Damage on plants activates Ca2+-dependent metacaspases for release of immunomodulatory peptides The plant immune system is activated when a protease translates physical damage into a defense response.

Simon Stael from SLU-Uppsala is showing us a new story on how #proteolysis regulates wound response. See Simon's ground-breaking work on wound response: www.science.org/doi/10.1126/... #plantproteolysis2025 #N_terminomics
