Identifying plant genes shaping microbiota composition in the barley rhizosphere

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Июнь 16, 2022

A prerequisite to exploiting soil microbes for sustainable crop production is the identification of plant genes shaping microbiota composition in rhizosphere, interface between roots and soil. Here, we use metagenomics information as an external quantitative phenotype map host genetic determinants rhizosphere wild domesticated genotypes barley, fourth most cultivated cereal globally. We identify a small number loci with major effect on communities. One those, designated QRMC-3HS, emerges determinant composition. subject soil-grown sibling lines harbouring contrasting alleles at QRMC-3HS hosting microbiotas comparative root RNA-seq profiling. This allows us three primary candidate genes, including Nucleotide-Binding-Leucine-Rich-Repeat (NLR) gene region structural variation barley genome. Our results provide insights into footprint improvement plant's capacity microbes.

Co‐evolution within the plant holobiont drives host performance

EMBO Reports, Год журнала: 2023, Номер 24(9)

Опубликована: Июль 20, 2023

Plants interact with a diversity of microorganisms that influence their growth and resilience, they can therefore be considered as ecological entities, namely "plant holobionts," rather than singular organisms. In plant holobiont, the assembly above- belowground microbiota is ruled by host, microbial, environmental factors. Upon microorganism perception, plants activate immune signaling resulting in secretion factors modulate composition. Additionally, metabolic interdependencies antagonism between microbes are driving forces for community assemblies. We argue complex plant-microbe intermicrobial interactions have been selected during evolution may promote survival fitness associated holobionts. As part this process, evolved metabolite-mediated strategies to selectively recruit beneficial microbiota. Some these members show host-adaptation, from which mutualism rapidly arise. also co-evolved antagonistic activities restrict proliferation high pathogenic potential prevent disease development. Co-evolution within holobionts thus ultimately drives performance.

Microbes to support plant health: understanding bioinoculant success in complex conditions

Current Opinion in Microbiology, Год журнала: 2023, Номер 73, С. 102286 - 102286

A promising, sustainable way to enhance plant health and productivity is by leveraging beneficial microbes. Beneficial microbes are natural soil residents with proven benefits for performance health. When applied in agriculture improve crop yield performance, these commonly referred as bioinoculants. Yet, despite their promising properties, bioinoculant efficacy can vary dramatically the field, hampering applicability. Invasion of rhizosphere microbiome a critical determinant success. complex phenomenon that shaped interactions local, resident host plant. Here, we explore all dimensions cross-cutting ecological theory molecular biology microbial invasion rhizosphere. We refer famous Chinese philosopher strategist Sun Tzu, who believed solutions problems require deep understanding themselves, review major biotic factors determining effectiveness.

The Contribution of PGPR in Salt Stress Tolerance in Crops: Unravelling the Molecular Mechanisms of Cross-Talk between Plant and Bacteria

Plants, Год журнала: 2023, Номер 12(11), С. 2197 - 2197

Опубликована: Июнь 1, 2023

Soil salinity is a major abiotic stress in global agricultural productivity with an estimated 50% of arable land predicted to become salinized by 2050. Since most domesticated crops are glycophytes, they cannot be cultivated on salt soils. The use beneficial microorganisms inhabiting the rhizosphere (PGPR) promising tool alleviate various and represents strategy increase Increasing evidence underlines that PGPR affect plant physiological, biochemical, molecular responses stress. mechanisms behind these phenomena include osmotic adjustment, modulation antioxidant system, ion homeostasis, phytohormonal balance, nutrient uptake, formation biofilms. This review focuses recent literature regarding improve growth under salinity. In addition, very -OMICs approaches were reported, dissecting role modulating genomes epigenomes, opening up possibility combining high genetic variations plants action for selection useful traits cope conditions.

Microbiome homeostasis on rice leaves is regulated by a precursor molecule of lignin biosynthesis

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

Опубликована: Янв. 2, 2024

In terrestrial ecosystems, plant leaves provide the largest biological habitat for highly diverse microbial communities, known as phyllosphere microbiota. However, underlying mechanisms of host-driven assembly these ubiquitous communities remain largely elusive. Here, we conduct a large-scale and in-depth assessment rice microbiome aimed at identifying specific host-microbe links. A genome-wide association study reveals strong between genotype members four bacterial orders, Pseudomonadales, Burkholderiales, Enterobacterales Xanthomonadales. Some associations are to distinct host genomic locus, pathway or even gene. The compound 4-hydroxycinnamic acid (4-HCA) is identified main driver enrichment bacteria belonging Pseudomonadales. 4-HCA can be synthesized by plant's OsPAL02 from phenylpropanoid biosynthesis pathway. knockout mutant results in reduced Pseudomonadales abundance, dysbiosis microbiota consequently higher susceptibility plants disease. Our provides direct link metabolite homeostasis opening possibilities new breeding strategies.

Dissection of rhizosphere microbiome and exploiting strategies for sustainable agriculture

New Phytologist, Год журнала: 2024, Номер 242(6), С. 2401 - 2410

Опубликована: Март 17, 2024

Summary The rhizosphere microbiome plays critical roles in plant growth and provides promising solutions for sustainable agriculture. While the frequently fluctuates with soil environment, recent studies have demonstrated that a small proportion of is consistently assembled specific genotype regardless condition, which determined by host genetics. Based on these breakthroughs, involved exploiting plant‐beneficial function microbiome, we propose to divide into environment‐dominated genetic‐dominated components based their different assembly mechanisms. Subsequently, two strategies explore agricultural production are suggested, is, precise management agronomic practices, elucidation genetic basis breeding microbiome‐assisted crop varieties. We finally present major challenges need be overcome implement modulating microbiome.

The Green Revolution of the mid-20th century transformed agriculture worldwide and has resulted in environmental challenges. A new approach, Second Revolution, seeks to enhance agricultural productivity while minimizing negative impacts. Plant microbiomes play critical roles plant growth stress responses, understanding plant-microbiome interactions is essential for developing sustainable practices that meet food security safety challenges, which are among United Nations Sustainable Development Goals. This review provides a comprehensive exploration key deterministic processes crucial microbiome management strategies, including host effect, facilitator microbe-microbe interactions. hierarchical framework modulation proposed bridge gap between basic research applications. emphasizes three levels modulation: single strain, synthetic community, situ modulation. Overall, rational wide-ranging applications can potentially be core technology Revolution.
