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.

Rhizosphere microbiome mediates systemic root metabolite exudation by root-to-root signaling

Proceedings of the National Academy of Sciences, Год журнала: 2020, Номер 117(7), С. 3874 - 3883

Опубликована: Фев. 3, 2020

Microbial communities associated with roots confer specific functions to their hosts, thereby modulating plant growth, health, and productivity. Yet, seminal questions remain largely unaddressed including whether how the rhizosphere microbiome modulates root metabolism exudation and, consequently, plants fine tune this complex belowground web of interactions. Here we show that, through a process termed systemically induced metabolites (SIREM), different microbial induce systemic changes in tomato exudation. For instance, acylsugars secondary is triggered by local colonization bacteria affiliated genus Bacillus Moreover, both leaf metabolomes transcriptomes change according community structure. Analysis metabolome points glycosylated azelaic acid as potential microbiome-induced signaling molecule that subsequently exuded free acid. Our results demonstrate assembly drives SIREM at molecular chemical levels. It highlights thus-far unexplored long-distance phenomenon may regulate soil conditioning.

Rhizosphere Microbiome Assembly and Its Impact on Plant Growth

Journal of Agricultural and Food Chemistry, Год журнала: 2020, Номер 68(18), С. 5024 - 5038

Опубликована: Апрель 7, 2020

Microorganisms colonizing the plant rhizosphere provide a number of beneficial functions for their host. Although an increasing investigations clarified great functional capabilities microbial communities, understanding precise mechanisms underlying impact microbiome assemblies is still limited. Also, not much known about various microbiome. In this review, we summarize current knowledge biotic and abiotic factors that shape as well traits are to plants growth disease-resistance. We give particular emphasis on root metabolites how contributes growth, yield, Finally, introduce new perspective novel method showing synthetic community construction provides effective approach unravel plant–microbes microbes–microbes interplays.

The Plant Microbiome: From Ecology to Reductionism and Beyond

Annual Review of Microbiology, Год журнала: 2020, Номер 74(1), С. 81 - 100

Опубликована: Июнь 12, 2020

Methodological advances over the past two decades have propelled plant microbiome research, allowing field to comprehensively test ideas proposed a century ago and generate many new hypotheses. Studying distribution of microbial taxa genes across habitats has revealed importance various ecological evolutionary forces shaping microbiota. In particular, selection imposed by strongly shapes diversity composition microbiota leads adaptation associated with navigating immune system utilizing plant-derived resources. Reductionist approaches demonstrated that interaction between immunity is, in fact, bidirectional plants, microbiota, environment shape complex chemical dialogue collectively orchestrates plantmicrobiome. The next stage research will require integration reductionist establish general understanding assembly function both natural managed environments.

Global population growth poses a threat to food security in an era of increased ecosystem degradation, climate change, soil erosion, and biodiversity loss. In this context, harnessing naturally-occurring processes such as those provided by plant-associated microorganisms presents promising strategy reduce dependency on agrochemicals. Biofertilizers are living microbes that enhance plant nutrition either mobilizing or increasing nutrient availability soils. Various microbial taxa including beneficial bacteria fungi currently used biofertilizers, they successfully colonize the rhizosphere, rhizoplane root interior. Despite their great potential improve fertility, biofertilizers have yet replace conventional chemical fertilizers commercial agriculture. last 10 years, multi-omics studies made significant step forward understanding drivers, roles, processes, mechanisms microbiome. However, translating knowledge microbiome functions order capitalize agroecosystems still remains challenge.

An extended root phenotype: the rhizosphere, its formation and impacts on plant fitness

The Plant Journal, Год журнала: 2020, Номер 103(3), С. 951 - 964

Опубликована: Апрель 23, 2020

Plants forage soil for water and nutrients, whose distribution is patchy often dynamic. To improve their foraging activities, plants have evolved mechanisms to modify the physicochemical properties microbial communities of rhizosphere, i.e. compartment under influence roots. This dynamic interplay in root-soil-microbiome interactions creates emerging that impact plant nutrition health. As a consequence, rhizosphere can be considered an extended root phenotype, manifestation effects genes on environment inside and/or outside organism. Here, we review current understanding how shape benefits it confers fitness. We discuss future research challenges applying solutions crops will enable us harvest phenotype.
