Gene Details:

• Gene ID: TraesCS4B02G020300
• Gene Symbol: TaGRP2
• Gene Name: glycine-rich RNA-binding protein
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• TaGRP2 inhibits transcript accumulation of the key flowering-promoting gene.
• During vernalization, nuclear-localized VER2 interacts with O-GlcNAc-modified TaGRP2 to relieve the repression on TaVRN1 transcript accumulation and to promote flowering in hexaploid winter wheat.
• TaGRP2 interacts with VER2 and regulates flowering in wheat.
• O-GlcNAc-mediated interaction between VER2 and TaGRP2 elicits TaVRN1 mRNA accumulation during vernalization in winter wheat.
• TaGRP2 protein accumulation in the nucleus and/or promotes TaGRP2 dissociation from TaVRN1, leading to TaVRN1 mRNA accumulation. Our data reveal a new mechanism for sensing prolonged cold in temperate cereals.
