Control of cytokinin autonomy in Phaseolus lunatus callus cultures

Creator:: Kim, Sang-Gu
Abstract:: The ability of N,N'-diphenylurea (DPU) to substitute for cytokininactive adenine derivatives in promoting callus growth of Phaseolus lunatus and Nicotiana tabacum has been examined. In general, DPU stimulated callus growth of P. lunatus at high concentrations and the growth of most callus tissues was irregular, while the response of tobacco...

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),...

Cytokinin oxidase activity from Phaseolus vulgaris L. cv. Great Northern callus tissues

Creator:: Chatfield, J. Mark
Abstract:: Cytokinin oxidase activity in callus tissues of Phaseolus vulgaris L. cv. Great Northern has been examined using an assay based on the oxidation of radioactively labeled N⁶ -(Δ² -isopentenyl) adenine (i⁶Ade) to adenine (Ade). Conditions for the quantitative extraction and assay of the enzyme have been established. The substrate specificity...

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...

Effects of washing and aging on the metabolism of red beet root slices

Creator:: Kolattukudy, Pappachan Ettoop
Abstract:: The rate of the C¹⁴0₂ release from glucose, specifically labeled with C¹⁴ at 1, 2, 3+4, and positions, was used to study the relative participation of pathways of glucose catabolism in red beet slices. Evidence was obtained which indicated that in mature red beets glucose was catabolized mainly via glycolysis-tricarboxylic...

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...
