MADS box genes control vernalization-induced flowering in cereals.


By comparing expression levels of MADS box transcription factor genes between near-isogenic winter and spring lines of bread wheat, Triticum aestivum, we have identified WAP1 as the probable candidate for the Vrn-1 gene, the major locus controlling the vernalization flowering response in wheat. WAP1 is strongly expressed in spring wheats and moderately… (More)
