Bacterial quorum sensing: Cooperation and cheating
摘要
Abstract
Quorum sensing (QS),a cell-to-cell communication,regulates a variety of social behaviors,such as biofilm formation,public goods produce and gene horizontal transfer of bacteria.In the process of quorum sensing,public goods could be utilized by any members in the population,which was termed as cooperation.Notably,public goods also could be shared by the individuals who could not produce them,which was termed as cheating.Once cheaters come up,they possibly maintain equilibrium with cooperators,meanwhile they also possibly induce the collapse of population due to their rapid growth and shortage of public goods.Therefore,invasion of cheaters arouses wide attentions in medicine,agriculture,food science and so on regarded as a new strategy to control pathogens.In this study,based on the introduction about the theory of bacterial quorum sensing cooperation and cheating,we analyzed the factors influencing the formation and development of the relationship between cooperator and cheater.Moreover,we discussed the mechanism of stabilization in the relationship between cooperator and cheater,including kin selection,metabolic prudence,metabolic constraint (gene pleiotropy) and policing quorum sensing.Finally,some problems in current researches of quorum sensing cooperation and cheating were presented as well as the future research directions.We hoped this paper could deepen the understanding of bacterial quorum sen-sing and ecology of bacterial population.关键词
