Abstract

Hydrogen peroxide (H2O2) has an essential role in plant stress and immunity responses, but how H2O2 regulates these processes remain unclear. Recent findings showed that H2O2 enhances resistance in infected or distal tissues by fine-tuning the post-translational modifications (PTMs) of two key transcription factors, basic helix-loop-helix 25 (bHLH25) and CCA1 HIKING EXPEDITION (CHE), within plant immunity signaling pathways.
