Research Highlight

Our manuscript on a new susceptibility hub that is targeted by Pseudomonas syringae effector proteins is now available at Plant Journal! This work was driven by Dr. Karl Schreiber with assistance from Jana Hassan. We identified an APETALA2-domain transcription factor (ABR1) as an interacting protein with multiple P. syringae effector proteins. Plants lacking ABR1 are less susceptible to infection, suggesting it is a negative regulator of immunity. Using RNAseq, we showed that immune responses are not generally enhanced in abr1 plants, suggesting that it is a susceptibilty hub. The manuscript is available here:
