Barley alpha-amylase variability influences the quality of barley grain in the brewing, feed and food industries. alpha-Amylase proteins are encoded by multigene families in cereals, and this study focused on the barley Amy32b gene. We identified coding region single nucleotide polymorphism (cSNP) and insertion/deletion variation in DNA sequences, which resulted in amino acid substitution and stop codon formation, respectively. The substitution affected the beta1 strand in domain C, whereas the stop codon removed the beta5 strand. Possible effects of these changes on the protein are discussed. A cSNP in the coding region of the Amy32b gene was used as a specific marker to map Amy32b loci on chromosome 7H.
