This study shows that Pseudomonas protegens CHA0 maintains its multi-host lifestyle and key traits after serial passage through insect larvae, with only minor and limited changes observed.

This study identifies novel chemical inducers of R-tailocin expression using a fluorescent reporter strain and screens over 1,500 compounds.

This study shows that heritable seed-borne bacteria shape the early assembly of the wheat rhizosphere microbiome through priority effects and niche exploitation.

The paper identifies regulators that control R-tailocin expression in Pseudomonas protegens CHA0, showing how DNA damage activates these genes through LexA-like and H-NS proteins.

The paper identifies single nucleotide mutations in surface-modifying enzymes that confer phage resistance in Pseudomonas protegens without compromising bacterial fitness.

The paper shows that fragmented microhabitats lead to more variable bacterial interactions, enabling alternative outcomes and supporting species diversity.

The paper shows that soil suppressive against plant pathogens also controls insect pests by reducing plant stress responses and altering microbiome dynamics.
