Resistance to soil-borne viruses as Soil-borne Wheat Mosaic Virus (SBWMV) has gained evident importance in wheat research and breeding. Very few varieties of bread and durum wheat are resistant to these viruses. Search for new sources of SBWMV is conducted worldwide and loci causing resistance have been described on the B and D genomes of tetraploid and hexaploid wheat. In the present study, a gene locus was identified on the A genome of Triticum monococcum and was successfully transferred to hexaploid wheat. In hexaploid wheat, it is expressed in a stable dominant manner. As this is the first SBWMV resistance gene located on the A genome, this locus is proposed as Sbm3.
