Effect of Nitrate, Acetate and Hydrogen on Native Perchlorate-reducing Microbial Communities and Their Activity in Vadose Soil [PDF]

open access: yes, 2011
The effect of nitrate, acetate, and hydrogen on native perchlorate-reducing bacteria (PRB) was examined by conducting microcosm tests using vadose soil collected from a perchlorate-contaminated site.

Temporal dynamics of Prochlorococcus ecotypes in the Atlantic and Pacific oceans [PDF]

open access: yes, 2010
To better understand the temporal and spatial dynamics of Prochlorococcus populations, and how these populations co-vary with the physical environment, we followed monthly changes in the abundance of five ecotypes—two high-light adapted and three low ...

Redox Signaling through DNA [PDF]

open access: yes, 2016
Biological electron transfer reactions between metal cofactors are critical to many essential processes within the cell. Duplex DNA is, moreover, capable of mediating the transport of charge through its π-stacked nitrogenous bases.

DNA Hypomethylation Is One of the Epigenetic Mechanisms Involved in Salt‐Stress Priming in Soybean Seedlings

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Salt‐stress priming enhances the tolerance of plants against subsequent exposure to a similar stress. Priming‐induced transcriptomic reprogramming is mediated by multiple epigenetic mechanisms, the best known of which is histone modifications. However, not much is known about other epigenetic responses.

Molecular biology techniques as a tool for detection and characterisation of Mycobacterium avium subsp. paratuberculosis [PDF]

open access: yes, 2002
Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis) is the causative agent of paratuberculosis, also known as Johne’s disease, a chronic intestinal infection in cattle and other ruminants.

DNA Methylation Shapes Seed‐Borne Microbiome and Proteome Responses During Early Maize‐Beneficial Bacteria Interactions

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

Mitochondria‐Targeting Abasic Site‐Reactive Probe (mTAP) Enables the Manipulation of Mitochondrial DNA Levels

open access: yesAngewandte Chemie, Volume 137, Issue 36, September 1, 2025.
Mitochondria‐targeting water‐soluble probe mTAP exclusively reacts with mitochondrial abasic sites, enabling the manipulation of mitochondrial DNA levels under genotoxic stress. Abstract Mitochondrial DNA (mtDNA) encodes essential genes for mitochondrial and cellular functions and acts as a cell signaling molecule in innate immune and inflammatory ...

Removal of Antibiotic Resistance Genes in an Anaerobic Membrane Bioreactor Treating Primary Clarifier Effluent at 20 °C [PDF]

open access: yes, 2018
Anaerobic membrane bioreactors (AnMBR) play a key role in future plans for sustainable wastewater treatment and resource recovery because they have no energy-intensive oxygen transfer requirements and can produce biomethane for renewable energy.

Intratumoral Microorganisms in Tumors: Current Understanding and Emerging Therapeutic Strategies

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Tumors are no longer viewed as sterile but dynamic ecosystems harboring low‐biomass intratumoral microbiota. These microbes, derived from gut, oral cavity, or circulation, shape tumorigenesis and therapy response via core mechanisms: immunomodulation (regulating T cells, macrophages), metabolic reprogramming (SCFAs, indoles, bile acids), chronic ...
