riboflavin/zea mays

Insect-protected corn hybrids containing event MON 863 protect corn plants against feeding damage from corn rootworm (Diabrotica), a major North American insect pest. Corn event MON 863 contains a gene that expresses an amino acid sequence variant of the wild-type Cry3Bb1 insecticidal protein from

When oxidized corn oil (100 nmol in terms of malondialdehyde/day/rat) was administered to a riboflavin-deficient rat, the body weight gain was markedly suppressed. However, when 20 microgram of riboflavin/day/rat was administered with the oxidized corn oil, reasonable growth and normal flavin levels

We investigated the effects of energy restriction on tissue riboflavin depletion and subsequent repletion of deficient tissues. Groups of male Sprague Dawley rats with average body weights between 268 and 275g were placed on energy-restricted diets consisting of 8g (31kcal or 130kJ) per day of a

Free flavins have been extracted from shoots of etiolated corn (Zea mays L., var. Burpee Snowcross) and from yeast cells and separated from other substances by absorption on resorcinol-formaldehyde resin and talc columns and by thin layer chromatography. Riboflavin was the only free flavin present.

The maize (Zea mays) classic kernel mutant defective kernel 33 (dek33) produced defective and occasionally viviparous kernel phenotype. In this study, we cloned Dek33 by positional cloning and found that it encodes the pyrimidine reductase in riboflavin biosynthesis. In dek33, a single base mutation

The production of riboflavin (vitamin B2) by Candida guilliermondii Wickerham cultivated on solar-containing medium was stimulated in the presence of corn oil (0.1 g%), arginine, phenylalanine (1 m mole/l) or CoSO4.7H2O (1000 micrograms/l). On the other hand, emulsifying agents strongly inhibited

Riboflavin (vitamin B₂) is the precursor of the flavin coenzymes flavin mononucleotide and flavin adenine dinucleotide. In Escherichia coli and other bacteria, sequential deamination and reduction steps in riboflavin biosynthesis are catalyzed by RibD, a bifunctional protein with distinct pyrimidine

1. AMPS Lyase which shows increased activity in both transplantable and primary hepatomas has been purified approximately 400-fold from both chow fed and basal fed rat liver. 2. The enzyme from basal fed rats shows subtle but significant differences from the enzyme from chow fed rats. Especially

In order to produce doubled-haploid maize plants tolerant of oxidative stress, in vitro microspore selection was carried out in anther culture with reactive oxygen species (ROS) progenitors such as paraquat, menadione, tert-butylhydroperoxide (t-BHP), and methionine combined with riboflavin. All the

Conditions for obtaining reproducible light-induced reduction of a b-type cytochrome in membrane fractions from coleoptiles of dark-grown Zea mays L. include a glucose-glucose oxidase system that lowers O(2) tension and generates H(2)O(2), substrate amounts of ethylenediaminetetraacetic acid which,

The present studies examined the effect of agents that induce peroxisomal and mitochondrial beta-oxidation on hepatic mitochondrial carnitine palmitoyltransferase (CPT) and peroxisomal carnitine acyltransferase [CPTs of Ramsay (1988) Biochem. J. 249, 239-245; COT of Farrell & Bieber (1983) Arch.

Shoots, roots, and seeds of corn (Zea mays L., cv. Michigan 500), oats (Avena sativa L., cv. Au Sable), and peas (Pisum sativum L., cv. Wando) were analyzed for their superoxide dismutase content using a photochemical assay system consisting of methionine, riboflavin, and p-nitro blue tetrazolium.
