Excited to see our new work published! We have established the evolutionary and ecological context of our favorite model Caulobacter and made some unexpected findings. Who would have thought that close relatives lack dimorphism? And have potential for phototrophy? www.nature.com/articles/s41...

The bacterial #SOSresponse unfolds in a defined temporal order, but how does this arise? @adityakamat.bsky.social @anjbadri.bsky.social &co show that intrinsic #promoter strength, modulated by #SigmaFactor usage, governs timing of SOS gene activation in Caulobacter @plosbiology.org 🧪 plos.io/4oAKf0Q
