Genetics of Isozyme Polymorphisms in Carnation

Ten enzyme systems were studied for polymorphism in the parents and the prog-eny of crosses between carnation (Dlanthus caryophyllus) genotypes. The inheri-tance of nine isozyme loci was determined: three of them code for alanyl amino-peptidase (Aap-1, Aap-2, and Aap-3), two for glutamate-oxalacetate transaminase (Got-1 and Gof-3), and one for each of esterase (Est-2), phosphoglucolsomerase (Pgi-2), phosphoglucomutase (Pgm-2), and shiklmate dehydrogenase (Sdh-1). A 10th gene, Mmm, was proposed to be a modifier of the mobility of the mitochondrial malate dehydrogenase isozyme. The expression pattern of these 10 enzymes In different tissues and their subcellular localization was analyzed. The existence of 10 additional monomorphic isozyme genes was Inferred from our data: 6Pgd-1 and 6Pgd-2 from 6-phosphogluconate dehydrogenase, Adh-1 from alcohol dehydroge
