PpoR is a conserved unpaired LuxR solo of Pseudomonas putida which binds N-acyl homoserine lactones

BMC Microbiology, 2009
Background Only a small number of Pseudomonas putida strains possess the typical N-acyl homoserine lactone quorum sensing system (AHL QS) that consists of a modular LuxR family protein and its cognate LuxI homolog that produces the AHL signal.

How Salmonella Works Under Osmotic and Desiccation Stresses

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Salmonella remains one of the leading threats in foods with reduced water activity, where it can survive for long periods and cause outbreaks. Its persistence stems from a wide array of adaptive strategies shaped by the selective pressures imposed by low‐moisture foods.

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 ...

Volatiles from Subtropical Convolvulaceae That Interfere with Bacterial Cell-to-Cell Communication as Potential Antipathogenic Drugs [PDF]

, 2016
Increasing chronic bacterial infections create an urgent need for new antimicrobial agents or strategies for their control. Targetingvirulence is one of the alternative approaches to find new medicines to treat persistent infections due to bacteria with ...

Chinese Singaporean Children's Expectations About Peer Group Norms in the Context of Wealth and Ethnicity

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT United Nations SDG 10 focuses on reducing inequalities in civil society. To address the emergence of attitudes and reasoning about social exclusion based on wealth and ethnicity, Chinese Singaporean children's predictions about peer group inclusion decisions based on ethnicity (Chinese/Indian) and wealth (high/low) were investigated.

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

Trusting Wisely? Developmental Changes in How Children Learn and Adapt to Partner Trustworthiness

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Trusting selectively is a crucial ability in successfully navigating social environments: trusting a trustworthy partner maximizes mutual benefits; withholding trust from an untrustworthy partner minimizes chances of being exploited. Here, we ask how children's trust expectations and experienced trustworthiness inform their own trust decisions.

An Evolving Perspective on the Pseudomonas aeruginosa Orphan Quorum Sensing Regulator QscR

Frontiers in Cellular and Infection Microbiology, 2014
Many Proteobacteria govern responses to changes in cell density by using acyl-homoserine lactone (AHL) quorum-sensing (QS) signaling. Similar to the LuxI-LuxR system described in Vibrio fischeri, a minimal AHL QS circuit comprises a pair of genes, a luxI-

Imitation of Location Choices for Foreign Investments: The Role of Subnational Foreign Locations' Cultural Tightness

Journal of Management Studies, Volume 63, Issue 3, Page 998-1031, May 2026.
Abstract Firms are known to commonly imitate peers' foreign investment location choices. We shed further light on this phenomenon by exploring the role of foreign locations' cultural tightness, which refers to the prevalence of social norms in a location and the tolerance for deviance from them.
