Plant and microbial features governing an endophytic lifestyle

Current Opinion in Plant Biology, Journal Year: 2023, Volume and Issue: 76, P. 102483 - 102483

Published: Nov. 5, 2023

Beneficial microorganisms colonizing internal plant tissues, the endophytes, support their host through growth promotion, pathogen protection, and abiotic stress alleviation. Their efficient application in agriculture requires understanding of molecular mechanisms environmental conditions that facilitate planta accommodation. Accumulating evidence reveals commensal employ similar colonization strategies as pathogenic counterparts. Fine-tuning immune response, motility, metabolic crosstalk accounts for differentiation. For a holistic perspective, experiments with microbial collections comprehensive genome data exploration are crucial. This review describes most recent findings on factors involved endophytic processes, focusing bacteria fungi, discusses required methodological approaches to unravel relevance within community context.

Symbiont plasticity as a driver of plant success

New Phytologist, Journal Year: 2024, Volume and Issue: 241(6), P. 2340 - 2352

Summary We discuss which plant species are likely to become winners, that is achieve the highest global abundance, in changing landscapes, and whether plant‐associated microbes play a determining role. Reduction fragmentation of natural habitats historic landscapes have led emergence patchy, hybrid novel where anthropogenic ecosystems prevail. In patchy with broad niches favoured. Plasticity degree association symbiotic may contribute broader optimization symbiosis costs benefits, by downregulating when it unnecessary upregulating beneficial. can also be expressed as switch from one type mutualism another, for example nutritive defensive increasing soil fertility associated increase parasite load. Upon dispersal, wide mutualistic partner receptivity another facet symbiont plasticity becomes beneficial, because plants not limited availability specialist partners arriving at new locations. Thus, under conditions change, allows optimize activity relationships, potentially allowing them winners maximizing geographic occupancy local abundance.

The hidden side of interaction: microbes and roots get together to improve plant resilience

Journal of Plant Interactions, Journal Year: 2024, Volume and Issue: 19(1)

Published: March 11, 2024

Plants have evolved various belowground traits to adapt the changing environments, and root-associated soil microbes play a crucial role in response, adaptation, resilience adverse environmental conditions. This comprehensive review explores diverse interactions between plants microbes, focusing on of microbiota, with particular emphasis arbuscular mycorrhizal fungi, plant responses How genotype, root traits, growth environments influence these interactions, consequently productivity, are discussed. Recent advances phenotyping, including traditional machine learning-based methods also presented as an innovative tool study characterize root-microbe interactions. Overall, studies highlight importance considering hidden side roots improve nutrition protection context sustainable agriculture face climate change.

Adding experimental precision to the realism of field observations: Plant communities structure bacterial communities in a glacier forefield

Environmental Microbiology, Journal Year: 2024, Volume and Issue: 26(2)

Published: Feb. 1, 2024

Abstract Ecological studies are aligned along a realism–precision continuum ranging from field observations to controlled lab experiments that each have their own strengths and limitations. insight may be most robust when combining approaches. In successional gradient, we found correlations between plant species composition soil bacterial communities, while Shannon diversity was unrelated vegetation characteristics. To add causal understanding of the processes community assembly, designed specifically test influence on communities. Using seeds our site, added different combinations surface‐sterilised homogenised samples in microcosms analysed communities 4 months later. Our results confirmed suggesting experimental shaped composition, unaffected. These reflect intimate plant–bacteria interactions important drivers health assembly. While this study provided insights into role plants underlying assembly did not experimentally manipulate other such as abiotic factors. Therefore, recommend multi‐factorial laboratory quantify relative importance factors contributing microbial composition.

Biotic interactions, evolutionary forces and the pan-plant specialized metabolism

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 379(1914)

Plant specialized metabolism has a complex evolutionary history. Some aspects are conserved across the green lineage, but many metabolites unique to certain lineages. The network of continuously diversified, simplified or reshaped during evolution streptophytes. Many routes pan-plant involved in plant defence. Biotic interactions recalled as major drivers lineage-specific metabolomic diversification. However, consequences this diversity context terrestrialization and land diversification into lineages bryophytes, lycophytes, ferns, gymnosperms angiosperms remain only little explored. Overall, hampers conclusions on scenarios that shaped metabolism. Recent efforts have brought forth new streptophyte model systems, an increase genetically accessible species from distinct lineages, functional data plants metabolic pathways. In review, we will integrate recent immune system with molecular its recognition. Based provide contextual framework metabolism, shape it impact adaptation terrestrial environment.

The Small Key to the Treasure Chest: Endogenous Plant Peptides Involved in Symbiotic Interactions

Plants, Journal Year: 2025, Volume and Issue: 14(3), P. 378 - 378

Published: Jan. 26, 2025

Plant growth and development are inextricably connected with rhizosphere organisms. Plants have to balance between strong defenses against pathogens while modulating their immune responses recruit beneficial organisms such as bacteria fungi. In recent years, there has been increasing evidence that regulatory peptides essential in establishing these symbiotic relationships, orchestrating processes include nutrient acquisition, root architecture modification, modulation. this review, we provide a comprehensive summary of the peptide families facilitate relationships plants

RIG-I Stimulation Enhances Effector Function and Proliferation of Primary Human CD8 T Cells

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 29, 2025

Abstract Cytotoxic CD8 T lymphocytes (CTL) are crucial in antiviral immune responses. However, their recruitment to infection sites renders them at risk of viral that could modulate effector activity. CTL express RIG-I detects cytosolic RNA and subsequently induce gene expression. Here, we investigated how influenza A virus (IAV) influence TCR-dependent IAV stimulated RIG-I, activated downstream pathways including TBK1 NF-⍰B, resulting type-I interferon secretion. Transfection with a pure ligand, tri-phosphorylated double stranded RNA(3p-dsRNA), not only these but also enhanced proliferation vitro protected from infection. Analogous positive effect on function, both ligand transfection degranulation cytokine Conversely, activation via CD3/CD28-crosslinking increased susceptibility Altogether, stimulation either by or 3p-dsRNA promoted cell intrinsic functions. These findings suggest agonists enhance prolong function immunotherapy.

Building microbial synthetic communities: get inspired by the design of synthetic plant communities

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 17, 2025

In the last decade, generation of host-associated microbial culture collections has allowed fine disentangling complex relationships between commensal microbes and their hosts, within-microbiota interactions. Specifically, these have been used to construct synthetic communities (SynComs), which allow reconstruction host microbiota in laboratory conditions. three recent perspective publications, importance this tool highlighted, ground rules utilization designing such SynComs laid out. It is important note that although are understand intricate ecological interactions occurring natural conditions, intraspecific genetic diversity present seldom considered design interspecific so far. Viewpoint, we therefore argue could benefit from developments plant communities, or SynComs. For instance, considering its effects on intra- plant-plant appears essential better predict highly productive stable communities. Therefore, within species undoubtedly represents an exciting opportunity innovative
