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.

🔗 rdcu.be/egczU

Pseudomonas syringae subpopulations cooperate by coordinating flagellar and type III secretion spatiotemporal dynamics to facilitate plant infection

Nature Microbiology - Single-cell gene expression analysis reveals phenotypic heterogeneity to enable bacterial specialization over the course of plant colonization.

The article echoes what I’ve seen and heard from peers: AI makes it easy to produce slick but shallow work that looks plausible on the surface, yet riddled with errors or bad assumptions underneath.

Your coworkers end up having to fix or redo it.

It’s workslop, and it’s spreading fast.
