Independent, Ongoing Clade-Specific Expansions of IS5 Elements in Pseudomonas syringae

The paper examines the distribution and expansion of a specific IS5 subclass in Pseudomonas syringae genomes, finding recent independent expansions and variable insertion site conservation.

Conditionally Redundant Bacteriocin Targeting by Pseudomonas syringae

This study shows Pseudomonas syringae strains produce multiple bacteriocins that act conditionally redundantly, where resistance to one sensitizes the target to others, suggesting potential for durable pathogen control.

Unusual Sulfur Requirements During Laboratory Growth of Luteibacter

This paper shows that some Luteibacter strains cannot use sulfate as a sulfur source and require organic or inorganic sulfur compounds or co-culture with fungi for growth.

Variation in the oxidative burst in response to wounding and bacterial infection among native and invading genotypes of yellow starthistle (Centaurea solstitialis)

This study compares immune responses and growth in native and invasive yellow starthistle genotypes, finding a trade-off between growth and defense in invasive populations.

Virulence in a Pseudomonas syringae Strain with a Small Repertoire of Predicted Effectors

The paper investigates a Pseudomonas syringae strain with a minimal type III effector repertoire, showing its virulence relies on both the type III secretion system and a new effector family, HopBJ1, which shares catalytic sites with E. coli toxins.
