ABA and ABA signaling mediate Arabidopsis stomatal response to CO2 via H2O2 and NO production

Key Points

• Stomatal response is mediated by ABA signaling, enhancing adaptability to CO2 levels and environmental changes.
• Key evidence shows that H2O2 and NO production are crucial for this signaling pathway.
• Analysis of plant physiological systems demonstrates the interaction between ABA, H2O2, and NO in stomatal regulation.
• This work highlights potential applications for improving plant resilience under climate change conditions.
