Gene Details:

• Gene ID: Zm00001eb009250
• Gene Symbol: ZmMKK9 MKK9
• Gene Name: mitogen-activated protein kinase kinase 9
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• A high-temperature sensitive (hts) mutant from the ethyl methane sulfonate (EMS)-induced maize (Zea mays) mutant library that is linked to a single base change in MITOGEN-ACTIVATED PROTEIN KINASE 20 (ZmMPK20).
• ZmMKK9 phosphorylated ZmMPK20 and enhanced the inhibitory effect of ZmMPK20 on ZmRIN2 degradation.
• ZmMKK9 and ZmRIN2 play negative regulatory roles in high-temperature–induced stomatal opening.
• The ZmMKK9–ZmMPK20–ZmRIN2 cascade negatively regulates high-temperature–induced stomatal opening and balances water loss and leaf temperature, thus enhancing plant thermotolerance.
• ZmMKK9 also plays a role in high-temperature–mediated stomatal movement and contributes to plant.
