Heavy‐Textured Rhizosphere Soils Enhance Microbial Nitrogen Fixation in a Desert Shrub Ecosystem

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
N2 fixation occurred in a heavy‐textured soil profile (0–60 cm), especially in rhizospheres, and the sandy soil had slight N2 fixation only in the bulk topsoil (0–20 cm). Available N, nitrate‐N, SOC, clay content, microbial activity, nifH gene abundance, and the relative abundance of certain microbial taxa were the main drivers of N2 fixation in soils.

Organization and control of genes encoding catabolic enzymes in Rhizobiaceae [PDF]

open access: yes, 1993
Rhizobiaceae, a diverse bacterial group comprising rhizobia and agrobacteria, symbiotic partnership with plants form nitrogen-fixing nodules on plant roots or are plant pathogens. Phenolic compounds produced by plants serve as inducers of rhizobial nodulation genes and agrobacterial virulence genes reflect their capacity to utilize numerous aromatics ...

Cold atmospheric plasma treatment induces oxidative stress and alters microbial community profile in the leaves of sweet basil (Ocimum basilicum var. Kiera) plant

open access: yesJournal of Food Science, Volume 90, Issue 2, February 2025.
Abstract The oxidative species generated by cold atmospheric plasma (CAP) treatment can impact the plant stress response system. We hypothesized that this response is not limited to the site of CAP application and it is transmitted through the plant. The resulting stress response can influence the plant microbiome on the intact plant.

Interactions with alloparents are associated with the diversity of infant skin and fecal bacterial communities in Chicago, United States

open access: yesAmerican Journal of Human Biology, Volume 37, Issue 1, January 2025.
Abstract Introduction: Social interactions shape the infant microbiome by providing opportunities for caregivers to spread bacteria through physical contact. With most research focused on the impact of maternal–infant contact on the infant gut microbiome, it is unclear how alloparents (i.e., caregivers other than the parents) influence the bacterial ...

Effects of glyphosate on antibiotic resistance in soil bacteria and its potential significance: A review

open access: yesJournal of Environmental Quality, Volume 54, Issue 1, Page 160-180, January/February 2025.
Abstract The evolution and spread of antibiotic resistance are problems with important consequences for bacterial disease treatment. Antibiotic use in animal production and the subsequent export of antibiotic resistance elements in animal manure to soil is a concern.

The Functional and Structural Succession of Mesic‐Grassland Soil Microbiomes Beneath Decomposing Large Herbivore Carcasses

open access: yesEnvironmental Microbiology, Volume 27, Issue 1, January 2025.
The study shows that nutrient–rich wildebeest carcasses significantly alter soil microbiome functions and structures over 18 months. Metabolic diversity increases and remains distinct, while initial microbial diversity is reduced but recovers. This highlights the long‐term impact of carcasses on soil health and ecosystem dynamics in grasslands ...

Identificación molecular de bacterias asociadas a la filosfera de plantas de arroz (Oryza sativa L), mediante técnicas de cultivo microbiano

open access: yesManglar, 2015
Las plantas albergan una gran diversidad de microorganismos, como hongos, bacterias, etc., que interactúan con ella y tienen una funcionalidad que va desde la patogenicidad, hasta la protección de la misma.

Medicago truncatula genotype drives the plant nutritional strategy and its associated rhizosphere bacterial communities

open access: yesNew Phytologist, Volume 245, Issue 2, Page 767-784, January 2025.
Summary Harnessing the plant microbiome through plant genetics is of increasing interest to those seeking to improve plant nutrition and health. While genome‐wide association studies (GWAS) have been conducted to identify plant genes driving the plant microbiome, more multidisciplinary studies are required to assess the relationships among plant ...

Characterization of microbiota composition and presence of selected antibiotic resistance genes in carriage water of ornamental fish. [PDF]

open access: yesPLoS ONE, 2014
International trade with ornamental fish is gradually recognized as an important source of a wide range of different antibiotic resistant bacteria. In this study we therefore characterized the prevalence of selected antibiotic resistance genes in the ...

The crop mined phosphorus nutrition via modifying root traits and rhizosphere micro‐food web to meet the increased growth demand under elevated CO2

open access: yesiMeta, Volume 3, Issue 6, December 2024.
The Elevated CO2 (eCO2) promoted wheat phosphorus (P) accumulation through increased root length and arbuscular mycorrhizal fungi (AMF) hyphal biomass, the concentration of organic acid anions and the alkaline phosphomonoesterase (ALP) activity. The eCO2 also increased the growth of ALP‐producing bacteria, protozoa and bacterivorous and fungivorous ...
