Gene Details:

• Gene ID: TraesCS5A02G391700
• Gene Symbol: TaVRN1
• Gene Name: VERNALIZATION
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Identified the novel transcript VAS (TaVRN1 alternative splicing) as a non-coding RNA derived from the sense strand of the TaVRN1 gene only in winter wheat, which regulates TaVRN1 transcription for flowering.
• In hexaploid wheat, TaVRN1 is a cold-induced key regulator that accelerates floral transition.
• VAS, an alternative splicing transcript of TaVRN1, is induced specifically in winter wheat.
• The vernalization-induced long non-coding RNA VAS functions with the transcription factor TaRF2b to promote TaVRN1 expression for flowering in hexaploid wheat.
• TaVRT2 represses transcription of the wheat vernalization gene TaVRN1.
• TaVRT2 binds the CArG motif in the TaVRN1 promoter and represses its activity in vivo. In contrast, TaVRN2 does not bind the TaVRN1 promoter and has no direct effect on its activity, but it can enhance the repression effect of TaVRT2.
