A Tyrosine Phospho-switch within the Longin Domain of VAMP721 modulates SNARE functionality

This study shows that phosphorylation of Y57 in VAMP721 regulates SNARE function by modulating its activity and interaction with cognate partners.

EXTRA LARGE G-PROTEIN 2 (XLG2) mediates cell death and hyperimmunity via a novel, apoplastic ROS-independent pathway in Arabidopsis thaliana

This study identifies XLG2 as a mediator of cell death and hyperimmunity in Arabidopsis through an apoplastic ROS-independent pathway, independent of known immune components.

De novo indol-3-ylmethyl glucosinolate biosynthesis, and not long-distance transport, contributes to defence of Arabidopsis against powdery mildew

This study shows that de novo biosynthesis of indol-3-ylmethyl glucosinolates in epidermal cells contributes to antifungal defense in Arabidopsis, while long-distance transport does not.

PBS3 is the missing link in plant-specific isochorismate-derived salicylic acid biosynthesis

The paper identifies PBS3 as the enzyme that converts isochorismate to salicylic acid via isochorismate-9-glutamate in plants.

Arabidopsis phytochelatin synthase 1, but not phytochelatin synthesis, functions in extracellular defense against multiple fungal pathogens

This study identifies PCS1 as a moonlighting protein involved in extracellular defense against fungal pathogens in Arabidopsis, independent of its known role in heavy metal detoxification.
