Роль чувства кворума и инфохимических веществ во взаимодействии про- и микроэукариот в водных экосистемах

Abstract

This review presents key knowledge about the molecular interactions of unicellular organisms. Bacteria have quorum sensing (QS), which is regulated according to population density and controls gene expression, leading to changes in metabolism and behavior. Phytoplankton have a similar system – cells produce infochemicals that can either increase the resistance of recipient cells to stressors or trigger programmed cell death in them. Both quorum sensing molecules (QSM) and infochemicals are capable of influencing other aquatic organisms. QSMs can activate/inhibit phytoplankton cell growth, in turn, infochemicals can affect microbial community structure and inhibit the development of consumers. In addition, phytoplankton cells can disrupt bacterial QS by eliminating signaling molecules or imitating them. 

Keywords: quorum sensing, autoinducers, phytoplankton, bacteria, infochemical
