abstract：:beta-Glucosidase (beta-D-glucoside glucohydrolase, E.C. 3.2.1.21, beta-Glu) isozyme variants were studied in a large number of inbred lines, crosses, and races of maize (Zea mays L.). The pattern of Mendelian inheritance demonstrated for beta-GLU variants indicated that they are under nuclear gene control. Twenty-two ...

abstract：:Ade-H and ade-I are two auxotrophic mutants of Chinese hamster ovary (CHO-K1) cells which specifically require adenine as the purine source to grow. The enzymatic defects of these mutants were examined in cell-free extracts. It was found that ade-H did not have any detectable adenylosuccinate synthetase activity and a...

abstract：:Evidence is presented to show that the Sh locus specifies sucrose synthetase in the developing endosperm of maize. The sh/sh/sh endosperm possesses less than 10% sucrose synthetase activity as compared to the normal Sh/sh/sh endosperm. The residual enzyme activity in five independently derived mutant genotypes is attr...

abstract：:The ratio of cellular RNA and protein content is about 1:1 between phylogenetically diploid and tetraploid species of the teleost family Cyprinidae, but is roughly in proportion to ploidy in species of the teleost order Isospondyli. Enzyme activities do not unequivocally comply with this scheme. These findings are dis...
