    Notes: Summary Four zones of enzymatic activity for glutamate oxaloacetate transaminase (GOT) were found in apple tissue. A dimeric gene, GOT-1, determining the fastest migrating zone, was identified. Six alleles were found, including a near null allelle which produced detectable heterodimeric bands but not homodimeric bands. A marked deficit or absence of certain geno-types in all backcrosses and in some crosses between unrelated varieties was attributed to the close linkage (r=0.02±0.005) of GOT-1 with the incompatibility S locus. GOT-1 was also closely linked with the isocitrate dehydrogenase locus IDH-1 (0.03±0.01). Proposed incompatibility genotypes for four cultivars, and the linked GOT-1 alleles are ‘Cox’: S 1 b/S 2 d, ‘Idared’: S 3 a/S 4 c, ‘Fiesta’: S 3 a/S 2 d and ‘Kent’: S 3 a/S 1 b.

    Genetics of superoxide dismutase in apple (1997)

    Notes: Abstract  Four zones of superoxide dismutase (SOD), activity were detected in apple. Genetic studies confirmed the presence of three genes Sod-1, Sod-3 and Sod-4 with three, two and two alleles respectively, including one null allele. One of these genes, Sod-1, was found to be loosely linked to Prx-2 and Prx-3. The Sod-1a allele predominated in all the three groups studied, cultivars, rootstocks and Malus species. The distinct achromatic bands produced by SOD after electrophoresis facilitate its important role with peroxidase (PRX), glutamate oxalacetate transaminase (GOT) and phosphogluconate dehydrogenase (PGD) in the discrimination of apple cultivars.
