Stable, multigenerational transmission of the bean seed microbiome despite abiotic stress

This study tracks how drought or nutrient excess affects the transmission of bacterial communities in bean seeds across generations, finding stable transmission of 22 bacterial members regardless of parental treatment.

A novel "ceasefire" model to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean.

The paper uses a multi-omic approach to study Xanthomonas citri pv. fuscans interaction with common bean seeds, revealing a dynamic molecular dialogue and proposing a 'ceasefire' model for seed-pathogen interaction.

Seedling microbiota engineering using bacterial synthetic community inoculation on seeds

This study develops a method to engineer seedling microbiota using synthetic bacterial communities inoculated on seeds, showing they dominate seedling microbiota and influence plant fitness.

The Type VI secretion system of Stenotrophomonas rhizophila CFBP13503 limits the transmission of Xanthomonas campestris pv. campestris 8004 from radish seeds to seedlings

This study shows that the T6SS of S. rhizophila CFBP13503 inhibits Xcc8004 growth and transmission from radish seeds to seedlings.

Transmission of synthetic seed bacterial communities to radish seedlings: impact on microbiota assembly and plant phenotype

This study inoculates radish seeds with synthetic bacterial communities to assess their impact on microbiota assembly and plant phenotype, finding that some core taxa have detrimental effects on seedling development.

Defining composition and function of the rhizosphere microbiota of barley genotypes exposed to growth-limiting nitrogen supplies

This study investigates how nitrogen availability affects the composition and function of the rhizosphere microbiota in barley genotypes, showing host genetic control over microbial communities under nitrogen-limiting conditions.

Honey bees change the microbiota of pollen

This study shows that honey bees alter the microbial composition of pollen by adding bacterial symbionts and pathogens from their gut to the pollen they collect and process.

Temperature increase affects acetate-derived methane production in Alaskan lake sediments and wetland soils

This study examines how rising temperatures affect methane production and archaeal communities in Alaskan lake sediments and wetland soils, finding increased methane rates and shifts in microbial communities.

Seed microbiota revealed by a large-scale meta-analysis including 50 plant species

This study conducts a meta-analysis of 63 seed microbiota studies across 50 plant species, identifying core and flexible microbial taxa and their global distribution.

Single seed microbiota: assembly and transmission from parent plant to seedling

This study investigates seed microbiota assembly and transmission in bean and radish, showing that dominant bacterial taxa vary between plants and seeds, and that seed-borne taxa influence seedling phenotype.

Synergy of culture-dependent molecular identification and whole-community metabarcode sequencing for characterizing the microbiota of arable crop residues

This study compares culture-dependent and culture-independent methods for analyzing microbiota in crop residues, finding they provide complementary information about microbial diversity and function.

Asymmetric outcome of community coalescence of seed and soil microbiota during early seedling growth

The paper studies how seed and soil microbiota merge during seedling growth, finding that soil microbiota dominate the resulting communities.

Insect pollination is an ecological process involved in the assembly of the seed microbiota

This study shows insect pollination influences seed microbiota composition by introducing bee-associated bacteria, with honey bees having more impact than mason bees.

rpoB, a promising marker for analyzing the diversity of bacterial communities by amplicon sequencing

This study compares the rpoB gene and the V3V4 region of the 16S rRNA gene as markers for bacterial community analysis, finding rpoB provides better taxonomic resolution and accuracy in mock communities and nematode-associated microbiota.

Differences in resources use lead to coexistence of seed-transmitted microbial populations

The paper investigates how resource use differences affect the coexistence of microbial populations on radish seeds, identifying potential native bacteria that could limit pathogen transmission.

Crop residues in wheat-oilseed rape rotation system: a pivotal, shifting platform for microbial meetings

This study shows that crop residues in wheat-oilseed rape rotations act as a microbial ecosystem, with plant-specific microbes being replaced over time by soil-derived taxa, particularly faster in bacteria than fungi.
