Bacterial Endophyte Colonization and Distribution within Plants

Microorganisms, Journal Year: 2017, Volume and Issue: 5(4), P. 77 - 77

Published: Nov. 25, 2017

The plant endosphere contains a diverse group of microbial communities. There is general consensus that these communities make significant contributions to health. Both recently adopted genomic approaches and classical microbiology techniques continue develop the science plant-microbe interactions. Endophytes are symbionts residing within for majority their life cycle without any detrimental impact host plant. use natural offers an opportunity maximize crop productivity while reducing environmental impacts agriculture. promote growth through nitrogen fixation, phytohormone production, nutrient acquisition, by conferring tolerance abiotic biotic stresses. Colonization endophytes crucial providing benefits Endophytic colonization refers entry, multiplication endophyte populations Lately, microbiome research has gained considerable attention but mechanism allowing plants recruit largely unknown. This review summarizes currently available knowledge about endophytic bacteria in various species, specifically discusses maize Populus endophytes.

Ecology and Evolution of Plant Microbiomes

Annual Review of Microbiology, Journal Year: 2019, Volume and Issue: 73(1), P. 69 - 88

Published: May 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.

Host selection shapes crop microbiome assembly and network complexity

New Phytologist, Journal Year: 2020, Volume and Issue: 229(2), P. 1091 - 1104

Published: Aug. 27, 2020

Plant microbiomes are essential to host health and productivity but the ecological processes that govern crop microbiome assembly not fully known. Here we examined bacterial communities across 684 samples from soils (rhizosphere bulk soil) multiple compartment niches (rhizoplane, root endosphere, phylloplane, leaf endosphere) in maize (Zea mays)-wheat (Triticum aestivum)/barley (Hordeum vulgare) rotation system under different fertilization practices at two contrasting sites. Our results demonstrate along soil-plant continuum is shaped predominantly by niche species rather than site or practice. From epiphytes endophytes, selection pressure sequentially increased diversity network complexity consequently reduced, with strongest effect endosphere. Source tracking indicates mainly derived gradually enriched filtered plant niches. Moreover, were dominated a few dominant taxa (c. 0.5% of phylotypes), bacilli identified as important biomarker for wheat barley Methylobacteriaceae maize. work provides comprehensive empirical evidence on selection, potential sources enrichment assembly, has implications future management manipulation sustainable agriculture.

Transmission of Bacterial Endophytes

Microorganisms, Journal Year: 2017, Volume and Issue: 5(4), P. 70 - 70

Published: Nov. 10, 2017

Plants are hosts to complex communities of endophytic bacteria that colonize the interior both below- and aboveground tissues. Bacteria living inside plant tissues as endophytes can be horizontally acquired from environment with each new generation, or vertically transmitted generation via seed. A better understanding bacterial endophyte transmission routes modes will benefit studies plant–endophyte interactions in agricultural natural ecosystems. In this review, we provide an overview take plants, including seeds pollen, soil, atmosphere, insects. We discuss well-documented understudied routes, identify gaps our knowledge on how reach plants. Where little is available endophytes, draw pathogens potential routes. Colonization roots soil best studied route, probably most important, although more aerial parts stomatal colonization needed, conclusively confirm vertical transfer. While transfer likely occurs, obligate strictly transferred symbioses unusual Instead, plants appear ability respond a changing by acquiring its microbiome anew over lifetime individuals.

The Plant Microbiome: From Ecology to Reductionism and Beyond

Annual Review of Microbiology, Journal Year: 2020, Volume and Issue: 74(1), P. 81 - 100

Published: June 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.

What Is There in Seeds? Vertically Transmitted Endophytic Resources for Sustainable Improvement in Plant Growth

Frontiers in Plant Science, Journal Year: 2018, Volume and Issue: 9

Published: Jan. 22, 2018

Phytobeneficial microbes, particularly endophytes, such as fungi and bacteria, are concomitant partners of plants throughout its developmental stages, including seed germination, root stem growth, fruiting. Endophytic microbes have been identified in that grow a wide array habitats; however, seed-borne endophytic not fully explored yet. Seed-borne endophytes great interest because their vertical transmission; potential to produce various phytohormones, enzymes, antimicrobial compounds, other secondary metabolites; improve plant biomass yield under biotic abiotic stresses. This review addresses the current knowledge on ability metabolites, influence growth stress mitigation.

The plant endosphere world – bacterial life within plants

Environmental Microbiology, Journal Year: 2020, Volume and Issue: 23(4), P. 1812 - 1829

Published: Sept. 21, 2020

Summary The plant endosphere is colonized by complex microbial communities and microorganisms, which colonize the interior at least part of their lifetime are termed endophytes. Their functions range from mutualism to pathogenicity. All organs tissues generally bacterial endophytes diversity composition depend on plant, organ its physiological conditions, growth stage as well environment. Plant‐associated in particular endophytes, have lately received high attention, because increasing awareness importance host‐associated microbiota for functioning performance host. Some endophyte known mostly lab assays, genome prediction few metagenome analyses; however, we limited understanding planta activities, particularly considering micro‐environments dynamics conditions. In our review, present recent findings environments, conditions colonization. Furthermore, discuss functions, interaction between plants methodological limitations research. We also provide an outlook needs future research improve role colonizing traits ecosystem functioning.
