Diversification of social identity in natural and experimental populations of a cooperative microbe
Microbes exhibit a diverse range of kin-discriminatory traits that alter social behavior as a function of genetic relatedness between interactants. Among motile bacteria that migrate across solid surfaces, several species exhibit territorial kin discrimination in which adjacent colonies of distinct social allotypes fail to merge as freely as do adjacent colonies of the same genotype. I will present recent work with the cooperative bacterium Myxococcus xanthus that has characterized the biogeographical distribution of distinct colony allotypes from micrometer to kilometer scales in natural soil populations, as well as evolution experiments with laboratory populations of M. xanthus which provide new insights into the evolutionary causes and genetic pathways by which bacterial kin discrimination can evolve.
Foccacia will be served.
