Summary

Story summary

Researchers at the University of Warwick report that, in a study published in Nature Plants, plants can activate systemic immunity within three to four hours of infection, driven by jasmonate signaling, using a novel live-imaging tool.
The study shows jasmonate hormones initiate a quick alert, while salicylic acid responses follow later to sustain immunity.
This dual-phase strategy enhances plant resilience against pathogens.
