Popis:	SummaryA 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 ofHordeum vulgare, 6RL ofSecale cereale, 6RmofS. montanumand 6E ofAgropyron elongatum. Homoeoloci for α-Amy-2(green α-AMY-2 genes) were identified on chromosomes 7HchL ofHordeum chilense, 7RL ofSecale cereale, 7SbofAegilops bicornis, 7U ofAe. umbellulataand 7EL ofAgropyron elongatum. Analysis of mature grain β-amylase identified β-Amy-1loci on chromosomes 4H ofH.vulgare, 4HchofH. chilense, 4S1ofAe. sharonensisandAe. longissimaand β-Amy-2loci on chromosomes 5RL ofS. cerealeand 5U ofAe. 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.
