Short-range C-signaling restricts cheating behavior during Myxococcus xanthus development

Y Hoang, Joshua Franklin, Yann Dufour & Lee Kroos
Starving Myxococcus xanthus bacteria use short-range C-signaling to coordinate building of multicellular mounds with differentiation from rods into spores during fruiting body development. A csgA mutant deficient in C-signaling can cheat on wild type (WT) in mixtures and form spores disproportionately, but our understanding of cheating behavior is incomplete. We report that cheating requires excess WT cells in the initial mixture and occurs during the mound-building phase of development. We subjected mixtures of WT and...
