Diverse Pseudomonas species engage in beneficial and suppressive interactions with the kiwifruit pathogen Pseudomonas syringae pv. actinidiae across Actinidia germplasm
Through metabarcoding, targeted isolation, and whole genome sequencing, we identified diverse Pseudomonads that appear to interact with Psa across kiwifruit germplasm.

Individually redundant effectors are collectively required for bacterial pathogen virulence
We developed MELEE, a mutated effector-leveraging evolution experiment, and found that the majority of Psa3's effectors are collectively required for virulence.

Genomic biosurveillance of the kiwifruit pathogen Pseudomonas syringae pv. actinidiae biovar 3 reveals adaptation to selective pressures in New Zealand orchards
We discovered effector loss variants (driven by ICE movement) through whole genome sequencing of 500 Psa3 isolates over a 12-year period.

Identification and characterization of innate immunity in Actinidia melanandra in response to Pseudomonas syringae pv. actinidiae
Through genome biosurveillance, effector screening, and transcriptomics, we characterised the immune response of resistant Actinidia melanandra to Psa3.

NbPTR1 confers resistance against Pseudomonas syringae pv. actinidiae in kiwifruit
By transforming the PTR1 resistance gene from Nicotiana benthamiana into susceptible kiwifruit, we have demonstrated a potential strategy for engineering HopZ5-specific resistance against Psa3.

Contrasting effector profiles between bacterial colonisers of kiwifruit reveal redundant roles converging on PTI-suppression and RIN4
Effector knockout and knock-in assays in virulent Psa3 and avirulent Pfm identified a number of redundantly required effectors that converge on the RIN4 plant immunity hub.

Effector loss drives adaptation of Pseudomonas syringae pv. actinidiae biovar 3 to Actinidia arguta
Four avirulence effectors contribute to Psa3 recognition in resistant kiwiberry, identified through genome biosurveillance and effector knockout screening.

Variation at the common polysaccharide antigen locus drives lipopolysaccharide diversity within the Pseudomonas syringae species complex
The TET operon determines the variability of LPS profiles in Psa, which is in turn correlated with tailocin susceptibility.
