DISRUPTION OF THE ENDOGENOUS INDOLE GLUCOSINOLATE PATHWAY IMPACTS THE ARABIDOPSIS THALIANA ROOT EXUDATION PROFILE AND RHIZOBACTERIAL COMMUNITY

This study shows that disrupting the indole glucosinolate pathway in Arabidopsis thaliana alters root exudate profiles and rhizobacterial communities.

Early viral infection of cyanobacteria drives bacterial chemotaxis in the oceans

This study shows that virus-infected cyanobacteria release metabolites that attract heterotrophic bacteria, enhancing nutrient transfer in marine ecosystems.

Impact of inoculation practices on microbiota assembly and community stability in a fabricated ecosystem

This study evaluates how different inoculation practices and harvesting times affect microbial community reproducibility in a fabricated ecosystem with Brachypodium distachyon.

Cysteine: an ancestral Cu binding ligand in green algae?

The paper shows that cysteine is an ancestral Cu(I) ligand in Chlamydomonas reinhardtii, as Zn deficiency disrupts Cu homeostasis and increases cysteine levels, which co-localize with Cu in acidocalcisomes.

Fine scale sampling reveals spatial heterogeneity of rhizosphere microbiome in young Brachypodium plants

The paper examines spatial microbial heterogeneity in Brachypodium roots using EcoFABs, revealing distinct microbial communities at root tips and bases with different functional gene profiles.

Reproducible growth of Brachypodium distachyon in fabricated ecosystems (EcoFAB 2.0) reveals that nitrogen form and starvation modulate root exudation

This study uses EcoFAB 2.0 to show nitrogen form and starvation affect Brachypodium root exudation, with specific compounds influencing bacterial and plant growth.

Water status shapes responses to ultraviolet radiation in two stress-tolerant mosses

This study examines how water status affects ultraviolet radiation responses in two moss species using transcriptomics and metabolomics.

Extensive plant use of exometabolites

The paper uses 13C-tracing to study plant uptake of exometabolites across multiple species, finding that uptake accounts for 23% of the carbon budget in Brachypodium distachyon and that some metabolites promote root growth.

Dynamic Phaeodactylum tricornutum Exometabolites Shape Surrounding Bacterial Communities

This study identifies specific exometabolites from the diatom Phaeodactylum tricornutum that influence bacterial community composition in isolation and in a community setting.

Assessing Comparative Microbiome Performance in Plant Cell Wall Deconstruction Using Multi-omics-Informed Network Analysis

The paper assesses microbiome performance in plant cell wall deconstruction using network analysis and identifies key microbial populations and enzymes involved.

Biofilm Interaction Mapping and Analysis (BIMA): A tool for deconstructing interspecific interactions in co-culture biofilms

The paper introduces BIMA, a method to analyze interspecific interactions in biofilm co-cultures by examining colony morphology, inhibition, invasion, and associated genes/metabolites.

A defined medium based on R2A for cultivation and exometabolite profiling of soil bacteria

The paper develops a defined medium (NLDM) for cultivating soil bacteria and profiling exometabolites, showing it supports growth of 53 diverse isolates and enables metabolite tracking via LC-MS/MS.

Conservation of isolate substrate preferences in mixed communities revealed through ribosomal marker protein profiling

The paper uses ribosomal marker protein profiling to show that isolate substrate preferences are conserved in a synthetic soil community and can be predicted by a weighted-sum model.

Physiological adaptations of leaf litter microbial communities to long-term drought

This study examines how microbial communities in leaf litter adapt to long-term drought through metatranscriptomic and metabolomic analyses in Californian grass and shrub ecosystems.

Multi-lab EcoFAB study shows highly reproducible physiology and depletion of soil metabolites by a model grass

The paper shows that Brachypodium distachyon consistently responds to soil conditions across labs, depleting soil metabolites and altering root morphology.

Construction of soil defined media using quantitative exometabolomic analysis of soil metabolites

This paper constructs environmentally relevant soil defined media using exometabolomic analysis of soil metabolites, showing they support bacterial growth and reveal substrate preferences.

Linking soil biology and chemistry using bacterial isolate exometabolite profiles

The paper integrates metabolite profiling, sequencing, and exometabolomics to link microbial community structure with environmental chemistry in soil.
