Interspecies evolutionary dynamics mediated by public goods in bacterial quorum sensing

A very brief note on why bacterial evolution has physiology

“…Many QS systems have positive feedback ‘autoinducer’ characteristics that increase their sensitivity to population changes, but this property is not universal (Dogsa et al., 2021). QS pheromones have a wide diversity of chemical structures, so that some are species specific, whereas others like AHLs are shared by many different kinds of bacteria (Aguilar et al., 2021; Mukherjee & Bassler 2019; Spangler et al., 2019). Thus, these physiological tools can stimulate the formation of either single species or multispecies surface populations (Aframian & Eldar 2020; Yi et al., 2021).…”

Real-space condensation of reciprocal active particles driven by spontaneous symmetry breaking induced nonreciprocity

“…For instance, the flock of active spins [46][47][48] are expected to manifest similar real-space condensation driven by the emergent nonreciprocity. Moreover, the SSB in many other reciprocal active matter systems with their dynamics determined by intelligent decisionmaking rules, such as the intelligent materials [49], systems with herding dynamics [50,51], and systems with quorum sensing [52][53][54], etc., might also induce the nonreciprocity and give rise to new physics. We believe our findings and predictions will stimulate further theoretical and experimental efforts in revealing the emergent nonreciprocity driven new physics in various reciprocal many-body systems.…”
