High-molecular-weight glutenin subunits (HMW-GSs) are important seed storage proteins associated with bread-making quality in common wheat (Triticum aestivum L., 2n = 6x = 42, AABBDD). Variation in the Glu-A1x locus in common wheat is scare. Diploid Triticum monococcum ssp. monococcum (2n = 2x = 14, A^mA^m) is the first cultivated wheat. In the present study, allelic variations at the Glu-A1^mx locus were systematically investigated in 197 T. monococcum ssp. monococcum accessions. Out of the 8 detected Glu-A1^mx alleles, 5 were novel, including Glu-A1^m-b, Glu-A1^m-c, Glu-A1^m-d, Glu-A1^m-g, and Glu-A1^m-h. This diversity is higher than that of common wheat. Compared with 1Ax1 and 1Ax2*, which are present in common wheat, these alleles contained three deletions/insertions as well as some single nucleotide polymorphism variations that might affect the elastic properties of wheat flour. New variations in T. monococcum probably occurred after the divergence between A and A^m and are excluded in common wheat populations. These allelic variations could be used as novel resources to further improve wheat quality.
