title: The Inheritance of Enzyme Variants for Tyrosine Aminotransferase, Nadp-Dependent Malate Dehydrogenase, Nadp-Dependent Isocitrate Dehydrogenase, and Tetrazolium Oxidase in TETRAHYMENA PYRIFORMIS, Syngen 1.
abstract: The isozymic patterns of tyrosine aminotransferase, NADP malate dehydrogenase, NADP isocitrate dehydrogenase, and tetrazolium oxidase were examined by starch-gel electrophoresis in Tetrahymena pyriformis, syngen 1. The genetics of the alleles controlling these enzymes was studied through a breeding program. Each enzyme locus was shown to assort vegetatively, as do other loci in this organism. A detailed analysis of the assortment process for the tyrosine aminotransferase locus indicated that the rate of stabilization of heterozygotes into pure types was essentially identical to previously-reported rates for other loci.
