Our paper on how a conveyor belt-associated protein of T9SS-driven gliding bacteria acts as a molecular switch, reversing T9SS rotation to fine-tune movement - like a smart conveyor or biological snowmobile adapting to changing terrain is out now in @mbio.bsky.social journals.asm.org/doi/10.1128/...
A molecular conveyor belt-associated protein controls the rotational direction of the bacterial type 9 secretion system | mBio
The type 9 secretion system (T9SS) is fundamental to bacterial gliding motility, pathogenesis, and surface colonization. Our findings reveal that the C-terminal region of the conveyor belt-associated ...

Motile bacterial zorbs demonstrate one of the most fascinating collective migration strategies I have ever encountered. Our lab's postdoc, Jitendra Gosai, gave an excellent talk on the sensory control of zorbs at the BLAST conference.

Wild & weird. Defs stashing away for my #CellBio course next semester!
Crazy stuff in PNAS

dental plaque bacterium 𝘊𝘰𝘳𝘺𝘯𝘦𝘣𝘢𝘤𝘵𝘦𝘳𝘪𝘶𝘮 𝘮𝘢𝘵𝘳𝘶𝘤𝘩𝘰𝘵𝘪𝘪 can divide into an unprecedented 14 daughter cells at once—then each daughter cell starts growing immediately in a rare process called multiple fission, achieving 0.5 mm per day of expansion

These mouth bacteria use a new type of cell division to make 14 cells at once
The newfound strategy seen in C. matruchotii might help oral bacteria recover lost territory after each eviction by toothbrushing.
