteriaceae maize. work provides comprehensive empirical evidence on selection, potential sources enrichment assembly, has implications future management manipulation sustainable agriculture.

Modulation of the Root Microbiome by Plant Molecules: The Basis for Targeted Disease Suppression and Plant Growth Promotion

Frontiers in Plant Science, Год журнала: 2020, Номер 10

Опубликована: Янв. 24, 2020

Plants host a mesmerizing diversity of microbes inside and around their roots, known as the microbiome. The microbiome is composed mostly fungi, bacteria, oomycetes, archaea that can be either pathogenic or beneficial for plant health fitness. To grow healthy, plants need to surveil soil niches roots detection microbes, in parallel maximize services nutrients uptake growth promotion. employ palette mechanisms modulate including structural modifications, exudation secondary metabolites coordinated action different defence responses. Here, we review current understanding on composition activity root how molecules shape structure root-associated microbial communities. Examples are given interactions occur rhizosphere between soilborne fungi. We also present some well-established examples harnessing highlight fitness by selecting Understanding manipulate aid design next-generation inoculants targeted disease suppression enhanced growth.

Soil microbiota as game-changers in restoration of degraded lands

Science, Год журнала: 2022, Номер 375(6584)

Опубликована: Март 3, 2022

Land degradation reduces soil functioning and, consequently, the services that provides. Soil hydrological functions are critical to combat and promote restoration. microorganisms affect hydrology, but role of microbiota in forming sustaining is not well explored. Case studies indicate potential as game-changers restoring functions. We review state art microorganism use land restoration technology, groups with greatest for restoration, knowledge effect on physical properties, proposed strategies long-term degraded lands. also emphasize need advance emerging research field biophysical landscape interactions support soil-plant ecosystem practices.

The structure and function of the global citrus rhizosphere microbiome

Nature Communications, Год журнала: 2018, Номер 9(1)

Опубликована: Ноя. 14, 2018

Citrus is a globally important, perennial fruit crop whose rhizosphere microbiome thought to play an important role in promoting citrus growth and health. Here, we report comprehensive analysis of the structural functional composition microbiome. We use both amplicon deep shotgun metagenomic sequencing bulk soil samples collected across distinct biogeographical regions from six continents. Predominant taxa include Proteobacteria, Actinobacteria, Acidobacteria Bacteroidetes. The core comprises Pseudomonas, Agrobacterium, Cupriavidus, Bradyrhizobium, Rhizobium, Mesorhizobium, Burkholderia, Cellvibrio, Sphingomonas, Variovorax Paraburkholderia, some which are potential plant beneficial microbes. also identify over-represented microbial traits mediating plant-microbe microbe-microbe interactions, nutrition acquisition promotion rhizosphere. results provide valuable information guide isolation culturing and, potentially, harness power improve production

In the recent years, holobiont concept has emerged as a theoretical and experimental framework to study interactions between hosts their associated microbial communities in all types of ecosystems. The spread this many branches biology results from fairly realization ubiquitous nature host-associated microbes central role host biology, ecology, evolution. Through special series "Host-microbiota interactions: theory analysis," we wanted promote field research which considerable implications for human health, food production, ecosystem protection. preface, highlight collection articles selected issue that show, use, or debate approach taxonomically ecologically diverse organisms, humans plants sponges insects. We also identify some methodological challenges propose directions future on holobionts.

Disease-induced changes in plant microbiome assembly and functional adaptation

Microbiome, Год журнала: 2021, Номер 9(1)

Опубликована: Сен. 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. On hand, metagenomic significant enrichment several functional genes involved detoxification, biofilm formation, plant-microbiome signaling pathways (i.e., chemotaxis) plants.Together, demonstrate a could bacteria mitigate changes organ facilitate or its offspring survival. may attract through modulation pathways. These findings significantly advance our understanding interactions provide important harnessing sustainable agriculture. Video abstract.
