Nitrogen deposition does not exacerbate phosphorus limitation of rhizosphere microbes in subalpine forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Advances and Challenges in Metatranscriptomic Analysis

Frontiers in Genetics, 2019
Sequencing-based analyses of microbiomes have traditionally focused on addressing the question of community membership and profiling taxonomic abundance through amplicon sequencing of 16 rRNA genes. More recently, shotgun metagenomics, which involves the random sequencing of all genomic content of a microbiome, has dominated this arena due to ...

Necromass chemistry drives the functional diversity of the necrobiome, resulting in microbe–organic matter feedbacks

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In temperate European forests, soil fungal communities, dominated by saprotrophic and ectomycorrhizal (ECM) species, represent almost 25% of soil organic carbon (C) in the soil.

Metatranscriptomic census of active protists in soils [PDF]

The ISME Journal, 2015
Abstract The high numbers and diversity of protists in soil systems have long been presumed, but their true diversity and community composition have remained largely concealed. Traditional cultivation-based methods miss a majority of taxa, whereas molecular barcoding approaches employing PCR introduce significant biases in reported ...

The impact of short‐term flooding on soil microbial communities, soil nitrogen and maize productivity in clay loam soils of Ohio, United States

Annals of Applied Biology, EarlyView.
A short‐term flood, implemented in a field experiment with sprinkler irrigation in maize production systems, increased soil moisture levels and reduced autoclaved citrate extractable protein, an indicator of soil biological health that reflects organically bound soil nitrogen, and also corresponded to greater differential abundance of soil bacterial ...

The Viral Fraction Metatranscriptomes of Lake Baikal

Microorganisms, 2022
This article characterises viral fraction metatranscriptomes (smaller than 0.2 µm) from the pelagic zone of oligotrophic Lake Baikal (Russia). The study revealed the dominance of transcripts of DNA viruses: bacteriophages and algal viruses. We identified transcripts similar to Pithovirus sibericum, a nucleocytoplasmic large DNA virus (NCLDV) isolated ...

Coastal upwelling systems as dynamic mosaics of bacterioplankton functional specialization

Frontiers in Marine Science
Coastal upwelling areas are extraordinarily productive environments where prokaryotic communities, the principal remineralizers of dissolved organic matter (DOM), rapidly respond to phytoplankton bloom and decay dynamics.

Metatranscriptomic analysis of extremely halophilic viral communities [PDF]

The ISME Journal, 2011
Abstract Hypersaline environments harbour the highest number of viruses reported for aquatic environments. In crystallizer ponds from solar salterns, haloviruses coexist with extremely halophilic Archaea and Bacteria and present a high diversity although little is known about their activity. In this work, we analyzed the viral expression

Microbiome of Apical Intracanal and Extraradicular Biofilms From the Same Roots of Teeth With Persistent Apical Periodontitis: An Observational Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim Bacterial biofilms around the apex are crucial in disease progression and persistence of apical periodontitis. While intracanal biofilms initiate infection, extraradicular biofilms contribute to treatment resistance and persistence. Thus, a comprehensive understanding of these biofilms may help elucidate mechanisms underlying persistent ...

Dinucleotide distance histograms for fast detection of rRNA in metatranscriptomic sequences [PDF]

, 2013
With the advent of metatranscriptomics it has now become possible to study the dynamics of microbial communities. The analysis of environmental RNA-Seq data implies several challenges for the development of efficient tools in bioinformatics.
