Harnessing plant redox networks and bacterial modulation for next-generation abiotic stress resilience in crops.

Abiotic stresses disrupt plant redox homeostasis by increasing reactive oxygen species (ROS), and the review links redox regulation with antioxidant defenses and bacterial modulation for stress resilience.

• Why it matters: Oxidative damage from excessive ROS reduces plant growth and productivity, while low ROS levels can function as signaling, creating a need to understand and tune redox control.
• What they did: The review synthesizes molecular mechanisms of plant redox balance, covering enzymatic and non-enzymatic antioxidants, phytohormone signaling, and plant growth-promoting bacteria (PGPB), alongside transcriptional, epigenetic, and redox regulatory networks.
• The result: It outlines how multi-omics and emerging synthetic biology and artificial intelligence tools could identify key components and engineer redox regulatory networks to support climate-resilient crops.
