Gene Details:

• Gene ID: Zm00001eb143690
• Gene Symbol: ZmVP1
• Gene Name: Zea mays VIVIPAROUS1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Zea mays VIVIPAROUS1 (ZmVP1) is a key regulator of seed maturation and seed vigor; it binds to the RY motif and regulates relevant gene expression.
• ZmVP1 regulates ZmPIMT2 expression during seed maturation.
• We demonstrate here that ZmPIMT2 is specifically expressed in maize (Zea mays) embryos and its expression is regulated by ZmVIVIPAROUS1 (ZmVP1) during seed maturation.
• To investigate whether ZmPIMT2 is regulated by ZmVP1 in vivo, the mRNA level of ZmPIMT2 in embryos from 20 and 32 DAP seeds was compared between the vp1-R mutant and its NS (previously characterized in our lab.
• ZmVP1 binds to the RY motif in the ZmPIMT2 promoter and regulates its expression during seed maturation.
• Maize VIVIPAROUS1 Interacts with ABA INSENSITIVE5 to Regulate GALACTINOL SYNTHASE2 Expression Controlling Seed Raffinose Accumulation.
