Extracellular water withdrawal drives disease resistance in the phyllosphere

Charles Roussin‐Léveillée, Sabrina Gauthier, Yezhou Hu…·Peter Moffett

The paper shows that extracellular water status limits pathogen growth during both compatible and incompatible plant immune interactions, reframing the hypersensitive response as a desiccation mechanism.

Atypical immunity induced by extracellular water in plants

Faye Gaudreault‐Lafleur, Charles Roussin‐Léveillée, Sabrina Gauthier…·Peter Moffett

The paper investigates how plants respond to pathogen-induced extracellular water, finding that it triggers an atypical immune response mediated by salicylic acid.

Chloroplastic ROS bursts initiate salicylic acid biosynthesis in plant immunity

Charles Roussin‐Léveillée, Méliane St‐Amand, Philippe Desbiens‐Fortin…·Peter Moffett

This study shows that chloroplast-derived reactive oxygen species (cROS) trigger salicylic acid (SA) biosynthesis, a key step in plant immunity, and that pathogen effectors disrupt this process.
