Hypothesis
How does RssAB signaling coordinate the development of surface multicellularity in Serratia marcescens?
Conclusion
RssAB signaling is activated during the early stages of swarming and biofilm formation, affecting the duration of the lag period before surface migration and the integrity of biofilms.
Supporting Evidence
- RssAB signaling is specifically activated before surface migration in swarming development.
- Deletion of rssBA reduces the lag phase in swarming without affecting migration velocity.
- RssAB signaling affects the structural integrity of biofilms during early development.
Takeaway
Bacteria use a special signaling system called RssAB to decide when to move and form clusters on surfaces, which helps them survive better.
Methodology
The study involved monitoring RssAB signaling in single cells using a translational fusion protein and analyzing the effects of RssAB deletion on swarming and biofilm formation.
Limitations
The study does not explore the full range of environmental conditions affecting RssAB signaling.
