Abstract:
The relative activities of alcohol dehydrogenase isozymes have been studied during the development of the endosperm and scutellum of heterozygous Adh1F/Adh1Smaize kernels. The products of the Adh1Fallele are found earlier than the products of the Adh1Sallele in both the scutellum and the endosperm. A second gene (Adhr)which controlsthe activity level of ADH is active in the scutellum only. The AdhrNallele specifies increase in the relative activity of the Adh1Sproducts from 26 to 38 days after pollination. This increase is prevented by the AdhrLallele which is dominant. These results ar discussed on the basis of the "limited factor" hypothesis proposed recently by Schwartz (1971) for the regulation of the Adh1gene in maize. © 1971 Springer-Verlag.
