Pathogen Biocontrol Using Plant Growth-Promoting Bacteria (PGPR): Role of Bacterial Diversity

Microorganisms, Год журнала: 2021, Номер 9(9), С. 1988 - 1988

Опубликована: Сен. 18, 2021

A vast microbial community inhabits in the rhizosphere, among which, specialized bacteria known as Plant Growth-Promoting Rhizobacteria (PGPR) confer benefits to host plants including growth promotion and disease suppression. PGPR taxa vary ways whereby they curtail negative effects of invading plant pathogens. However, a cumulative or synergistic effect does not always ensue when bacterial consortium is used. In this review, we reassess disease-suppressive mechanisms present explanations illustrations for functional diversity and/or stability regarding these mechanisms. We also provide evidence mixtures, rather than individuals, are used protecting crops from various diseases, underscore critical determinant factors successful use mixtures. Then, evaluate challenges limitations achieving desired outcomes strain/species-rich assemblages, particularly relation their role management. addition, towards locating additive outcomes, highlight why how conferred need be categorized quantified different strains/species combinations. Finally, approaches needed developing mixtures with improved efficacy biocontrols utilization agricultural fields.

Ralstonia solanacearum: An Arsenal of Virulence Strategies and Prospects for Resistance

Annual Review of Phytopathology, Год журнала: 2023, Номер 61(1), С. 25 - 47

Опубликована: Июль 28, 2023

The group of strains constituting the Ralstonia solanacearum species complex (RSSC) is a prominent model for study plant-pathogenic bacteria because its impact on agriculture, owing to wide host range, worldwide distribution, and long persistence in environment. RSSC have led numerous studies aimed at deciphering molecular bases virulence, many biological functions mechanisms been described contribute infection pathogenesis. In this review, we put into perspective recent advances our understanding virulence strains, both terms inventory that participate process their evolutionary dynamics. We also present different strategies developed combat these pathogenic through control, antimicrobial agents, plant genetics, or microbiota engineering.

Exploring Cereal Metagenomics: Unravelling Microbial Communities for Improved Food Security

Microorganisms, Год журнала: 2024, Номер 12(3), С. 510 - 510

Опубликована: Март 2, 2024

Food security is an urgent global challenge, with cereals playing a crucial role in meeting the nutritional requirements of populations worldwide. In recent years, field metagenomics has emerged as powerful tool for studying microbial communities associated cereal crops and their impact on plant health growth. This chapter aims to provide comprehensive overview its enhancing food through exploration beneficial pathogenic interactions. Furthermore, we will examine how integration other tools can effectively address adverse effects security. For this purpose, discuss metagenomic data machine learning providing novel insights into dynamic interactions shaping plant-microbe relationships. We also shed light potential applications leveraging diversity epigenetic modifications improving crop resilience yield sustainability. Ultimately, revolutionized by harnessing between microbiota, paving way sustainable agricultural practices.

Microbial eco-evolutionary dynamics in the plant rhizosphere

Current Opinion in Microbiology, Год журнала: 2022, Номер 68, С. 102153 - 102153

Опубликована: Май 2, 2022

Microbial communities are vital for plant health and productivity. While most studies have underlined the ecology of plant-microbe interactions, accumulating evidence suggests rapid microbial evolution is also important, often occurring at ecological timescales within between generations. We review current mechanisms in rhizosphere, focusing on examples along mutualism-parasitism continuum. consider how can change ecosystem functioning via eco-evolutionary dynamics highlight importance intraspecies diversity as product raw material natural selection. conclude that acknowledging not only crucial understanding complex plant-microbiota interplay but an important prerequisite harnessing benefits soil microbes sustainable agriculture.

The host exocyst complex is targeted by a conserved bacterial type-III effector that promotes virulence

The Plant Cell, Год журнала: 2022, Номер 34(9), С. 3400 - 3424

Опубликована: Май 30, 2022

For most Gram-negative bacteria, pathogenicity largely depends on the type-III secretion system that delivers virulence effectors into eukaryotic host cells. The subcellular targets for majority of these remain unknown. Xanthomonas campestris, causal agent black rot disease crucifers such as Brassica spp., radish, and turnip, XopP, a highly conserved core-effector protein produced by X. which is essential virulence. Here, we show XopP inhibits function host-plant exocyst complex direct targeting Exo70B, subunit complex, plays significant role in plant immunity. interferes with exocyst-dependent exocytosis can do this without activating NOD-like receptor guards Exo70B Arabidopsis. In way, efficiently host's pathogen-associated molecular pattern (PAMP)-triggered immunity blocking pathogenesis-related protein-1A, callose deposition, localization FLAGELLIN SENSITIVE2 (FLS2) immune to plasma membrane, thus promoting successful infection. Inhibition related defenses represents an effective strategy, indicating ability pathogens adapt avoiding responses.

Novel Virus Identification through Metagenomics: A Systematic Review

Life, Год журнала: 2022, Номер 12(12), С. 2048 - 2048

Опубликована: Дек. 7, 2022

Metagenomic Next Generation Sequencing (mNGS) allows the evaluation of complex microbial communities, avoiding isolation and cultivation each species, does not require prior knowledge sequences present in sample. Applications mNGS include virome characterization, new virus discovery full-length viral genome reconstruction, either from preparations enriched culture or directly clinical environmental specimens. Here, we systematically reviewed studies that describe novel identification through samples different origin (plant, animal environment). Without imposing time limits to search, 379 publications were identified met search parameters. Sample types, geographical origin, enrichment nucleic acid extraction methods, sequencing platforms, bioinformatic analytical steps families described. The review highlights as a feasible method for origins, describes which kind heterogeneous experimental protocols are currently used provides useful information such commercial kits purification acids bioinformatics pipelines.
