Plants have evolved with a plethora of microorganisms having important roles for plant growth and health. A considerable amount information is now available on the structure dynamics microbiota as well functional capacities isolated community members. Due to interesting potential due current challenges in crop production there an urgent need bring microbial innovations into practice. Different approaches microbiome improvement exist. On one hand strains or strain combinations can be applied, however, field success often variable urgently required. Smart, knowledge-driven selection needed use suitable delivery formulations. other hand, farming practices genotype influence thus functioning. Therefore, appropriate breeding leading improved plant-microbiome interactions are avenues increase benefit microbiota. In conclusion, different making new generation inoculants application microbiome-based agro-management lines could lead better microbiome.

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. Our results emphasize causes their ecological importance

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.

Drought and Salinity Stress Responses and Microbe-Induced Tolerance in Plants

Frontiers in Plant Science, Journal Year: 2020, Volume and Issue: 11

Published: Nov. 13, 2020

Drought and salinity are among the most important environmental factors that hampered agricultural productivity worldwide. Both stresses can induce several morphological, physiological, biochemical, metabolic alterations through various mechanisms, eventually influencing plant growth, development, productivity. The responses of plants to these stress conditions highly complex depend on other factors, such as species genotype, age size, rate progression well intensity duration stresses. These have a strong effect response define whether mitigation processes related acclimation will occur or not. In this review, we summarize how drought extensively affect growth in agriculture ecosystems. particular, focus Moreover, discuss mechanisms underlying plant-microbe interactions confer abiotic tolerance.

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.

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.
