Characteristics Of Binding Of Interleukin-1 To Yt.Nci Cells, Susan Catherine Speziale

Masters Theses

Interleukin-1 (IL-1) demonstrated a concentration dependent, specific binding to the human, large granular lymphocyte cell line, YT.NCI with a dissociation constant of 0.2 nM. There were approximately 500 IL-1 receptors/cell.

IL-1 binding to YT.NCI cells could be inhibited by unlabeled-IL-1 and the plant lectins, WGA and Con A. Lectin inhibition of IL-1 binding could be completely abrogated by exposing lectins to specific simple sugars prior to the addition of ligand.

Tunicamycin, an inhibitor of glycosylation, decreased IL-l binding to YT cells in a reversible, time- and concentration-dependent manner.

These observations suggest that glycosylation of cell surface proteins may be important …

Quantitative Studies On Nodulation Competition Of Two Strains Of Bradyrhizobium Japonicum And Its Biological Control With A Bacteriophage, Jin Xiong

Masters Theses

Interstrain competition of Bradyrhizobium japonicum for nodulation of soybean (Glycine max) presents a serious problem to the field commercial inoculation practice. The more efficient, introduced strains are often outcompeted by the less efficient, indigenous strains. This study was conducted to determine if the competition could be effectively controlled by the massive introduction of a more efficient strain and/or the large scale reduction of a indigenous strain by the application of a bacteriophage specific to the indigenous one.

B. japonicum strain 61A123, common in Midwestern U.S. soils, and strain USDA110, representative of the strains used in commercial inocula, were chosen for …

Callus Formation And Differentiation In Embryos Of The Coconut Palm (Cocos Nucifera L.), Jyoti Mangesh Desai

Masters Theses

Embryos of Cocos nucifera L. were allowed to develop on various agar based, plant tissue culture media. Environmental conditions, temperature, light intensity levels and photoperiod were regulated throughout the period of the experiment. The anatomy of commercially available embryos (excised from the "seed") and tissues that developed in culture (calli, roots and leaves) was determined. Prepared slides and tissues obtained in culture were photographed and printed. Callus, root and shoot formation were successful. However, "embryoids" which would have eventually led to free living plantlets were not obtained during this study. Successful regeneration of plantlets in culture would require improved techniques.
