Nutrient Availability Does Not Affect Community Assembly in Root-Associated Fungi but Determines Fungal Effects on Plant Growth

Florian Frédéric Vincent Breider, Bing Bai

Nonmycorrhizal root-colonizing fungi are key determinants of plant growth, driving processes ranging from pathogenesis to stress alleviation. Evidence suggests that they might also facilitate host access to soil nutrients in a mycorrhiza-like manner, but t ...

The methylome of the model arbuscular mycorrhizal fungus, Rhizophagus irregularis, shares characteristics with early diverging fungi and Dikarya

Laure Menin, Natalia Gasilova

Early-diverging fungi (EDF) are distinct from Dikarya and other eukaryotes, exhibiting high N6-methyldeoxyadenine (6mA) contents, rather than 5-methylcytosine (5mC). As plants transitioned to land the EDF sub-phylum, arbuscular mycorrhizal fungi (AMF; Glom ...

Stability of tropical forest tree carbon-water relations in a rainfall exclusion treatment through shifts in effective water uptake depth

Charlotte Grossiord

Increasing severity and frequency of drought is predicted for large portions of the terrestrial biosphere, with major impacts already documented in wet tropical forests. Using a 4-year rainfall exclusion experiment in the Daintree Rainforest in northeast A ...

Impact of iron- and/or sulfate-reduction on a cis-1,2-dichloroethene and vinyl chloride respiring bacterial consortium: experiments and model-based interpretation

Christof Holliger, Julien Maillard, Alexandra Marie Murray

Process understanding of microbial communities containing organohalide-respiring bacteria (OHRB) is important for effective bioremediation of chlorinated ethenes. The impact of iron and sulfate reduction on cis-1,2-dichloroethene (cDCE) and vinyl chloride ...

In Situ Biostimulation of Cr(VI) Reduction in a Fast-Flowing Oxic Aquifer

Rizlan Bernier-Latmani, Daniel Scott Alessi

Hexavalent chromium is among the most common and hazardous inorganic contaminants in soils and groundwater. A promising in situ bioremediation approach is the delivery of electron donors to stimulate microbially mediated Cr(VI) reduction, producing relativ ...

Effect of Aging on the Stability of Microbially Reduced Uranium in Natural Sediment

Rizlan Bernier-Latmani, Barbora Bártová, Agnès Novotny, Yuheng Wang, Sophie Louise Bretagne, Luca Loreggian

Reductive immobilization of uranium has been explored as a remediation strategy for the U-contaminated subsurface. Via the in situ biostimulation of microbial processes, hexavalent U is reduced to less soluble tetravalent species, which are immobilized wit ...

Chlorinated ethene plume evolution after source thermal remediation: Determination of degradation rates and mechanisms

Christof Holliger, Julien Maillard, Jérémy Zimmermann, Alexandra Marie Murray

The extent, mechanism(s), and rate of chlorinated ethene degradation in a large tetrachloroethene (PCE) plume were investigated in an extensive sampling campaign. Multiple lines of evidence for this degradation were explored, including compound-specific is ...

Linking soil's volatilome to microbes and plant roots highlights the importance of microbes as emitters of belowground volatile signals

Alexandre Buttler, Richard Splivallo, Pierre Rémi Mariotte, Amarante Vitra

Plants and microbes release a plethora of volatiles that act as signals in plant-microbe interactions. Characterizing soil's volatilome and microbiome might shed light on the nature of relevant volatile signals and on their emitters. This hypothesis was te ...

Sphagnum Species Modulate their Phenolic Profiles and Mycorrhizal Colonization of Surrounding Andromeda polifolia along Peatland Microhabitats

Alexandre Buttler, Vincent Eric Jules Jassey

Sphagnum mosses mediate long-term carbon accumulation in peatlands. Given their functional role as keystone species, it is important to consider their responses to ecological gradients and environmental changes through the production of phenolics. We compa ...

Contrasting responses of bacterial and fungal communities to plant litter diversity in a Mediterranean oak forest

Mathieu Raymond Santonja

Tree species diversity of forested ecosystems control the diversity of leaf litter inputs to the soil, with cascading effects on the microbial communities colonizing decomposing litter. However, the extent to which bacterial and fungal communities inhabiti ...

Effect of crop rotation on mycorrhizal colonization and wheat yield under different fertilizer treatments

Pierre Rémi Mariotte

Break crops are used in agriculture to reduce soil pathogens and improve yield of subsequent cereal crops. However, they can also affect soil microbial communities beneficial to plant growth including arbuscular mycorrhizal fungi (AMF). Two wheat genotypes ...

Stoichiometric N:P flexibility and mycorrhizal symbiosis favour plant resistance against drought

Pierre Rémi Mariotte

Drought induces changes in the nitrogen (N) and phosphorus (P) cycle but most plant species have limited flexibility to take up nutrients under such variable or unbalanced N and P availability. Both the degree of flexibility in plant N:P ratio and of ro ...
