Gene Details:

• Gene ID: Zm00001eb061930
• Gene Symbol: ZmbZIP29
• Gene Name: Zipper 29
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Identified a second hub coordinator, basic Leucine Zipper 29 (ZmbZIP29) that interacts with ZmABI19 to regulate O2 expression.
• Like zmabi19, ZmbZIP29 mutations resulted in a dramatic decrease of transcript and protein levels of O2 and thus a significant reduction of starch and storage proteins.
• ZmbZIP29 is an ABA-inducible TF and directly regulates O2 expression in the endosperm.
• Overexpression of ZmABI19 and ZmbZIP29 enhances grain filling and yield.
• ABA-induced phosphorylation of basic leucine zipper 29, ABSCISIC ACID INSENSITIVE 19, and Opaque2 by SnRK2.2 enhances gene transactivation for endosperm filling in maize.
