On P Systems as a Modelling Tool for Biological Systems [PDF]

open access: yes, 2006
We introduce a variant of P systems where rules have associated a real number providing a measure for the “intrinsic reactivity”of the rule and roughly corresponding to the kinetic coefficient which, in bio-chemistry, is usually associated to each ...

ExpI and PhzI are descendants of the long lost cognate signal synthase for SdiA. [PDF]

open access: yesPLoS ONE, 2012
SdiA of E. coli and Salmonella is a LuxR homolog that detects N-acyl homoserine lactones (AHLs). Most LuxR homologs function together with a cognate AHL synthase (a LuxI homolog), but SdiA does not.

Osmotic signaling governs sunscreen biosynthesis to safeguard desert cyanobacteria against desiccation

open access: yesmLife, Volume 5, Issue 2, Page 164-179, April 2026.
Abstract Mycosporine‐like amino acids (MAAs) are natural sunscreens synthesized by a wide range of organisms. Although the induction of MAA production by ultraviolet radiation is well established, the signaling pathways involved and specific functions of MAAs under other stress conditions remain poorly understood.

Molecular Detection of Pap II, OmpA, and LuxR Genes Responsible for Biofilm Formation in Acinetobacter baumannii Isolated from Hospitalized Patients

open access: yesMedical Journal of Babylon
Background: The first pathogen to be designated a “red-alert” human pathogen is Acinetobacter baumannii, which is on the list of infections that must be treated urgently with new antibiotics.

LuxR Solos in the Plant Endophyte Kosakonia sp. Strain KO348

open access: yesApplied and Environmental Microbiology, 2020
Cell-cell signaling in bacteria allows a synchronized and coordinated behavior of a microbial community. LuxR solos represent a subfamily of proteins in proteobacteria which most commonly detect and respond to signals produced exogenously by other microbes or eukaryotic hosts.

Cultivation‐Based Detection of a Novel High‐GC Nitrospira Derived From the Argentinian Copahue Volcano Area

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
In this cultivation‐based study, two novel moderately thermophilic Nitrospira enrichments were obtained from the geothermal field Las Máquinas in the Neuquén Province, Argentina. Both nitrite oxidizers, belonging to lineage V or the novel taxonomic lineage VIII, contain quorum‐sensing genes and a high genome GC content of 60.6% and 69.4%.

Transcriptomic and Functional Analyses Reveal Roles of AclR, a luxR-type Global Regular, in Regulating Motility and Virulence of Acidovorax citrulli

open access: yesMolecular Plant-Microbe Interactions, 2021
LuxR-type transcriptional regulators are essential for many physiological processes in bacteria, including pathogenesis. Acidovorax citrulli is a seedborne bacterial pathogen responsible for bacterial fruit blotch, which causes great losses in melon and ...

Pattern Formation with a Compartmental Lateral Inhibition System

open access: yes, 2014
We propose a compartmental lateral inhibition system that generates contrasting patterns of gene expression between neighboring compartments. The system consists of a set of compartments interconnected by channels.

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...
