🚨🌱🦠 IT'S OUT!
Lead by Pedro Jiménez-Sandoval from Julia Santiago's group, we found that IGP1 is a DAMP receptor for the sugar cellotriose.
Interesting finding -> we found that DAMP recognition is a key immune layer for proper PAMP-triggered immunity signaling prior to PAMP detection.

Glycan recognition by a plant damage-sensing immune receptor
Pathogens target and degrade the extracellular matrix surrounding plant cells. A central question is how cell wall-derived damage-associated molecular patterns (DAMPs) are recognized and integrated to...

three biological replicates, as represented by dots of different colors, and letters
describe the statistically significant differences between populations determined by
one-way ANOVA followed by Tukey’s HSD test (P < 0.05).[Scale bars, 30µm in images
