Chemical type

• Reactive oxygen species (ROS)
• Signaling molecule

^[1]

• Reactive oxygen species (ROS)
• Redox-active signalling molecule

^[2]

• Oxidizing agent

^[3]

Key properties

• High permeability via XIPs, PIPs (e.g., PIP2;1), and TIPs
• Negligible water permeability in some XIPs

^[2]

• Decomposes to highly reactive •OH radicals in catalytic systems
• Effective in acidic conditions for pollutant oxidation
• Non-selective reactivity for breaking chemical bonds in organics

^[3]

• Redox signaling in stress responses (e.g., drought, salinity, hypoxia)
• Triggers stomatal closure via ABA pathways
• Involved in pathogen defense and innate immunity

^[1]

• Exogenous ROS treatment to trigger redox signalling
• Positive control for symplastic ROS detection
• Investigation of ROS–Ca²⁺ signalling crosstalk
