| Abstract |
KEY MESSAGE:We identified a novel allele of the Vrn-A3 gene that is associated with an early flowering trait in wheat. This trait is caused by a cis-element GATA box in Vrn-A3. To identify novel flowering genes in wheat, we investigated days from germination to heading (DGH) in tetraploid wheat accessions. We found that the tetraploid variety Triticum turgidum L. ssp. dicoccum (TN26) harbors unknown genes that surpass the earliness effect of the early flowering allele Ppd-A1a harbored by TN28 (T. turgidum L. ssp. turgidum conv. pyramidale). Using recombinant inbred lines resulting from a cross between TN26 and TN28, we performed a quantitative trait locus (QTL) analysis for DGH. We identified a QTL for earliness in TN26 on chromosome 7AS, the chromosome on which Vrn-A3 is located. By sequence analysis for the Vrn-A3 locus in both TN26 and TN28, we identified a 7-bp insertion that included a cis-element GATA box sequence at the promoter region of the Vrn-A3 locus of TN26. Based on an expression analysis using sister lines for Vrn-A3, we suggest that the early flowering trait of TN26 was caused by the GATA box in Vrn-A3. In addition, we identified tetraploid wheat as a useful genetic resource for wheat breeding. |
