Gene Details:

• Gene ID: Zm00001eb050380
• Gene Symbol: ZmVp14 vp14 NCED1
• Gene Name: viviparous14
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The ZmVp14 gene was characterized from the ABA-deficient maize mutant Vp14 and is known to be regulated by salinity and osmotic stress
• Transient alkalinization of the leaf apoplast increases mRNA abundance of viviparous 14 (vp14).
• The present study demonstrates for the first time that the stomatal closure, elicited by the apoplastic alkalinization, is also due to a pHapo-mediated increase in the transcription of the NCED gene Vp14 in the leaf. ZmVp14 encodes the rate-limiting enzyme in ABA biosynthesis.
