โœฆ Synopsis

Genetic and cytogenetic locations of the structural genes for the NAD-dependent malate dehydrogenases have been studied. The mitochondrial form (mMDH) is coded for by a gene (mMdh) found at 62.6 on the third chromosome and included in Df(3R)R14, which includes 90C2-91A3 in the salivary gland chromosomes. Based on its inclusion within several J (Jammed; 2-41.0) deficiencies, the structural gene (cMdh) for the cytoplasmic form (cMDH) was determined to lie in region 31B-E, confirming the earlier finding of Grell. Flies lacking any cMDH activity (cMdhn-gamma 10069/Df(2L)J-der-27) were both viable and fertile.

Fifty-five wild-type stocks of Drosophila melanogaster have been screened for electrophoretic variants of NADP-dependent isocitrate dehydrogenase. Three stocks are polymorphic, and one is homozygous for a "fast" (toward the anode at pH 8.7) eleetrophoretic variant. Using the variants and the mapping
