A review on the plant microbiome: Ecology, functions, and emerging trends in microbial application

Journal of Advanced Research, Journal Year: 2019, Volume and Issue: 19, P. 29 - 37

Published: March 20, 2019

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. This paper reviews importance functionalities bacterial discusses concepts regard plant-associated bacteria.

Root Exudation of Primary Metabolites: Mechanisms and Their Roles in Plant Responses to Environmental Stimuli

Frontiers in Plant Science, Journal Year: 2019, Volume and Issue: 10

Published: Feb. 21, 2019

Root exudation is an important process determining plant interactions with the soil environment. Many studies have linked this to nutrient mobilization. Yet, it remains unresolved how controlled and exactly under what circumstances plants benefit from exudation. The majority of root exudates include primary metabolites (sugars, amino acids organic acids) believed be passively lost used by rhizosphere-dwelling microbes. In review, we synthetize recent advances in ecology biology explain propose mechanisms which controlled, role their plays acquisition strategies. Specifically, a novel conceptual framework for exudates. This built upon two main concepts: (i) driven diffusion, microbes both modulating concentration gradients therefore diffusion rates depending on nutritional status; (ii) exuded metabolite concentrations can sensed at tip signals are translated modify architecture. flux through mostly located tip, where lack cell differentiation favors soil. We show examples senses changes translate that into growth. Plants either controlling source/sink processes or expressing regulating efflux carriers, challenging idea as purely unregulated passive process. Through exudate flux, locally enhance many common serve sensors integrators status availability surrounding Plant-associated micro-organisms also constitute strong sink carbon thereby increasing affecting Understanding of, effects that, environmental stimuli magnitude type will ultimately improve our knowledge CO2 emissions, ecosystem functioning sustainability agricultural production.

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.

Modulation of the Root Microbiome by Plant Molecules: The Basis for Targeted Disease Suppression and Plant Growth Promotion

Frontiers in Plant Science, Journal Year: 2020, Volume and Issue: 10

Published: Jan. 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.

Linking Plant Secondary Metabolites and Plant Microbiomes: A Review

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 12

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.
