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.

An Arabidopsis leaf-infection assay with Alternaria alternata showing lesions on Col-0, defenseless (abi1-1 coi1 eds1 ein2 rbohD sid2) and cyp79b2b3 plants. The lesions are worst on cyb79b2b3, intermediate on the defenseless plant, and least on Col. Similarly, plants infected with Pseudomonas syringae show strongest susceptibility in an eds1 sid2 background, medium susceptibility in defenseless, and least in Col.

Born #OnThisDay in 1922, Esther Lederberg was the first to isolate the lambda phage in 1951. She characterised the lysogenic phase, whereby the phage are able to integrate into the bacterial genome, staying dormant. This discovery made them a model tool of study, leading to many more breakthroughs.
