TLDR
The results support the hypothesis that the active alcohol dehydrogenase isozymes are dimers composed of the six possible combinations of subunits coded by triplicate structural genes.Abstract:
The alcohol dehydrogenase zymogram phenotypes of 40 wheat strains, each possessing a distinctive chromosomal constitution, were determined. Genes involved in the production of alcohol dehydrogenase were located on the beta arm of chromosome 4A and on chromosomes 4B and 4D. The results support the hypothesis that the active alcohol dehydrogenase isozymes are dimers composed of the six possible combinations of subunits coded by triplicate structural genes.read more

TL;DR: Several recent hypotheses have proposed that the wide capabilities of allopolyploids are a direct biochemical consequence of their possession of two divergent diploid genomes which provides them with a multiplicity of enzymes relative to both diploids parents as well as a high proportion of novel enzymes.

TL;DR: The results of this study are consistent with the hypothesis that many of the duplicated structural genes of this species have diverged in structure and function subsequent to the origin of the polyploid wheats.
