Identification of sdiA-regulated genes in a mouse commensal strain of Enterobacter cloacae

Frontiers in Cellular and Infection Microbiology, 2015
Many bacteria determine their population density using quorum sensing. The most intensively studied mechanism of quorum sensing utilizes proteins of the LuxI family to synthesize a signaling molecule of the acylhomoserine lactone (AHL) type, and a ...

Cdk5 regulatory subunit-associated protein 1 knockout mice show hearing loss phenotypically similar to age-related hearing loss

Molecular Brain, 2021
Mitochondrial dysfunction is associated with aging and age-related hearing loss (AHL). However, the precise mechanisms underlying the pathophysiology of hearing loss remain unclear.

Fritz Scheffer Under National Socialism: Assessing His Political Involvement

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Aims This article examines the role of soil scientist Fritz Scheffer (1899–1979) under National Socialism and offers a critical assessment of his scientific, institutional, and political positioning between 1933 and 1945. It asks how Scheffer shaped his career within the tension between disciplinary specialization, political expectations, and ...

Hypersensitive Response of Plasmid-Encoded AHL Synthase Gene to Lifestyle and Nutrient by Ensifer adhaerens X097

Frontiers in Microbiology, 2017
It is known that some bacteria, especially members of the family Rhizobiaceae, have multiple N-acyl homoserine lactones (AHL) synthase genes and produce multiple AHL signals.

One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

Network analysis uncovers the master role of WRKY transcription factors in Arabidopsis thaliana response to N-acyl homoserine lactones

CABI Agriculture and Bioscience
Background Plants can perceive bacterial molecules such as the quorum sensing signals N-acyl homoserine lactones (AHL), thus modifying their fitness in response to environmental factors. Even though the benefits conferred by AHL depend on various hormone

Targeting Acyl Homoserine Lactone (AHL) of Pseudomonas aeruginosa Responsible for Biofilm Formation using Plant Metabolites

Journal of Pure and Applied Microbiology, 2019
AHL (acyl homoserine lactone) is a signaling molecule responsible for communication in gram negative bacteria, which is liable for bacterial virulence as well as biofilm formation. This study aims in targeting the AHL formation and AHL mediated virulence

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Plants Secrete Substances That Mimic Bacterial N-Acyl Homoserine Lactone Signal Activities and Affect Population Density-Dependent Behaviors in Associated Bacteria

Molecular Plant-Microbe Interactions, 2000
In gram-negative bacteria, many important changes in gene expression and behavior are regulated in a popula tion density-dependent fashion by N-acyl homoserine lac tone (AHL) signal molecules.
