Two highly variable enzyme systems of glucosephosphate isomerase (GPI) and phosphoglucomutase (PGM) were used to investigate the parentages of grape cultivars. Of 35 parent/offspring combinations that we investigated, 30 combinations gave alleles in the offspring which were presented in the reported parents, whereas 5 combinations gave alleles in the(More)
Methionine was subjected to a flame-induced reaction in water or in an aqueous formic acid solution by using a hydrogen (50%)-oxygen (50%), hydrogen (87%)-oxygen (13%) and hydrogen diffusion flame. Besides the already-known stepwise oxidation by a hydroxyl radical, the contribution of a hydrogen atom from the flame to the reaction was recognized when the(More)
Multiple isoforms of superoxide dismutase (SOD) occurred in grape following an electrophoretic analysis of 75 grapevine accessions. Three activity zones were resolved, and were designated as Sod-1, Sod-2 and Sod-3 in order of their anodal electrophoretic mobility. For the banding pattern and staining intensity, no differences were observed in both ploidy(More)
