Dynamics of rice microbiomes reveal core vertically transmitted seed endophytes

Microbiome, Journal Year: 2022, Volume and Issue: 10(1)

Published: Dec. 9, 2022

Plants and their associated microbiota constitute an assemblage of species known as holobionts. The plant seed microbiome plays important role in nutrient uptake stress attenuation. However, the core vertically transmitted endophytes remain largely unexplored.

Root colonization by beneficial rhizobacteria

FEMS Microbiology Reviews, Journal Year: 2023, Volume and Issue: 48(1)

Published: Dec. 12, 2023

Rhizosphere microbes play critical roles for plant's growth and health. Among them, the beneficial rhizobacteria have potential to be developed as biofertilizer or bioinoculants sustaining agricultural development. The efficient rhizosphere colonization of these is a prerequisite exerting their plant functions, but colonizing process underlying mechanisms not been thoroughly reviewed, especially nonsymbiotic rhizobacteria. This review systematically analyzed root compared it with that symbiotic pathogenic bacteria. also highlighted approaches improve efficiency proposed study rhizobacterial from holistic perspective microbiome under more natural conditions.

Superiority of native soil core microbiomes in supporting plant growth

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Aug. 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.

Prioritizing host phenotype to understand microbiome heritability in plants

New Phytologist, Journal Year: 2021, Volume and Issue: 232(2), P. 502 - 509

Published: July 21, 2021

Summary Breeders and evolutionary geneticists have grappled with the complexity of ‘genotype‐to‐phenotype map’ for decades. Now, recent studies highlight relevance this concept understanding heritability plant microbiomes. Because host phenotype is a more proximate cause microbiome variation than genotype, varies across anatomy development. Fine‐scale traits within organs suggests that well‐established ‘microbiome compartment’ should be refined. Additionally, work shows balance deterministic processes (including genetic effects) vs stochastic also over time space. Together, these findings suggest re‐centering – both as predictor readout function will accelerate new insights into heritability.

Comparative analysis of diversity and environmental niches of soil bacterial, archaeal, fungal and protist communities reveal niche divergences along environmental gradients in the Alps

Soil Biology and Biochemistry, Journal Year: 2022, Volume and Issue: 169, P. 108674 - 108674

Published: April 18, 2022

Although widely used in ecology, comparative analyses of diversity and niche properties are still lacking for microorganisms, especially focusing on variations. Quantifying the niches microbial taxa is necessary to then forecast how communities they compose might respond environmental changes. In this study, we first identified important topoclimatic, edaphic, spatial biotic drivers alpha beta bacterial, archaeal, fungal protist communities. Then, calculated breadth position each taxon along gradients determine these vary within among taxonomic groups. We found that edaphic were most both, community composition, all Protists bacteria presented largest breadths average, followed by archaea, with fungi displaying smallest. Niche generally decreased towards extremes, gradients, suggesting increased specialization highly selective environments. Overall, showed microorganisms have well defined niches, as do macro-organisms, likely driving part observed patterns Assessing variation more ecology should open new perspectives, tackle global change effects microbes.

Metagenomic and machine learning-aided identification of biomarkers driving distinctive Cd accumulation features in the root-associated microbiome of two rice cultivars

ISME Communications, Journal Year: 2023, Volume and Issue: 3(1)

Published: Feb. 22, 2023

Abstract Developing low-cadmium (Cd) rice cultivars has emerged as a promising avenue for food safety in Cd-contaminated farmlands. The root-associated microbiomes of have been shown to enhance growth and alleviate Cd stress. However, the microbial taxon-specific resistance mechanisms underlying different accumulation characteristics between remain largely unknown. This study compared low-Cd cultivar XS14 hybrid YY17 with five soil amendments. results showed that was characterized by more variable community structures stable co-occurrence networks soil-root continuum YY17. stronger stochastic processes assembly (~25%) rhizosphere than (~12%) suggested may higher changes properties. Microbial machine learning models jointly identified keystone indicator microbiota, such Desulfobacteria Nitrospiraceae Meanwhile, genes involved sulfur cycling nitrogen were observed among microbiome these two cultivars, respectively. Microbiomes root diversity functioning, significant enrichment functional related amino acid carbohydrate transport metabolism, cycling. Our findings revealed differences similarities communities associated well bacterial biomarkers predictive Cd-accumulation capacity. Thus, we provide new insights into recruitment strategies under stress highlight utility offering clues enhancing crop resilience stresses future.

Published: March 22, 2023

Microbes are accepted as the foremost drivers of rhizosphere ecology that influences plant health in direct or indirect ways. In recent years, rapid development gene sequencing technology has greatly facilitated study microbiome structure and function, various plant-associated microbiomes have been categorized. Additionally, there is growing research interest plant-disease-related microbes, some specific microflora beneficial to identified. This Review discusses microbiome's biological control pathways functions modulate defense against pathogens. How do enhance resistance? does core microbiome-associated synthetic microbial community (SynCom) improve health? further points out primary need develop smart agriculture practices using SynComs diseases. Finally, this provides ideas for future opportunities disease mining new resources.
