Gene Details:

• Gene ID: Zm00001eb200350
• Gene Symbol: ZmCCaMK ccamk1 CCaMK ccamk1
• Gene Name: calcium/calmodulin dependent protein kinase1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmBSK1 localizes in plasma membrane, interacts with calcium/calmodulin (Ca2+/CaM)-dependent protein kinase (ZmCCaMK), and phosphorylates ZmCCaMK. Ser-67 is a crucial phosphorylation site of ZmCCaMK by ZmBSK1.
• Drought stress enhances not only the interaction between ZmBSK1 and ZmCCaMK but also the phosphorylation of Ser-67 in ZmCCaMK by ZmBSK1. Furthermore, Ser-67 phosphorylation in ZmCCaMK regulates its Ca2+/CaM binding, autophosphorylation and transphosphorylation activity, and positively affects its function in drought tolerance in maize.
• In maize, ZmCCaMK phosphorylating NAC84 regulates ABA-induced antioxidant defense and drought stress.
• Calcium and ZmCCaMK are involved in brassinosteroid-induced antioxidant defense in maize leaves.
• Our results also showed that ZmCCaMK and H2O2 influenced each other. These results indicate that Ca2+ works together with ZmCCaMK in BR-induced antioxidant defense, and there are two positive feedback loops between Ca2+ or H2O2 and ZmCCaMK in BR signaling in maize.
