Assembly and ecological function of the root microbiome across angiosperm plant species

Proceedings of the National Academy of Sciences, Journal Year: 2018, Volume and Issue: 115(6)

Published: Jan. 22, 2018

Across plants and animals, host-associated microbial communities play fundamental roles in host nutrition, development, immunity. The factors that shape host–microbiome interactions are poorly understood, yet essential for understanding the evolution ecology of these symbioses. Plant roots assemble two distinct compartments from surrounding soil: rhizosphere (microbes roots) endosphere within roots). Root-associated microbes were key land underlie ecosystem processes. However, it is largely unknown how plant has shaped root communities, turn, affect ecology, such as ability to mitigate biotic abiotic stressors. Here we show variation among 30 angiosperm species, which have diverged up 140 million years, affects bacterial diversity composition. Greater similarity microbiomes between hosts leads negative effects on performance through soil feedback, with specific taxa potentially affecting competitive species. Drought also shifts composition microbiomes, most notably by increasing relative abundance Actinobacteria. this drought response varies across host-specific changes Streptomyces associated tolerance.

Harnessing rhizosphere microbiomes for drought-resilient crop production

Science, Journal Year: 2020, Volume and Issue: 368(6488), P. 270 - 274

Published: April 16, 2020

Root-associated microbes can improve plant growth, and they offer the potential to increase crop resilience future drought. Although our understanding of complex feedbacks between microbial responses drought is advancing, most knowledge comes from non-crop plants in controlled experiments. We propose that research efforts should attempt quantify relationships traits, explicitly focus on food crops, include longer-term experiments under field conditions. Overall, we highlight need for improved mechanistic during, particularly after, This requires integrating ecology with plant, microbiome, molecular approaches central making production more resilient climate.

Drought Stress and Root-Associated Bacterial Communities

Frontiers in Plant Science, Journal Year: 2018, Volume and Issue: 8

Published: Jan. 9, 2018

Root-associated bacterial communities play a vital role in maintaining health of the plant host. These exist complex relationships, where composition and abundance community members is dependent on number factors such as local soil chemistry, genotype phenotype, perturbations surrounding abiotic environment. One common perturbation, drought, has been shown to have drastic effects communities, yet little understood about underlying causes behind observed shifts microbial abundance. As drought may affect root both directly by modulating moisture availability, well indirectly altering chemistry phenotypes, we provide synthesis trends recent studies discuss possible directions for future research that hope will more knowledgeable predictions responses events.

Erosion reduces soil microbial diversity, network complexity and multifunctionality

The ISME Journal, Journal Year: 2021, Volume and Issue: 15(8), P. 2474 - 2489

Published: March 12, 2021

Abstract While soil erosion drives land degradation, the impact of on microbial communities and multiple functions remains unclear. This hinders our ability to assess true ecosystem services restore eroded environments. Here we examined effect at two sites with contrasting texture climates. Eroded plots had lower network complexity, fewer taxa, associations among relative non-eroded plots. Soil also shifted community composition, decreased abundances dominant phyla such as Proteobacteria, Bacteroidetes, Gemmatimonadetes. In contrast, led an increase in some bacterial families involved N cycling, Acetobacteraceae Beijerinckiaceae. Changes microbiota characteristics were strongly related erosion-induced changes multifunctionality. Together, these results demonstrate that has a significant negative diversity functionality.

Drought delays development of the sorghum root microbiome and enriches for monoderm bacteria

Proceedings of the National Academy of Sciences, Journal Year: 2018, Volume and Issue: 115(18)

Published: April 16, 2018

Significance Drought remains a critical obstacle to meeting the food demands of coming century. Understanding interplay between drought stress, plant development, and microbiome is central this challenge. Here, we demonstrate that causes enrichment distinct set microbes in roots, composed almost entirely monoderms, which lack outer membranes have thick cell walls. We under drought, roots increase production many metabolites, monoderms inhabiting drought-treated rhizosphere exhibit increased activity transporters connected with some these same compounds. The discovery drought-induced associated shifts metabolite exchange microbe reveal potential blueprint for manipulating microbiomes improved crop fitness.

Compositional shifts in root-associated bacterial and archaeal microbiota track the plant life cycle in field-grown rice

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.
