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...

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...

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...

Effect of Substrate to Inoculum Ratio on Outcomes of In Vitro Rumen Fermentation Studies

Creator:: Remy, Jon D.
Abstract:: The objective of this study was to identify the varying effects of altering the rumen fluid: substrate ratio on the outcomes of in vitro rumen fermentation. In vitro fermentation is a useful tool for evaluating the energy value of feedstuffs and the effect of feed additives on Volatile Fatty Acid...

How Behavior, Physiology, and Ontogeny of Klamath Redband Trout Shape the Functionality of Habitats in a Landscape of Temperature Extremes

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...
