Extracellular water withdrawal drives disease resistance in the phyllosphere

Charles Roussin‐Léveillée, Sabrina Gauthier, Yezhou Hu, Jie Zhu, Faye Gaudreault‐Lafleur, Soline Marty, Antoine Pelletier, Alexis Roy, Laurent D. Noël, Gitta Coaker, Xiufang Xin, 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, Gaële Lajeunesse, Alexis Roy, Isabelle Laforest‐Lapointe, 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.

Glycan recognition by a plant sentinel immune receptor

Pedro Jiménez‐Sandoval, Caroline Broyart, Owen Kentish, Hyun Kyung Lee, Klara Čuljak, Uwe Osswald, Meriem Aitouguinane, Emanuele Tettamanti, Manon Schmidli, Lu Zhang, Charles Roussin‐Léveillée, Diego José Berlanga, Marina Martín‐Dacal, Miguel Ángel Medina Torres, Varun Kumar, , Julia Santiago

This study determines the structure of the plant receptor IGP1 bound to a cellulose-derived DAMP, revealing its mechanism for recognizing glycan patterns and initiating immune responses.

Chloroplastic ROS bursts initiate salicylic acid biosynthesis in plant immunity

Charles Roussin‐Léveillée, Méliane St‐Amand, Philippe Desbiens‐Fortin, Rosaëlle Perreault, Antoine Pelletier, Sabrina Gauthier, Faye Gaudreault‐Lafleur, Isabelle Laforest‐Lapointe, 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.
