Abstract Background Scientific approaches into modern agricultural systems, as opposed to the use of synthetic pesticides in food production, became important by exploring endophytic fungi capable protecting plants against pathogens for maximum crop productivity. Main body Diverse microbes colonizing internal tissue exhibit beneficial and pathological effects on plants. The assisted control pathogenic due their ability directly or indirectly promote plant health. Inefficient practices environmental factors contribute disease emergence Endophytic employed diverse mechanisms phytopathogen activating inducing resistance through gene expression, synthesis fungi-derived metabolite compounds, hormonal signaling molecules. mutual coexistence between host remains an mechanism suppression. An in-depth understanding selection interaction are managing challenges associated with endophyte biocontrol mechanisms. Conclusion Research findings bioinoculants advancing, antibiosis action agents (BCAs) can, however, be explored integrated management. Therefore, this review, was highlighted.

The leaves of plants are colonized by various microorganisms. In comparison to the rhizosphere, less is known about characteristics and ecological functions phyllosphere Phyllosphere microorganisms mainly originate from soil, air, seeds. composition affected abiotic factors. execute multiple influencing leaf longevity, seed mass, fruit development, homeostasis host growth. A plant can respond secondary metabolite secretion its immune system. Meanwhile, play an important role in stability environmental safety assessment. However, as a result instability environment poor cultivability current research, there still many limitations, such lack insight into mechanisms plant–microorganism interactions, roles growth processes, responses metabolites, etc. This review summarizes latest progress made research recent years. beneficial for deepening our understanding promoting plant–atmosphere pathogens, biological control.

Rhizosphere bacterial interactions and impact on plant health

Current Opinion in Microbiology, Год журнала: 2023, Номер 73, С. 102297 - 102297

Опубликована: Март 30, 2023

The rhizosphere is a chemically complex environment that harbors strikingly diverse microbial community. past few decades have seen rapid growth in the body of literature on plant–microbe–microbe interactions and plant health. Thus, aim this paper to review current knowledge (specifically bacteria) how these influence microbiomes impact This article discusses (i) recruits beneficial bacteria ii) competition between mechanisms/weapons employed bacteria–bacteria shapes microbiome turn affects heath. discussion mainly focuses interference competition, characterized by production specialized metabolites (antibacterial compounds) exploitative where bacterial strain restricts competitor's access nutrients such as through secretion siderophores could allude cooperation. Understanding mechanisms plant–bacteria provide insights into manipulate for improved agricultural outcomes.

Recruitment of the rhizo-microbiome army: assembly determinants and engineering of the rhizosphere microbiome as a key to unlocking plant potential

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Опубликована: Май 5, 2023

The viable community of microorganisms in the rhizosphere significantly impacts physiological development and vitality plants. assembly functional capacity microbiome are greatly influenced by various factors within rhizosphere. primary host plant genotype, developmental stage status, soil properties, resident microbiota. These drive composition, dynamics, activity microbiome. This review addresses intricate interplay between these how it facilitates recruitment specific microbes to support growth resilience under stress. also explores current methods for engineering manipulating microbiome, including plant-mediated manipulation, soil-related methods, microbe-mediated methods. Advanced techniques harness plant's ability recruit useful promising use rhizo-microbiome transplantation highlighted. goal this is provide valuable insights into knowledge, which will facilitate cutting-edge strategies enhanced stress tolerance. article indicates avenues future research field.

Emerging Pathways for Engineering the Rhizosphere Microbiome for Optimal Plant Health

Journal of Agricultural and Food Chemistry, Год журнала: 2023, Номер 71(11), С. 4441 - 4449

Опубликована: Март 8, 2023

The increasing impacts of global climate change on crop performance pose a significant threat to food security. rhizosphere microbiomes intimately interact with the plant and can largely facilitate plants in growth promotion stress resistance via multiple mechanisms. This review focuses approaches for harnessing produce beneficial effects toward enhanced productivity, including use organic inorganic amendments, microbial inoculants. Emerging methods, such as utilization synthetic consortia, host-mediated microbiome engineering, prebiotics made from specific root exudates, breeding promote plant–microbiome interactions, are highlighted. Updating our knowledge this field is critical understanding improving thereby enhancing adaptiveness changing environmental conditions.

Superiority of native soil core microbiomes in supporting plant growth

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Авг. 4, 2024

Native core microbiomes represent a unique opportunity to support food provision and plant-based industries. Yet, these are often neglected when developing synthetic communities (SynComs) plant health growth. Here, we study the contribution of native core, non-core non-native microorganisms production. We construct four alternative SynComs based on excellent growth promoting ability individual stain paired non-antagonistic action. One microbiome SynCom (SC2) shows high niche breadth low average variation degree in-vitro interaction. The promoting-growth effect SC2 can be transferred non-sterile environment, attributing colonization improvement rhizosphere function including nitrogen fixation, IAA production, dissolved phosphorus. Further, microbial fertilizer composite carrier (rapeseed cake + rice husk carbon) increase net biomass by 129%. Our results highlight fundamental importance boost authors show that have greater potential than both microorganisms.

Abstract Global increase in water scarcity is a serious problem for sustaining crop productivity. The lack of causes the degeneration photosynthetic apparatus, an imbalance key metabolic pathways, free radical generation as well weakens root architecture plants. Drought one major stresses that directly interferes with osmotic status plant cells. Abscisic acid (ABA) known to be player modulation drought responses plants and involvement both ABA‐dependent ABA‐independent pathways have been observed during drought. Concomitantly, other phytohormones such auxins, ethylene, gibberellins, cytokinins, jasmonic also confer tolerance crosstalk between different transcription factors at molecular level exists. A number drought‐responsive genes utilized producing transgenic improved tolerance. Despite relentless efforts, biotechnological advances failed design completely stress tolerant until now. microbiome hidden treasure possesses immense potential revolutionize strategies inducing resistance Root microbiota consist growth‐promoting rhizobacteria, endophytes mycorrhizas form consortium roots. Rhizospheric microbes are proliferous producers phytohormones, mainly cytokinin, ethylene enzymes like 1‐aminocyclopropane‐1‐carboxylate deaminase (ACC deaminase) metabolites exopolysaccharides help induce systemic against This review, therefore focuses on mechanisms plant‐microbe interactions under drought‐stressed conditions emphasizes importance drought‐tolerant improving productivity stress.
