Abstract The phytohormone abscisic acid (ABA) regulates cell growth and plant development, and contributes to defence responses to pathogens. We previously showed that the Arabidopsis malectin‐like domain leucine‐rich repeat receptor‐like kinase (MLD‐LRR‐RLK) impaired oomycete susceptibility 1 (IOS1) attenuates ABA signalling during infection...

Homeostasis between the cytoplasmic plant hormone salicylic acid (SA) and its' inactive,vacuolar storage forms, SA-2-O-β-D-glucoside (SAG) and SA-β-D-Glucose Ester (SGE), regulates thefine-tuning of defense responses to biotrophic pathogens in Arabidopsis thaliana. This protocoldescribes a simplified, optimized procedure to extract and quantify...

Abstract An arsenal of effector proteins from plant pathogenic Phytophthora species manipulates their host from inside the cells. Phytophthora parasitica produces the effector AVH195 during an initial, biotrophic phase of infection. The protein transiently impairs plant immune-associated hypersensitive cell death in Nicotiana . ATG8 Interaction...

Background Plant pathogens secrete effector proteins into host cells to suppress immune responses and manipulate fundamental cellular processes. One of these processes is autophagy, an essential recycling mechanism in eukaryotic cells that coordinates the turnover of cellular components and contributes to the decision on cell death or survival....
