🧵 Proud to present a tour de force by postdoc @gregbwhitfield.bsky.social solving the mystery of how bacterial Tad pili can extend and retract with a single motor ATPase. Great collaboration with Lynne Howell, @dr-lori-burrows.bsky.social, @ianyyen.bsky.social www.biorxiv.org/content/10.6...

Great collaboration with @guo-lab.bsky.social to determine an in situ architectural model of the Tad pilus machine. Be on the lookout soon for a preprint on the same topic by Grant Jensen and @viollierpat.bsky.social. #microsky

Excited to share that my postdoc work with Liu Yang, from @brunlabcaulo.bsky.social lab, is now out in @natcomms.nature.com ! How does your favourite bug grow? Elongation modes vary even between close relatives. We tracked PG insertion and uncovered surprising diversity within the Caulobacteraceae.

Multiple types of cell elongation have been described in bacteria, but little is known about how these strategies vary across species. Here, the authors use fluorescent D-amino acids to track the spat...

How does your favorite species elongate? 🧵 "Phenotypic plasticity in bacterial elongation among closely related species" by @mariedelaby.bsky.social, Liu Yang et al buff.ly/48Kw96x. How do cells elongate, all over, poles, middle? Close species do it the same way right? Not quite! #Microsky
