Meloidogyne incognita parasitism is affected by Pseudomonas protegens CHA0 and its effects on tomato-associated microbiota Open
Background The multitrophic interactions in plant rhizosphere and endosphere can be beneficial or deleterious for the plant health. The parasitism by root-feeding nematodes is on the negative end of the interaction spectrum, and may be ver…

Diterpenoid Phytoalexins Shape Rice Root Microbiomes and Their Associations With Root Parasitic Nematodes Open
Rice synthesises diterpenoid phytoalexins (DPs) which are known to operate in defence against foliar microbial pathogens and the root‐knot nematode Meloidogyne graminicola . Here, we examined the role of DPs in shaping rice‐associated root…

Distinct changes in tomato-associated multi-kingdom microbiomes during Meloidogyne incognita parasitism Open
Background The interplay between root-knot nematode (RKN) parasitism and the complex web of host-associated microbiota has been recognized as pivotal for effective management of the pest. However, studies assessing this relationship have f…

Fertilizer regime and cultivar affect barley growth and rhizobiome composition Open
To combat climate change and environmental pollution, agriculture must reduce mineral fertilizer use and adopt sustainable, low-input, and organic practices. In such systems, plants depend on the soil microbiome for nutrient acquisition an…

Early assessment of fungal and oomycete pathogens in greenhouse irrigation water using Oxford nanopore amplicon sequencing Open
Water-borne plant pathogenic fungi and oomycetes are a major threat in greenhouse production systems. Early detection and quantification of these pathogens would enable us to ascertain both economic and biological thresholds required for a…

Cadmium accumulation in organisms from a spruce plantation amended with wood ash - an environmental risk? Open
Recycling of wood ash from power plants to forest plantations returns plant nutrients lost at harvest. However, wood ash contains a considerable amount of cadmium (Cd) that may accumulate in the forest food web, and eventually threaten env…

Deciphering the biological processes in root hairs required for N-self-fertilizing cereals Open
The need for increasing for crop productivity leads to a higher usage of synthetic fertilizers, which has tremendous effects on the environment. Nitrogen (N) is a crucial plant macronutrient, but the production of synthetic N fertilizer an…
View article: Fertilizer and cultivar affect the barley rhizobiome, while domestication age only affects growth at low nutrient levels
Fertilizer and cultivar affect the barley rhizobiome, while domestication age only affects growth at low nutrient levels Open
Modern plant breeding has provided barley cultivars that produce high yields when supplied with ample amounts of mineral fertilizer. This narrow selection criterion may have reduced key traits facilitating vital microbiome-plant interactio…
View article: Activity of root-knot nematodes associated with composition of a nematode-attached microbiome and the surrounding soil microbiota
Activity of root-knot nematodes associated with composition of a nematode-attached microbiome and the surrounding soil microbiota Open
We investigated if activity of the pre-infective juveniles (J2s) of root-knot nematodes is linked to the recruitment of a specific microbiome on the nematode surface and/or to the composition of the surrounding microbiota. For this, we det…

Clover Root Uptake of Cereal Benzoxazinoids (BXs) Caused Accumulation of BXs and BX Transformation Products Concurrently with Substantial Increments in Clover Flavonoids and Abscisic Acid Open
Metabolomic studies on root uptake and transformation of bioactive compounds, like cereal benzoxazinoids (BXs) in non-BX producing plants, are very limited. Therefore, a targeted mass-spectrometry-based metabolomics study was performed to …

Treated like dirt: Robust forensic and ecological inferences from soil <span>eDNA</span> after challenging sample storage Open
Biodiversity of soil is routinely assessed with environmental DNA—most often by massive parallel sequencing of marker genes (eDNA metabarcoding). Soil biodiversity may be investigated in relation to biodiversity research or as a tool in fo…

Distinct chemical resistance-inducing stimuli result in common transcriptional, metabolic, and nematode community signatures in rice root and rhizosphere Open
Induced resistance (IR), a phenotypic state induced by an exogenous stimulus and characterized by enhanced resistance to future (a)biotic challenge, is an important component of plant immunity. Numerous IR-inducing stimuli have been descri…

Genetic disruption of <i>Arabidopsis</i> secondary metabolite synthesis leads to microbiome-mediated modulation of nematode invasion Open
In-depth understanding of metabolite-mediated plant-nematode interactions can guide us towards novel nematode management strategies. To improve our understanding of the effects of secondary metabolites on soil nematode communities, we grew…

Rice diterpenoid phytoalexins are involved in defence against parasitic nematodes and shape rhizosphere nematode communities Open
Summary Rice diterpenoid phytoalexins (DPs) are secondary metabolites with a well known role in resistance to foliar pathogens. As DPs are also known to be produced and exuded by rice roots, we hypothesised that they might play an importan…

Bacteria Respond Stronger Than Fungi Across a Steep Wood Ash-Driven pH Gradient Open
Soil pH is probably the most important variable explaining bacterial richness and community composition locally as well as globally. In contrast, pH effects on fungi appear to be less pronounced, but also less studied. Here we analyze the …
