Gene Details:

• Gene ID:
• Gene Symbol: ZmWUS1-B
• Gene Name: WUS1 protein
• Genome:
• Species: Zea mays

Functional Descriptions:

• ZmWUS1-B is controlled by a spontaneously generated novel promoter region that dramatically increases its expression and alters patterning and development of young ears.
• Overexpression of ZmWUS1-B is caused by a unique enhancer region containing multimerized binding sites for type B RESPONSE REGULATORs (RRs), key transcription factors in cytokinin signaling.
• In combination with dual-luciferase assays in maize protoplasts, our analysis reveals that AGATAT motifs have an additive effect on ZmWUS1-B expression, while the distance separating AGATAT motifs does not appear to have a meaningful impact, indicating that the enhancer activity derives from the sum of individual CREs.
• These results also suggest that in maize inflorescence development, there is a threshold of buffering capacity for ZmWUS1 overexpression.
