Polymorfism of the glutenins and gliadins in emmer wheat from Spain

Pflüger L.A., Alvarez J.B., Martín L.M.

Emmer wheat (Triticum turgidum ssp. dicoccum Schrank) is hulled wheat that survives in marginal areas in Mediterranean region and that could be used as source of genes for wheat improvement. The storage protein composition of ninety-eight accessions of emmer wheat from Spain have been analysed by SDS-PAGE (HMW- and LMW-Gs) and A-PAGE (gliadins). For the HMW-Gs, four allelic variants were detected for the Glu-A1 locus; one of them has not previously described. For the Glu-B1 locus, three of nine alleles detected have not been found at now. High degree of variation has been found for the Glu-3 (LMW-Gs) and Gli-1 loci (gamma- and omega-gliadins).
