Story summary

Researchers at the Salk Institute found that Arabidopsis thaliana prioritizes immune response over growth after drought, a phenomenon called “Drought Recovery-Induced Immunity” (DRII).
Immune activation occurs within 15 minutes of rehydration and is also seen in tomatoes, indicating a shared mechanism in crops.
The study highlights that recovery is vital for plant resilience, with potential benefits for crop engineering.
