Gene Details:

• Gene ID: Zm00001eb301570
• Gene Symbol: Opaque2 o2 ZmbZIP1
• Gene Name: opaque endosperm2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The transcription factors ZmNAC128 and ZmNAC130 coordinate with Opaque2 to promote endosperm filling in maize.
• The first TF identified related to zein biosynthesis was Opaque2 (O2), which directly regulates the expression of 22-kD α-zein through the recognition of the O2-box cis-element in its promoter.
• Opaque2 (O2) are transcription factors important for cell patterning and nutrient storage in maize (Zea mays) endosperm.
• Three key transcription factors, NAKED ENDOSPERM1 (NKD1), NKD2, and Opaque2 (O2), play important roles in maize endosperm cellular development and storage material accumulation.
• A SnRK1-ZmRFWD3-Opaque2 Signaling Axis Regulates Diurnal Nitrogen Accumulation in Maize Seeds.
• The transcription factors ZmNAC128 and ZmNAC130 coordinate with Opaque2 to promote endosperm filling in maize.
