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.

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.
