Gene Details:

• Gene ID: TraesCS1B02G326500
• Gene Symbol: DUO-B1
• Gene Name: AP2/ERF domain-containing protein
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• DUO-B1 suppresses cell division and promotes the expression of BHt/WFZP, whose mutations could lead to branched ‘miracle-wheat’.
• Mutations of DUO-B1 lead to mild supernumerary spikelets, increased grain number per spike and, importantly, increased yield under field conditions without affecting other major agronomic traits.
• Using Brachypodium distachyon as a wheat proxy, we identified DUO-B1, encoding an APETALA2-ethylene response factor (AP2-ERF) transcription factor, regulating spike inflorescence architecture in bread wheat.
• DUO-B1 suppresses cell division and promotes the expression of BHt-WFZP, whose mutations could lead to branched miracle-wheat.
