Learning from agriculture: understanding low-dose antimicrobials as drivers of resistome expansion – Yaqi You – Frontiers in Microbiology

“Unconfined storage or land deposition of a large volume of animal waste causes its wide contact with the environment and drives the expansion of the environmental resistome through mobilome facilitated horizontal genet (sic, EB) transfer. “

Bird microbiome

Interspecific variations in the faecal microbiota of Procellariiform seabirds – Meagan L. Dewar – FEMS Microbiology Ecology

“Examining the faecal microbiota of three Procellariiform species (short-tailed shearwater, common diving petrel and fairy prion) provided a unique opportunity to not only characterise the gastrointestinal (GI) microbial composition of seabirds but to also examine the influence of stomach oils on the microbial community.”

Insect microbiome

Transient adult microbiota, gut homeostasis and longevity: Novel insights from the Drosophila model – Berra Erkosar, Francois Leulier – FEBS Letters

“In the last decade, Drosophila has emerged as a useful model to study host–microbiota interactions, creating an active research field with prolific publications.”

Plant microbiome

Building the crops of tomorrow: advantages of symbiont-based approaches to improving abiotic stress tolerance – Devin Coleman-Derr – Frontiers in Microbiology

“In recent years, studies have attempted to identify microbial symbionts capable of conferring the same stress-tolerance to their plant hosts, and new developments in genomic technologies have greatly facilitated such research. “

Convergence in mycorrhizal fungal communities due to drought, plant competition, parasitism, and susceptibility to herbivory: consequences for fungi and host plants – Catherine A. Gehring – Frontiers in Microbiology

“We found that drought and all three of the biotic interactions studied resulted in similar shifts in ectomycorrhizal fungal community composition, demonstrating a convergence of the community towards dominance by a few closely related fungal taxa.”

Nitrogen-fixing Rhizobium-legume symbiosis: are polyploidy and host peptide-governed symbiont differentiation general principles of endosymbiosis? – Gergely Maróti- Frontiers in Microbiology

“This review focuses on symbiotic plant cell development and terminal bacteroid differentiation and demonstrates the crucial roles of symbiotic peptides”

Disparate origins of Bradyrhizobium symbionts for invasive populations of Cytisus scoparius (Leguminosae) in North America – Kevin Horn – FEMS Microbiology Ecology

“To identify the geographic origin of nodule bacteria associated with invasion of the European legume Cytisus scoparius in the United States, isolates from 15 sites in six states were compared to > 200 Bradyrhizobium strains from indigenous legumes in the U.S., Mexico, Europe (six countries), Morocco, and Australia. “

Food microbiology

Weissella confusa: problems with identification of an opportunistic pathogen that has been found in fermented foods and proposed as a probiotic – Marilynn R. Fairfax – Frontiers in Microbiology

“Weissella confusa is found in fermented foods and has been suggested as a probiotic, but also causes sepsis and other serious infections in humans and animals.”

Stone microbiology

Application of calcifying bacteria for remediation of stones and cultural heritages – Navdeep Kaur Dhami – Frontiers in Microbiology

“The present review emphasizes about different causative agents leading to deterioration and application of microbially induced calcium carbonate precipitation as a novel and potential technology for dealing with these problems. “

Soil microbiology

Volatile-mediated interactions between phylogenetically different soil bacteria
Paolina Garbeva – Frontiers in Microbiology

“Here we report that volatile compounds emitted by different soil bacteria can affect the growth, antibiotic production and gene expression of the soil bacterium Pseudomonas fluorescens Pf0–1. “

Land-use influences the distribution and activity of high affinity CO-oxidizing bacteria associated to type I-coxL genotype in soil – Liliana Quiza – Frontiers in Microbiology

“The main objective of this study was to assess the impact of land-use and soil properties on coxL gene diversity and identify molecular indicators for the soil uptake of atmospheric CO.”

Abundance and community structure of ammonia-oxidizing Archaea and Bacteria in response to fertilization and mowing in a temperate steppe in Inner Mongolia –
Yong-Liang Chen – FEMS Microbiology Ecology

“… we investigated the effects of nitrogen (N) and phosphorus (P) fertilization and mowing on the abundance and community compositions of ammonia-oxidizing Bacteria (AOB) and Archaea (AOA) upon early (May) and peak (August) plant growth using quantitative PCR (qPCR), terminal-restriction fragment length polymorphism (T-RFLP), cloning and sequencing. “

Water microbiology

Biogeography of planktonic and benthic cyanobacteria in coastal waters of the Big Island, Hawai’i – Samuel D. Chamberlain – FEMS Microbiology Ecology

“To understand the patterns of cyanobacterial biogeography in relation to coastal environmental factors, we examined the diversity of planktonic and benthic cyanobacteria at 12 sites along the west coast of Hawaii’s Big Island.”

Rhizosphere heterogeneity shapes abundance and activity of sulfur-oxidizing bacteria in vegetated salt marsh sediments – François Thomas – Frontiers in Microbiology

“We combined next-generation amplicon sequencing of 16S rDNA and rRNA libraries with phylogenetic analyses of marker genes for two S-oxidation pathways (soxB and rdsrAB). Gene and transcript numbers of soxB and rdsrAB phylotypes were quantified simultaneously, using newly designed (RT)-qPCR assays.”

Neotropical Andes hot springs harbor diverse and distinct planktonic microbial communities – Luisa Delgado-Serrano – FEMS Microbiology Ecology

“In this study, we describe and compare the planktonic microbial communities present in five high-mountain hot springs with distinct geochemical characteristics, at varying altitudes and geographical locations in the Colombian Andes. “

Occurrence and activity of anammox bacteria in surface sediments of the southern North Sea – Nicole J. Bale – FEMS Microbiology Ecology
