Multi-scale dynamic imaging reveals that cooperative motility behaviors promote efficient predation in bacteria
2023
Overview
Many species, such as fish schools or bird flocks, rely on collective motion to forage, prey, or escape predators. Likewise,
Myxococcus xanthus
forages and moves collectively to prey and feed on other bacterial species. These activities require two distinct motility machines enabling adventurous (A) and social (S) gliding, however when and how these mechanisms are used has remained elusive. Here, we address this long-standing question by applying multiscale semantic cell tracking during predation. We show that: (1) foragers and swarms can comprise A- and S-motile cells, with single cells exchanging frequently between these groups; (2) A-motility is critical to ensure the directional movement of both foragers and swarms; (3) the combined action of A- and S-motile cells within swarms leads to increased predation efficiencies. These results challenge the notion that A- and S-motilities are exclusive to foragers and swarms, and show that these machines act synergistically to enhance predation efficiency.
Myxococcus xanthus forages and moves collectively to prey and feed on other bacterial species. Here, the authors challenge the conventional idea that during Myxococcus xanthus predation, A- and S-motilities are limited to specific forager and swarm roles and reveal a synergistic interaction between these motilities to enhance predation efficiency.
