Comment
The Vrn-B3 locus (formerly known as Vrn-5 or Vrn-B4) is homologous to the Arabidopsis FT gene. The dominant Vrn-B3 allele in Hope has a retrotransposon insertion in the TaFT promoter (GenBank DQ890165). Transformation of winter wheat Jagger with the dominant Vrn-B3 significantly accelerated flowering. Different Hope seed sources were heterogeneous for this insertion. The retrotransposon insertion in the TaFT promoter is present in the CS (Hope 7B) (Yan et al., 2006). Vrn-B3 is completely linked to TaFT and 1 cM distal to Xabc158-7B on the region of 7BS proximal to the translocation with homoeologous group 5 (Yan et al., 2006).
