Some properties of diamine oxidase from Pisum sativum

Creator:: Yamasaki, Edith Fusayo
Abstract:: Partial purification of diamine oxidase from pea seedlings, Pisum sativum, was accomplished by homogenization of 8-10 day etiolated epicotyl tissue, followed by ammonium sulfate fractionation and DEAE Sephadex column chromatography. The preparation thus obtained was purified 50 fold. Some properties of this enzyme were investigated. A radio-tracer method was adapted...

Some aspects of an oxidative tryptophan decarboxylating enzyme in Pisum sativum

Creator:: Taylor, Frank Farnham
Abstract:: Three types of experiments were designed to further characterize the tryptophan decarboxylating enzyme of Reed and Crecelius (1967). 1) Light inhibition studies were made with etiolated pea seedlings to determine the in vitro response of the tryptophan decarboxylating enzyme. Assays of indoleacetic acid oxidase (IAA oxidase) and guaiacol-active pea seedling...

The visual response of the purple shore crab, Hemigrapsus nudus, to ionizing and non-ionizing radiation

Creator:: Jordan, Neil Michael
Abstract:: Bioelectric responses from the isolated eye of the purple shore crab were measured by the electroretinogram with stimulation by light from wavelengths of 250 to 800 nm, strontium-yttrium-90 beta radiation, 17.5 keV x-radiation, and 3-cm microwaves. Peak sensitivities to light stimulation were found at 350 and 500 nm. These peaks...

Analysis of cytochrome P-450 isozymes from rat liver and studies on the mechanism of induction

Creator:: Williams, David Edward
Abstract:: In order to determine the total number of cytochrome P-450 isozymes present in a given species following various treatments, mature male rats (Sprague-Dawley) were injected intraperitoneally with the classic mixed-function oxidase inducers phenobarbital (PB), pregnenolone- 16a-carbonitrile (PCN), 3-methylcholanthrene (3-MC), or the appropriate control vehicle. Hepatic microsomes were solubilized and P-450...

The lethal response of the roughskin newt, Taricha granulosa (Skilton), to ultraviolet-B radiation at three fluence rates

Creator:: Michaelis, Barbara
Abstract:: Roughskin newts, Taricha granulosa (Skilton), were exposed to UV-B (280-320nm), UV-A (321-380 nm), and visible radiation from fluorescent sunlamps (Westinghouse FS40) that were filtered with cellulose acetate film. UV-B controls were exposed to irradiation from sunlamps that were filtered with Mylar-D, a polyester film that effectively absorbed UV-B radiation while...

Cytokinin antagonists and antibiotics related to nalidixic acid : effects on Phaseolus and Nicotiana callus tissues

Creator:: Marsden, Katherine E.
Abstract:: The effects of five cytokinin antagonists on the growth of cytokinin-autonomous lines of Phaseolus lunatus cv. Kingston, Phaseolus vulgaris cv. Great Northern, and Nicotiana tabacum cv. Wisconsin 38 callus tissues have been compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines bearing the following N⁴ side chains, 4-n-pentyl- (ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...

Interaction of cytokinins and phenethylamines in cell-free enzyme systems and plant callus cultures

Creator:: Abdelnour-Esquivel, Ana
Abstract:: 1-Phenyl-3-(2-Thiazoly1)-2-Thiourea (PTTU), has been reported to inhibit dopamine-fi-hydroxylase (a copper-containing enzyme involved in the pathway of biosynthesis of adrenaline in animal systems). In the present study, PTTU has been shown to have cytokinin activity in the tobacco bioassay. The cytokinin activity of PTTU suggested that cytokinin-active N⁶-substituted adenine derivatives might...

Environmental constraints on the use of anion exchange membranes in dryland wheat

Creator:: Redman, Andrea Elizabeth
Abstract:: Lack of growing season precipitation and the temperate climate in north central Oregon pose challenges to growing spring wheat crops. Phosphate and sulfate fertilization can improve early growth of spring wheat in this region and soil testing aids in determining rates of fertilization. In this study, anion exchange membranes (AEM)...
