Sixteen common misconceptions about the evolution of cooperation in humans (2011, background): “, 2002a), as well as experimental evolution tests of these models (Diggle et al., 2007; Griffin et al., 2004; Kümmerli et al., 2009).”
Bacterial competition: surviving and thriving in the microbial jungle (2010, result): “Another study, using similar culture conditions, confirmed that both lasR mutants, which are 'signal blind', and mutants deficient in signal production had higher fitness than the wild-type parent strain when they were present as a minority in the populatio”
The problem of pattern and scale in ecology: what have we learned in 20 years? (2013, background): “A similar type of collective behaviour, biofilm development, has been invoked to explain the increased virulence of the bacterium Pseudomonas aeruginosa in acute forms of infections (Diggle et al. 2007).”
Exploiting Quorum Sensing To Confuse Bacterial Pathogens (2013, background): “This has been confirmed by in vitro experiments showing that the frequency of cheaters (receptor mutants) increased over time when cocultured with cooperators (WT bacteria) in media requiring extracellular QS-regulated products for growth (346, 347).”
Emergence of Spatial Structure in Cell Groups and the Evolution of Cooperation (2010, methodology): “Previous work performed with bacteria in liquid planktonic culture has concluded that cooperative cell phenotypes cannot be selectively favored within a single population also containing exploitative cells [17,19,20].”
Engineering microbial consortia: a new frontier in synthetic biology. (2008, background): “Such studies have already demonstrated that cheating strains, sub-populations that compete with the primary population by enjoying the benefits of a costly corporate behavior without contributing to it, arise within a population of cooperating bacteria more frequently when the individuals in the pop”
Indole as an intercellular signal in microbial communities. (2010, background): “Although speculative, some individuals may avoid the cost of producing indole by exploiting the signal from the local bacterial consortia in line with the kin selection model (Diggle et al., 2007b).”
Bacterial Quorum-Sensing Network Architectures (2009, neutral): “aeruginosa, which use quorum sensing to up-regulate virulence at HCD, can be invaded both by mutants that do not produce autoinducers and by mutants that do not respond to autoinducers (16, 102).”
Quorum Sensing and Bacterial Social Interactions in Biofilms (2012, background): “These researchers also showed a solution to this problem of exploitation by kin selection, which might be highly important in microbial social behaviors because of their clonal reproduction and relatively local interactions [65].”
