Gene Details:

• Gene ID: TraesCS2D02G499200
• Gene Symbol: TabHLH489
• Gene Name: helix–loop–helix (bHLH) transcription factor 89
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Identified a wheat atypical basic helix–loop–helix (bHLH) transcription factor, TabHLH489, which is tightly associated with grain length through genome-wide association study and map-based cloning.
• Knockout of TabHLH489 and its homologous genes resulted in increased grain length and weight, whereas the overexpression led to decreased grain length and weight.
• Importantly, natural variations in the promoter region of TabHLH489 affect the TaBZR1 binding ability, thereby influencing TabHLH489 expression.
• The TaSnRK1α1-TabHLH489 regulatory module integrates BR and sugar signalling to regulate grain length, presenting potential targets for enhancing grain size in wheat.
