uridine diphosphate/옥수수

The growth of corn (Zea mays) roots and barley (Hordeum vulgare) coleoptiles is sensitive to the presence of external d-glucosamine and d-galactose. In order to investigate this effect, tissues were fed the radioactive monosaccharides at concentrations that ranged from those that were strongly

Microsomal membrane preparations from maize (Zea mays L., inbred A636) endosperm cultures contained enzymes that transferred sugar moieties from uridine diphosphate-N-acetylglucosamine, guanosine diphosphate-mannose, and uridine diphosphate-glucose to dolichol-phosphate. These enzyme activities were

Rats were fed corn oil-free or corn oil-containing diets for 4 weeks to determine their effect on the competition between glucuronidation and sulfation in phenol and its para substituents. The activities of uridine diphosphate-glucuronyltransferase (UDPGT) on chemicals were enhanced with a 12% corn

The objective of this research was to examine the time- and dose- dependent disturbances in the hypothalamic-pituitary-thyroid (HPT) axis of adult male rats administered a potent coplanar (non-ortho) PCB, 3,3',4,4',5-pentachlorobiphenyl (PCB 126). Adult male Sprague-Dawley rats were administered a

The mode of action of the herbicide 3,7-dichloroquinolinecar-boxylic acid (quinclorac) was examined by measuring incorporation of [14C]glucose, [14C]acetate, [3H]thymidine, and [3H]uridine into maize (Zea mays) root cell walls, fatty acids, DNA, and RNA, respectively. Among the precursors examined,

The effect of inorganic phosphate (Pi) on sucrose-phosphate synthase (SPS) activity was determined for the enzyme from five plant species (Nicotiana tabacum L., Spinacia oleracea L., Triticum aestivum L., Zea mays L., Glycine max L.) using two assay methods. The assay method based on determination

Sex determination in maize involves the production of staminate and pistillate florets from an initially bisexual floral meristem. Pistil elimination in staminate florets requires jasmonic acid signaling, and functional pistils are protected by the action of the silkless 1 (sk1) gene. The sk1 gene

d-Glucosamine-1-(14)C was rapidly taken up from aqueous solution by both excised bean (Phaseolus vulgaris) and corn (Zea mays) root tips. The labeled glucosamine did not accumulate in the tissues, however, but was metabolized to N-acetyl-d-glucosamine, N-acetyl-d-glucosamine phosphates, and uridine

Although Lepomis species are abundant in a wide variety of habitats throughout North America and could serve as potentially valuable biomonitoring tools, few studies have examined the induction of pollutant biomarkers in this genus. We hypothesized that the induction of cytochrome P-450 1A (CYP1A),
