A gene (Adhrr) which controls the activity of alcohol dehydrogenase in the scutellum of maize has been found. This gene is not allelic to the Adh1 locus, which specifies the charge of the enzyme molecule and hence its migration rate. The two genes are linked and located about 17 crossover units apart. The AdhrN allele specifies equal activities of both the Adh1S and Adh1F products. The AdhrL allele gives lower activities of the Adh1S products only and operates in both the cis and the trans configurations.
