WebApr 14, 2024 · In this regard, thiols represent the largest part of the overall antioxidant pool . Thiols act as electron acceptors; hence it can efficiently reduce and scavenge ROS . Catalase is a crucial antioxidant enzyme; it decomposes hydrogen peroxide into oxygen and water and sustains the cellular redox homeostasis [73,74]. WebMar 14, 2024 · Hydrogen peroxide (H 2 O 2) is an important signaling molecule in plant developmental processes and stress responses.However, whether H 2 O 2-mediated signaling crosstalks with plant hormone signaling is largely unclear.Here, we show that H 2 O 2 induces the oxidation of the BRASSINAZOLE-RESISTANT1 (BZR1) transcription factor, …
