alpha carboxylase/zea mays

Herbicidal activity of aryloxyphenoxypropionate and cyclohexanedione herbicides (graminicides) has been proposed to involve two mechanisms: inhibition of acetyl-coenzyme A carboxylase (ACCase) and depolarization of cell membrane potential. We examined the effect of aryloxyphenoxypropionates

The susceptibilities of maize (Zea mays cv. Champ) and two graminicide-resistant grass species, Poa annua (annual meadow grass) and Festuca rubra (red fescue), to two aryloxyphenoxypropionates (quizalofop and fluazifop) and a cyclohexanedione (sethoxydim) graminicide were evaluated in leaf blades

A mutation (Acc1-S2) in the structural gene for maize (Zea mays L.) acetyl-coenzyme A carboxylase (ACCase) that significantly reduces sethoxydim inhibition of leaf ACCase activity was used to investigate the gene-enzyme relationship regulating ACCase activity during oil deposition in developing

3-Methylcrotonyl-CoA carboxylase has been purified to near homogeneity from maize leaves. The resulting preparations of 3-methylcrotonyl-CoA carboxylase have a specific activity of between 200 and 600 nmol.min-1.mg-1 protein, representing an approximately 5000-fold purification of the enzyme. The

A partially dominant mutation exhibiting increased tolerance to cyclohexanedione and aryloxyphenoxypropionate herbicides was isolated by exposing susceptible maize (Zea mays) tissue cultures to increasingly inhibitory concentrations of sethoxydim (a cyclohexanedione). The selected tissue culture

The genetic relationship between acetyl-coenzyme A carboxylase (ACCase; EC 6.4.1.2.) activity and herbicide tolerance was determined for five maize (Zea mays L.) mutants regenerated from tissue cultures selected for tolerance to the ACCase-inhibiting herbicides, sethoxydim and haloxyfop. Herbicide

Studies were made on the content, synthesis and degradation of acetyl-coenzyme-A carboxylase in JTC-25 - P3 cells, hepatocytes which can be maintained in a protein-free and lipid-free chemically defined medium. The addition of corn oil or fatty acid to the medium resulted in a decrease in the

Acetyl-CoA carboxylase [acetyl-CoA-carbon dioxide ligase (ADP forming), EC 6.4.1.2] is a biotin-containing enzyme catalyzing the formation of malonyl-CoA. The tissue distribution of this enzyme was determined for leaves of C(3)- and C(4)-plants. The mesophyll tissues of the C(3)-plants Pisum sativum

Maize (Zea mays L.) leaf acetyl-CoA carboxylase (ACCase) was purified about 500-fold by ammonium sulfate fractionation and gel filtration and blue Sepharose affinity and anion-exchange chromatography. Most ACCase activity (85%) recovered from the anion-exchange column was found in a highly purified

BACKGROUND Maternal dietary choices throughout preconception, pregnancy, and lactation irreversibly affect the development of fetal tissues and organs, known as fetal programming. Recommendations tend to emphasize reducing added sugars. However, the impact of maternal dietary free or bound fructose

The maximal activity and mRNA abundance of hepatic fatty acid synthase (FAS) and other lipogenic enzymes were investigated in rats meal-fed either a high fructose (F) or a high cornstarch (C) diet. The diet contained 50% F or C (g/100 g), casein (20%), cornstarch (16.13%), corn oil (5%), minerals

DAS-40278-9 maize (corn) plants have been genetically modified by the insertion of the aad-1 gene (aryloxyalkanoate dioxygenase), which confers tolerance to 2,4-dichlorophenoxyacetic acid (2,4-D) and aryloxyphenoxypropionate (AOPP) acetyl coenzyme A carboxylase (ACCase) inhibitors ("fop" herbicides)

Glucocorticoids (GCs) stimulate appetite, contributing to enhanced fat deposition. Our present study was conducted to determine whether GCs could evoke an appetite specifically for fat-rich diets in chicks. Chicks were subjected to a subcutaneous injection of corticosterone (CORT, 2mg/kg body

Thirty-six Angus-cross steers (667 ± 34.4 kg initial BW, 24.5 mo) were used to assess the impact of short-term glycerin or high-fructose corn syrup administration via drinking water on meat quality and marbling deposition. Steers blocked by BW (3 blocks) were assigned randomly to 1 of 3 drinking

1. Tryptophan was administered to rats under various nutritional conditions: fasted for 24 hr, fasted and refed with glucose or corn-oil, fasted and administered glycerol intramuscularly, and nonfasted. 2. The changes in the contents of glycolytic intermediates in the livers indicated that the
