Key Points

  • The research aims to elucidate the dynamics and crosstalks of H2S and H2O2 signaling in plant stress responses.
  • Used a disposable SERS sensing patch for real-time monitoring.
  • Combined sensor data with partial least squares discriminant analysis (PLS-DA).
  • Focused on tomato and rice plants.
  • Achieved a classification accuracy of stress types exceeding 95%.
  • Developed a non-destructive and highly sensitive detection system for stress signals.
  • Demonstrated a complex cross-regulation mechanism between sulfur and hydrogen peroxide signaling.

Abstract

in tomatoes and rice both had specific dynamic change rules, and there was a complex cross-regulation mechanism between them. By combining sensor data with partial least squares discriminant analysis (PLS-DA), the classification accuracy of stress types exceeds 95%. This non-destructive and highly sensitive detection system can provide real-time dynamic data of stress signals, bringing a breakthrough to the in-situ monitoring of plant physiological states.
