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.

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.

Interactions between plants and soil shaping the root microbiome under abiotic stress

Biochemical Journal, Journal Year: 2019, Volume and Issue: 476(19), P. 2705 - 2724

Published: Oct. 11, 2019

Abstract Plants growing in soil develop close associations with microorganisms, which inhabit the areas around, on, and inside their roots. These microbial communities associated genes — collectively termed root microbiome are diverse have been shown to play an important role conferring abiotic stress tolerance plant hosts. In light of concerns over threat water nutrient facing terrestrial ecosystems, especially those used for agricultural production, increased emphasis has placed on understanding how conditions influence composition functioning ultimate consequences health. However, under will not only reflect shifts greater bulk community from plants recruit but also responses stress, include changes exudate profiles morphology. Exploring relative contributions these direct plant-mediated effects focus many studies recent years. Here, we review impacts affecting specifically flooding, drought, nitrogen phosphorus availability, that interact ultimately shape microbiome. We conclude a perspective outlining possible directions future research needed advance our complex molecular biochemical interactions between soil, plants, microbes determine stress.

Coordination between microbiota and root endodermis supports plant mineral nutrient homeostasis

Science, Journal Year: 2020, Volume and Issue: 371(6525)

Published: Nov. 20, 2020

Plant roots and animal guts have evolved specialized cell layers to control mineral nutrient homeostasis. These must tolerate the resident microbiota while keeping homeostatic integrity. Whether how root diffusion barriers in endodermis, which are critical for balance of plants, coordinate with is unknown. We demonstrate that genes controlling endodermal function model plant Arabidopsis thaliana contribute microbiome assembly. characterized a regulatory mechanism differentiation driven by profound effects on Furthermore, we this linked microbiota's capacity repress responses phytohormone abscisic acid root. Our findings establish endodermis as hub coordinating assembly mechanisms.

Two unequally redundant "helper" immune receptor families mediate Arabidopsis thaliana intracellular "sensor" immune receptor functions

PLoS Biology, Journal Year: 2020, Volume and Issue: 18(9), P. e3000783 - e3000783

Published: Sept. 14, 2020

Plant nucleotide-binding (NB) leucine-rich repeat (LRR) receptor (NLR) proteins function as intracellular immune receptors that perceive the presence of pathogen-derived virulence (effectors) to induce responses. The 2 major types plant NLRs "sense" pathogen effectors differ in their N-terminal domains: these are Toll/interleukin-1 resistance (TIR) domain-containing (TNLs) and coiled-coil (CC) (CNLs). In many angiosperms, RESISTANCE TO POWDERY MILDEW 8 (RPW8)-CC domain containing NLR (RNL) subclass CNLs is encoded by gene families, ACTIVATED DISEASE 1 (ADR1) N REQUIREMENT GENE (NRG1), act "helper" during multiple sensor NLR-mediated Despite important role immunity, knowledge specific, redundant, synergistic functions helper RNLs limited.
