A novel finding of intra-genus inhibition of quorum sensing in Vibrio bacteria
Quorum sensing is the process by which microbial cells sense and respond to the co-presence of others in their surrounding, through the detection of their autoinducers associated with gene expression regulation and thereby controlling many physiological ...

Autoinducer 2 Affects Biofilm Formation byBacillus cereus [PDF]
ABSTRACTCell-free supernatants from growingBacillus cereusstrain ATCC 10987 induced luminescence in aPhotorhabdus luminescensΔluxSmutant, indicating the production of functional autoinducer 2 (AI-2). The exogenous addition of in vitro synthesized AI-2 had an inhibitory effect on biofilm formation byB.

Synthesis and analysis of stable isotope-labelled N-acyl homoserine lactones [PDF]
Aliphatic aldehydes were deuterated at the alpha-position via a base-catalyzed exchange reaction with D2O. These deuterated building blocks were used for the synthesis of labelled analogues of quorum sensing signal molecules belonging to the three major ...

Regulation of autoinducer production in Salmonella typhimurium [PDF]
Salmonella typhimurium strain LT2 secretes an organic signalling molecule that can be assayed by its ability to activate one of two specific quorum‐sensing systems in Vibrio harveyi. Maximal activity is produced during mid‐ to late exponential phase when S. typhimurium is grown in the presence of glucose or other preferred carbohydrates. The signal is

Phytohormone-mediated interkingdom signaling shapes the outcome of rice-Xanthomonas oryzae pv. oryzae interactions [PDF]
Background: Small-molecule hormones are well known to play key roles in the plant immune signaling network that is activated upon pathogen perception. In contrast, little is known about whether phytohormones also directly influence microbial virulence ...

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome
By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

Functional analysis of the Pseudomonas aeruginosa autoinducer PAI [PDF]
A series of structural analogs of the Pseudomonas aeruginosa autoinducer [PAI, N-3-oxo-dodecanoyl homoserine lactone] were obtained and tested for their ability to act as autoinducers in stimulating the expression of the gene for elastase (lasB) by measuring beta-galactosidase production from a lasB-lacZ gene fusion in the presence of the ...

Phenazine‐Based Synthetic Biology to Signal Between Cells and Electrodes
ABSTRACT Bioelectronic systems that enable seamless communication between electronic devices and living systems represent a transformative frontier in biotechnology. Among available methodologies, redox based signaling offers unique advantages due to its ubiquity in biology and compatibility with standard electrochemical equipment, expanding on ...

The Evolution of Quorum Sensing as a Mechanism to Infer Kinship. [PDF]
Bacteria regulate many phenotypes via quorum sensing systems. Quorum sensing is typically thought to evolve because the regulated cooperative phenotypes are only beneficial at certain cell densities. However, quorum sensing systems are also threatened by
