Conditional overdominance at an alcohol dehydrogenase locus in yeast.
Documented examples of heterosis attributable to overdominance at specific protein-encoding gene loci have rarely been reported, the association of sickle cell hemoglobin with malarial resistance being the best documented example of this phenomenon. Here we report an example of overdominance that is temperature- and allyl alcohol-dependent and due to heterozygosity at the ADH1 locus, involving ...
متن کاملNitrogen Turnover and Assimilation during Regrowth in Trifolium subterraneum L. and Bromus mollis L.
Subterranean clover (Trifolium subterraneum L. cv Woogenellup) and soft chess grass (Bromus mollis L. cv Blando) were grown in monocultures with (15)NH(4)Cl added to the soil to study nitrogen movement during regrowth following shoot removal. Four clipping treatments were imposed. Essentially all available (15)N was assimilated from the soil prior to the first shoot harvest. Measurements of tot...
متن کاملElectrophoretic variability at the alcohol dehydrogenase locus in Drosophila melanogaster.
In crder to assess the extent of electrophoretic variation at the alcohol dehydrogenase locus in a natural population of Drosophila melanogmter KREITMAN ( 1980) screened ninety-six isochromosomal lines and two lines carrying “fast’’ thermostability variants of the enzyme using eight different conditions of acrylamide electrophoresis. Although he found no sdditional mobility variation within the...
متن کاملThe Genetics of Alcohol Metabolism: Role of Alcohol Dehydrogenase and Aldehyde Dehydrogenase Variants
The primary enzymes involved in alcohol metabolism are alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). Both enzymes occur in several forms that are encoded by different genes; moreover, there are variants (i.e., alleles) of some of these genes that encode enzymes with different characteristics and which have different ethnic distributions. Which ADH or ALDH alleles a person carri...
