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.

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.

Developing climate‐resilient crops: improving plant tolerance to stress combination

The Plant Journal, Год журнала: 2021, Номер 109(2), С. 373 - 389

Опубликована: Сен. 5, 2021

SUMMARY Global warming and climate change are driving an alarming increase in the frequency intensity of different abiotic stresses, such as droughts, heat waves, cold snaps, flooding, negatively affecting crop yields causing food shortages. Climate is also altering composition behavior insect pathogen populations adding to yield losses worldwide. Additional constraints agriculture caused by increasing amounts human‐generated pollutants, well negative impact on soil microbiomes. Although laboratory, we trained study individual stress conditions plants, field many pests could simultaneously or sequentially affect combination. Because expected combination events (e.g., waves combined with drought, other and/or pathogens), a concentrated effort needed how crops. This need particularly critical, studies have shown that response plants unique cannot be predicted from simply studying each stresses part Strategies enhance tolerance particular may therefore fail this specific stress, when factors. Here review recent combinations propose new approaches avenues for development combination‐ change‐resilient

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.

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

Summary Harnessing plant‐associated microbiomes offers an invaluable strategy to help agricultural production become more sustainable while also meeting growing demands for food, feed and fiber. A plethora of interconnected interactions among the host, environment microbes, occurring both above below ground, drive recognition, recruitment colonization resulting in activation downstream host responses functionality. Dissecting these complex by integrating multiomic approaches, high‐throughput culturing, computational synthetic biology advances is providing deeper understanding structure function native microbial communities. Such insights are paving way towards development products as well engineered with communities capable delivering agronomic solutions. While there a market microbial‐based solutions improve crop productivity, challenges commercialization remain. The continued translation microbiome knowledge into real‐world scenarios will require concerted transdisciplinary research, cross‐training next generation scientists, targeted educational efforts prime growers general public successful adoption innovative technologies.

Microbiological tools, biofertilizers, and biocontrol agents, which are bacteria fungi capable of providing beneficial outcomes in crop plant growth health, have been developed for several decades. Currently we a selection strains available as products agriculture, predominantly based on plant-growth-promoting rhizobacteria (PGPR), soil, epiphytic, mycorrhizal fungi, each having specific challenges their production use, with the main one being inconsistency field performance. With growing global concern about pollution, greenhouse gas accumulation, increased need plant-based foods, demand biofertilizers agents is expected to grow. What prospects finding solutions existing tools? The inconsistent performance could be overcome by using combinations different types microbial strains, consisting various members full microbiome. However, thorough understanding microbiological tool, communities, mechanisms action must precede product development. In this review, offer brief overview tools consider techniques approaches that can produce information new traits biofertilizer strains. We also discuss innovative ideas how where identify efficient strain family.
