Growth Peculiarities of the Saccharomyces cerevisiae Culture in the Presence of Exogenous Autoregulators of the Cell Population Density [PDF]

Учёные записки Казанского университета: Серия Естественные науки, 2015
A dose-dependent effect of budding suppression in yeasts, depending on their concentration (1.0, 10, and 100 μM) and the growth phase of the culture at the time of exposure to phenylethanol was observed during the study of growth peculiarities of the S ...

A Sinorhizobium meliloti-specific N-acyl homoserine lactone quorum-sensing signal increases nodule numbers in Medicago truncatula independent of autoregulation

Frontiers in Plant Science, 2014
N-acyl homoserine lactones (AHLs) act as quorum sensing signals that regulate cell-density dependent behaviors in many gram-negative bacteria, in particular those important for plant-microbe interactions.

Pseudomonas cremoricolorata Strain ND07 Produces N-acyl Homoserine Lactones as Quorum Sensing Molecules

Sensors, 2014
Quorum sensing (QS) is a bacterial cell-to-cell communication system controlling QS-mediated genes which is synchronized with the population density. The regulation of specific gene activity is dependent on the signaling molecules produced, namely N-acyl

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

Marine 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 ...
