How Bacteria Outsmart Plants—Then Flee the Scene!

#MicroSky #PlantScience #Pseudomonas

Our new research in Nature Microbiology uncovers the sophisticated teamwork of Pseudomonas syringae, a notorious plant pathogen.

Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science!
(1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.

Science Magazine @science.org · 12d

Using precise spatial and temporal analysis, researchers in Science provide insight into how bacteria around the root interact both with the plant and with each other.

Learn more in this week's issue: https://scim.ag/3WgNajk

A confocal microscopy image shows root-colonizing bacteria clustering around an emerging lateral root, where localized glutamine leakage induces spatially confined reporter activity.

Thrilled to share our new paper in @science.org describing our discovery that bacteria can switch from competitors to bonafide predators when resources run dry—arming nanoscale “spears” (T6SS) to stab & consume neighbours.

Antagonism as a foraging strategy in microbial communities

In natural habitats, nutrient availability limits bacterial growth. We discovered that bacteria can overcome this limitation by acquiring nutrients by lysing neighboring cells through contact-dependen...

It was great to work with you too! Looking forward to the cool science we can do together in the future 😁

Julien Luneau @juliensluneau.bsky.social · Apr 4

Very happy I could contribute to the story with some single-cell imaging to look at the heterogeneity in flagellar expression and quantify its cost 🔬 I always love these movies, so mesmerizing 🤩
