Gene Details:

• Gene ID: Zm00001eb232260
• Gene Symbol: ZmMPK7|ZmMPK14
• Gene Name: MAP kinase14
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Abscisic acid and hydrogen peroxide induce a novel maize group C MAP kinase gene, ZmMPK7|ZmMPK14, which is responsible for the removal of reactive oxygen species.
• Exogenous abscisic acid (ABA) and hydrogen peroxide (H2O2) induced calcium-dependant transcription of ZmMPK7|ZmMPK14. Induction of this gene in response to ABA was blocked by several reactive oxygen species (ROS) manipulators such as imidazole, Tiron, and dimethylthiourea (DMTU).
• This result indicates that endogenous H2O2 may be required for ZmMPK7|ZmMPK14-mediated ABA signaling. Expression of ZmMPK7|ZmMPK14 in Nicotonia tobaccum caused less H2O2 to accumulate and alleviated ROS-mediated injuries following submission of the plants to osmotic stress.
• Finally, we have shown that the ZmMPK7|ZmMPK14 protein localizes in the nucleus. These results broaden our knowledge regarding plant group C MAPK activity in response to stress signals.
