5/ How do microbial🦠 communities communicate between single cells to behave like multicellular organisms? Awardee @C__Ellison hypothesizes that bacterial cell components (such as pili) are critical modulators. 🎉 Congrats Dr. Ellison! @universityofga 🙏#HFScout @BhayaDevaki

Excited to share my lab’s first preprint! We found that increasing DNA binding by type IV pili in an Acinetobacter pathogen can boost its natural transformation rates by ~100-fold, demonstrating that DNA binding is rate-limiting for natural transformation. biorxiv.org/content/10.1101/…

DNA binding is rate-limiting for natural transformation

Bacteria take up environmental DNA using dynamic appendages called type IV pili (T4P) to elicit horizontal gene transfer in a process called natural transformation. Natural transformation is widesp...

We wondered why the species Acinetobacter baylyi is so highly naturally transformable, and we found that its DNA-binding minor pilin FimT contains multiple DNA-binding residues that additively contribute to increased DNA binding.

Expression of A. baylyi FimT significantly boosts A. nosocomialis natural transformation and suggests that expression of a single gene may be sufficient to make less tractable organisms more genetically malleable.

Excited to share my last postdoc paper with @zgitai1, @shaevitz, the Dalia lab, Ned Wingreen, and Chenyi Fei! We found Acinetobacter baylyi cells localize their type IV pili in a line to interact with each other and regulate biofilm structure formation: rdcu.be/cYeln

Why do MSHA pili not exhibit hyperpiliation upon deletion of the retraction motor? Because in this system, the retraction motor is actually involved in extension! Check out my new preprint to learn more: biorxiv.org/content/10.1101/…

The canonical PilT retraction ATPase promotes both extension and retraction of the MSHA type IVa...

Diverse bacterial species use type IVa pili (T4aP) to interact with their environments. The dynamic extension and retraction of T4aP is critical for their function, but the mechanisms that regulate...

Hopefully next time will be in person but for now this will be a great opportunity to get the Acinetobacter community together!!!

My 1st first-author paper is officially published! This story started with a cool observation under the microscope (cells detaching in a wave!), and ended up characterizing an entire regulatory pathway inducing MSHA pilus retraction. Check it out! pnas.org/content/119/7/e2108…
