Plant roots nurture a tremendous diversity of microbes via exudation photosynthetically fixed carbon sources. In turn, probiotic members the root microbiome promote plant growth and protect host against pathogens pests. Arabidopsis thaliana-Pseudomonas simiae WCS417 model system root-specific transcription factor MYB72 MYB72-controlled β-glucosidase BGLU42 emerged as important regulators beneficial rhizobacteria-induced systemic resistance (ISR) iron-uptake responses. regulates biosynthesis iron-mobilizing fluorescent phenolic compounds, after which activity is required for their excretion into rhizosphere. Metabolite fingerprinting revealed antimicrobial coumarin scopoletin dominant metabolite that produced in excreted rhizosphere MYB72- BGLU42-dependent manner.

Ecology and Evolution of Plant Microbiomes

Annual Review of Microbiology, Год журнала: 2019, Номер 73(1), С. 69 - 88

Опубликована: Май 15, 2019

Microorganisms colonizing plant surfaces and internal tissues provide a number of life-support functions for their host. Despite increasing recognition the vast functional capabilities microbiome, our understanding ecology evolution taxonomically hyperdiverse microbial communities is limited. Here, we review current knowledge genotypic phenotypic traits as well allogenic autogenic factors that shape microbiome composition functions. We give specific emphasis to impact domestication on assembly how insights into microbiomes wild relatives native habitats can contribute reinstate or enrich microorganisms with beneficial effects growth, development, health. Finally, introduce new concepts perspectives in research, particular community theory mechanistic framework unravel interplay distinct ecological processes-i.e., selection, dispersal, drift, diversification-that structure microbiome.

Root exudates drive the soil-borne legacy of aboveground pathogen infection

Microbiome, Год журнала: 2018, Номер 6(1)

Опубликована: Сен. 12, 2018

Plants are capable of building up beneficial rhizosphere communities as is evidenced by disease-suppressive soils. However, it not known how and why soil bacterial impacted plant exposure to foliar pathogens if such responses might improve performance in the presence pathogen. Here, we conditioned growing multiple generations (five) Arabidopsis thaliana inoculated aboveground with Pseudomonas syringae pv tomato (Pst) same soil. We then examined a subsequent generation (sixth) grown pathogen-conditioned versus control-conditioned Moreover, assessed role altered root exudation profiles shaping microbiome infected plants.Plants showed increased levels jasmonic acid improved disease resistance. Illumina Miseq 16S rRNA gene tag sequencing revealed that both bulk were Pst infection. Infected plants exhibited significantly higher amino acids, nucleotides, long-chain organic acids (LCOAs) (C > 6) lower for sugars, alcohols, short-chain (SCOAs) ≤ 6). Interestingly, addition exogenous LCOA also elicited response.Collectively, our data suggest can recruit via modification patterns response benefit generations.

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.

Linking Plant Secondary Metabolites and Plant Microbiomes: A Review

Frontiers in Plant Science, Год журнала: 2021, Номер 12

Опубликована: Март 2, 2021

Plant secondary metabolites (PSMs) play many roles including defense against pathogens, pests, and herbivores; response to environmental stresses, mediating organismal interactions. Similarly, plant microbiomes participate in of the above-mentioned processes directly or indirectly by regulating metabolism. Studies have shown that plants can influence their microbiome secreting various and, turn, may also impact metabolome host plant. However, not much is known about communications between interacting partners phenotypic changes. In this article, we review patterns potential underlying mechanisms interactions PSMs microbiomes. We describe recent developments analytical approaches methods field. The applications these new increased our understanding relationships Though current studies primarily focused on model organisms, results obtained so far should help future agriculturally important facilitate development manipulate PSMs–microbiome with predictive outcomes for sustainable crop productions.

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

Plant health: feedback effect of root exudates-rhizobiome interactions

Applied Microbiology and Biotechnology, Год журнала: 2018, Номер 103(3), С. 1155 - 1166

Опубликована: Дек. 20, 2018

The well-being of the microbial community that densely populates rhizosphere is aided by a plant's root exudates. Maintaining health key factor in its continued existence. As minute as rhizospheric microbes are, their importance plant growth cannot be overemphasized. They depend on plants for nutrients and other necessary requirements. relationship between rhizosphere-microbiome (rhizobiome) hosts can beneficial, non-effectual, or pathogenic depending involved. This relationship, to large extent, determines fate host survival. Modern molecular techniques have been used unravel rhizobiome species' composition, but interplay exudates factors maintenance healthy not yet thoroughly investigated. Many functional proteins are activated upon contact with external factors. These may elicit promoting suppressing responses from plants. To optimize productivity plants, diversity modulatory need clearly understood improved health.
