Abstract
Summary A study of α-amylase isozyme patterns from gibberellin-induced endosperms of wheat-alien genotypes (amphiploid, addition and substitution lines) resolved by flat-bed isoelectric focusing identified homoeoloci for α- Amy-1 (malt α-AMY-1 genes) on chromosomes 6H of Hordeum vulgare , 6RL of Secale cereale , 6R m of S. montanum and 6E of Agropyron elongatum . Homoeoloci for α- Amy-2 (green α-AMY-2 genes) were identified on chromosomes 7H ch L of Hordeum chilense , 7RL of Secale cereale , 7S b of Aegilops bicornis , 7U of Ae. umbellulata and 7EL of Agropyron elongatum . Analysis of mature grain β-amylase identified β- Amy-1 loci on chromosomes 4H of H . vulgare , 4H ch of H. chilense , 4S 1 of Ae. sharonensis and Ae. longissima and β- Amy-2 loci on chromosomes 5RL of S. cereale and 5U of Ae. umbellulata . These gene locations provide further evidence for the homoeology of the alien chromosomes with wheat and for the conservation of gene synteny among wheat and its relatives.
