7 ergosterol/トウモロコシ

A putative 8,7SI (sterol 8,7-isomerase) from Zea mays, termed Zm8,7SI, has been isolated from an EST (expressed sequence tag) library and subcloned into the yeast erg2 mutant lacking 8,7SI activity. Zm8,7SI restored endogenous ergosterol synthesis. An in vitro enzymatic assay in the corresponding

The potential for toxic interactions between ergosterol biosynthesis-inhibiting fungicides (EBIFs), used in U.S. agriculture or clinically, and phosphorothioate insecticides was assessed in adult male rats and adult male bobwhite quail (Colinus virginianus) by measuring inhibition of plasma butyryl

We report the characterization of a higher-plant C-24 sterol methyltransferase by yeast complementation. A Zea mays endosperm expressed sequence tag (EST) was identified which, upon complete sequencing, showed 46% identity to the yeast C-24 methyltransferase gene (ERG6) and 75% and 37% amino acid

Biochemical biomarkers, such as inhibition of serum butyryl cholinesterase (BuChE) and brain acetyl cholinesterase (AChE), have been useful in studies of interactive effects of pesticides in birds. Examples of interactions due to increased activation or decreased detoxication are reviewed. Studies

The kinetics of fumonisin B₁ (FB₁) biosynthesis have been examined in ears of four botanical varieties Zea mays var. indentata, Zea mays var. indurata, Zea mays var. saccharata and Zea mays var. everta inoculated with F. verticillioides isolates at silking stage. The level of mycotoxin accumulated

Fungi of the genus Fusarium are common fungal contaminants of maize and are also known to produce mycotoxins. Maize that has been genetically modified to express a Bt endotoxin has been used to study the effect of insect resistance on fungal infection of maize grains by Fusarium species and their

Biological treatments are considered an environmentally option to clean-up polluted soil with polycyclic aromatic hydrocarbons (PAHs). A pot experiment was conducted to comparatively evaluate four different strategies, including natural attenuation (NA), mycoaugmentation (M) by using Crucibulum
