The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, Volume 101, Issue 4, Page 1877-1903, August 2026.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Specificities and commonalities of the Planctomycetes plasmidome

Environmental Microbiology
ABSTRACT Although plasmids play a crucial role in antibiotic resistance and contemporary biotechnology, our comprehension of their natural ecological dynamics remains restricted to a few bacterial groups. Planctomycetes is a bacterial phylum with unusual molecular and cellular biology for which little is known about its plasmidome. This

“Candidatus Uabimicrobium helgolandensis”—a planctomycetal bacterium with phagocytosis-like prey cell engulfment, surface-dependent motility, and cell division

mBio
The unique cell biology presented by members of the phylum Planctomycetota has puzzled researchers ever since their discovery. Initially thought to have eukaryotic-like features, their traits are now recognized as exceptional but distinctly bacterial ...

Abundance, diversity and depth distribution of Planctomycetes in northern Sphagnum-dominated wetlands

Frontiers in Microbiology, 2012
Members of the bacterial phylum Planctomycetes inhabit various aquatic and terrestrial environments. In this study, fluorescence in situ hybridization (FISH) was applied to assess the abundance and depth distribution of these bacteria in nine different ...

Organic Matter Type Defines the Composition of Active Microbial Communities Originating From Anoxic Baltic Sea Sediments

Frontiers in Microbiology, 2021
Carbon cycling in anoxic marine sediments is dependent on uncultured microbial communities. Niches of heterotrophic microorganisms are defined by organic matter (OM) type and the different phases in OM degradation.

Nutrient disturbance in a shallow aquaculture pond impacts Microcystis gene expression but does not impact bacterial community function during bloom conditions

Journal of Phycology, Volume 62, Issue 4, Page 1297-1310, August 2026.
Abstract Cyanobacterial harmful algal blooms (cHABs) are worldwide issues. Reduced nitrogen forms (ammonium and urea) have recently been measured in freshwater systems at concentrations not previously recorded. These reduced nitrogen forms have been shown to favor the proliferation of harmful cyanobacteria.

Anammox Planctomycetes have a peptidoglycan cell wall [PDF]

Nature Communications, 2015
AbstractPlanctomycetes are intriguing microorganisms that apparently lack peptidoglycan, a structure that controls the shape and integrity of almost all bacterial cells. Therefore, the planctomycetal cell envelope is considered exceptional and their cell plan uniquely compartmentalized.

How Host Phylogeny, Diet, and Habitat Affect Gut Microbial Diversity in Wild Snakes

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Gut microbiota plays critical roles in host digestion, immune regulation, neurochemical signaling, and metabolic homeostasis. Based on wild snakes (73 individuals from 23 species) from China, we explored the composition, characteristics, and functions of gut microbes across different groups using fecal metagenomic samples; further we explored the ...

Planctomycetes in Lakes: Poor or Strong Competitors for Phosphorus? [PDF]

Applied and Environmental Microbiology, 2014
ABSTRACT Experiments were conducted with water samples from two perialpine lakes with differing eutrophication status in order to examine the effects of inorganic-nutrient amendments (nitrogen as NO 3 − or NH 4 + and phosphorus as PO 4

Effect of composting on bacterial communities in poultry litter generated using conventional and organic production systems

Journal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Poultry production generates substantial quantities of poultry litter, which can be applied to agricultural soils as organic fertilizer. Although this production system is sustainable, it can increase the microbial numbers and change ecological interactions and trophic networks in the soil.
