Gene Details:

• Gene ID: Zm00001eb107190
• Gene Symbol: ZmCPK37 ZmCBL3 ZmCDPK37 ZmCDPK7 cdpk32
• Gene Name: calcium dependent protein kinase32
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The maize inbred and hybrid lines overexpressing ZmCPK35 and ZmCPK37 exhibited enhanced tolerance and increased yield under drought conditions.
• Overexpression of ZmCPK35 and ZmCPK37 increased S-type anion currents in guard cells and promoted stomatal closure in responses to ABA and Ca2+, which improved maize drought tolerance.
• ZmSLAC1 activated by ZmCPK35 and ZmCPK37 was able to mediate both NO3- and Cl- currents.
• We found that two Ca2+-dependent protein kinases ZmCPK35 and ZmCPK37 were expressed in maize guard cells and localized on the plasma membrane.
• Mutation of ZmSLAC1 and ZmCPK37 impaired ABA-activated S-type anion currents in maize guard cells, while the S-type anion currents were increased in the guard cells of ZmCPK35- and ZmCPK37-overexpression lines. Electrophysiological characterization in maize guard cells and Xenopus oocytes indicated that ZmCPK35 and ZmCPK37 could activate ZmSLAC1-mediated Cl- and NO3- currents.
