Plant Secondary Metabolites as Defenses, Regulators, and Primary Metabolites: The Blurred Functional Trichotomy

PLANT PHYSIOLOGY, Год журнала: 2020, Номер 184(1), С. 39 - 52

Plant chemicals known to mediate plant environment interactions also function as hormone-like regulators and precursors of primary metabolites. The kingdom produces hundreds thousands low molecular weight organic compounds. Based on the assumed functions these compounds, research community has classified them into three overarching groups: metabolites, which are directly required for growth; secondary (or specialized) plant–environment interactions; hormones, regulate organismal processes metabolism. For decades, this functional trichotomy metabolism shaped theory experimentation in biology. However, exact biochemical boundaries between different metabolite classes were never fully established. A new wave genetic chemical studies now further blurs by demonstrating that metabolites multifunctional; they can potent growth defense well sensu lato. Several adaptive scenarios may have favored diversity including signaling robustness cost-effective storage recycling. Secondary multifunctionality provide explanations ontogenetic patterns production refine our understanding plant–herbivore interactions, particular accounting discovery adapted herbivores misuse multiple purposes, some mirror their plants. In conclusion, recent work unveils limits current classification system Viewing integrated components metabolic networks dynamically environmental selection pressures transcend trophic levels improve interactions.

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.

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.

Root exudates are a pathway for plant-microbial communication and play key role in ecosystem response to environmental change. Here, we collate recent evidence that shows plants of different growth strategies differ their root exudation, can select beneficial soil microbial communities, drought affects the quantity quality exudation. We use this argue central involvement plant propose framework understanding how influence form function during after drought.
