The insect- and plant-associated lifestyles of Pseudomonas protegens CHA0 are preserved following serial passage through insect larvae

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.

Exploring novel inducers of phage tail-like particle expression using a fluorescent reporter bacterium.

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

Priority effects of heritable seed-borne bacteria drive early assembly of the wheat rhizosphere microbiome

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

A LexA-like repressor and global H-NS-like regulators enable the fine-tuning of R-tailocin expression in environmental Pseudomonas

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.

Single nucleotide switches confer bacteriophage resistance to Pseudomonas protegens

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