Gene Details:

• Gene ID: TraesCS1D02G353300
• Gene Symbol: TaSnRK1α1
• Gene Name: threonine protein kinase
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Sugar treatment induced TaSnRK1α1 protein accumulation while reducing TabHLH489 protein levels.
• TaSnRK1α1, the α-catalytic subunit of plant energy sensor SnRK1, interacted with and phosphorylated TabHLH489 to induce its degradation, thereby promoting wheat grain development.
• The TaSnRK1α1-TabHLH489 regulatory module integrates BR and sugar signalling to regulate grain length, presenting potential targets for enhancing grain size in wheat.
• Overexpressing TaSnRK1α1 or knocking out TabHLH489 both promotes wheat grain development and increases grain weight.
