Patch‐Clamp‐ and 15N Isotope Tracer‐Based Techniques Reveal the Transport Characteristics of SlGAT1 and the Metabolic Flow of Exogenous GABA Under Salt Stress

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT γ‐Aminobutyric acid (GABA) plays an important role in plant growth, development, and stress resistance. Exogenous GABA works by increasing the content of endogenous GABA; therefore, GABA transport from the apoplast to the cytosol is critical. In this study, two GABA transporter genes, SlGAT1 and SlGAT2 were identified in tomato.

Detection of Diverse N-Acyl-Homoserine Lactones in Vibrio alginolyticus and Regulation of Biofilm Formation by N-(3-Oxodecanoyl) Homoserine Lactone In vitro

open access: yesFrontiers in Microbiology, 2017
Quorum sensing (QS) is a cell-to-cell communication system based on the exchange of small intercellular signal molecules, such as N-Acyl homoserine lactones (AHLs), which act as cell-density mediators of QS gene expression, and are highly variable both ...

Understanding the development of bacterial colony: Physiology, new technology, and modeling

open access: yesQuantitative Biology, Volume 13, Issue 4, December 2025.
Abstract Bacterial colonies, as dynamic ecosystems, display intricate behaviors and organizational structures that profoundly influence their survival and functionality. These communities engage in physiological and social interactions, resulting in remarkable spatial heterogeneity.

An Unprecedented Medium-Chain Diunsaturated N-acylhomoserine Lactone from Marine Roseobacter Group Bacteria

open access: yesMarine Drugs, 2018
N-acylhomoserine lactones (AHLs), bacterial signaling compounds involved in quorum-sensing, are a structurally diverse group of compounds. We describe here the identification, synthesis, occurrence and biological activity of a new AHL, N-((2E,5Z)-2,5 ...

Inhibition of homoserine dehydrogenase by formation of a cysteine-NAD covalent complex

open access: yesScientific Reports, 2018
Homoserine dehydrogenase (EC 1.1.1.3, HSD) is an important regulatory enzyme in the aspartate pathway, which mediates synthesis of methionine, threonine and isoleucine from aspartate.

Bacterial Diversity in Deep‐Sea Sediments of the North Atlantic Ocean and Their Biosynthesis of Secondary Metabolites

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
In this study, we isolated culturable bacteria associated with oceanic sediments and studied their production of secondary metabolites using metabolomics and genetic screening. Bacteria were cultivated from depths as great as 2000 m below sea level, with the majority of culturable taxa from all sampling sites belonging to the Pseudomonadota phylum. Our

Rhodotorula Mucilaginosa, a Quorum Quenching Yeast Exhibiting Lactonase Activity Isolated from a Tropical Shoreline

open access: yesSensors, 2014
Two microbial isolates from a Malaysian shoreline were found to be capable of degrading N-acylhomoserine lactones. Both Matrix Assisted Laser Desorption Ionization-Time of Flight-Mass Spectrometry and 18S rDNA phylogenetic analyses confirmed that these ...

HSP104 and HSP20‐L Are Required by Aspergillus nidulans in Response to Attack by Fungivorous Springtail Sinella curviseta

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
The heat shock proteins HSP104 and HSP20‐L of A. nidulans exhibit a reciprocal regulatory relationship to maintain physiological homeostasis in response to S. curviseta‐induced stress. ABSTRACT Heat shock proteins (HSPs) are conserved biomolecules that are consistently expressed and upregulated in response to stress.
