Physical properties and genetic studies of cryptic plasmids discovered in plant pathogenic pseudomonads

Creator:: Curiale, Michael Steven
Abstract:: Six plant pathogenic isolates of Pseudomonas syringae pv. glycinea, the causal agent of bacterial blight of Glycine max (L.) Merrill, and one isolate of P. syringae pv. phaseolicola, the causal agent of halo blight of Phaseolus vulgaris L., have been examined for the presence of circular duplex deoxyribonucleic acid (DNA)....

Genomic comparisons of seed-transmissible and non-seed-transmissible strains of cucumber mosaic virus

Creator:: Ried, Jeffrey L.
Abstract:: A sensitive assay for the analysis of contaminating segments in pseudorecombinants constructed from a seed-transmissible (CVM-Pg) and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic virus was developed using partial RNase T₁ digestion. Isolated genomic RNA segments produced unique digestion patterns when 3'- end labeled, treated with RNase T₁, and subjected...

Regulation of phosphofructokinase by reversible inactivation

Creator:: Zhao, Zhizhuang
Abstract:: The interaction of skeletal muscle phosphofructokinase with a variety of acidic proteins including calmodulin and troponin C and with nucleic acids (RNA and DNA) is manifest in a reversible, time-dependent loss of catalytic activity. The inactivation is affected by a number of factors. Substrates (fructose-6-phosphate and ATP), positive effectors (fructose-2,6-bisphosphate,...

Suppression of yolk polypeptide gene expression in Drosophila melanogaster by sodium butyrate treatment

Creator:: Fairfax, Carolyn S.
Abstract:: Current evidence suggests that temporal regulation of gene expression in eucaryotic organisms relies primarily upon localized structural modifications of chromatin. One possible means of changing chromatin structure is through varying the level of acetylation of the histone proteins. Sodium butyrate has been found to inhibit the activity of histone deacetylase...

Antibacterial activities in the salivary glands of female mosquitoes Aedes aegypti

Creator:: Deng, Lanqian
Abstract:: Antibacterial activities in the salivary glands of female mosquitoes Aedes aegypti were investigated in this study. The mean salivary bacteriolytic activity, during a period of 14-day of female mosquitoes exposed to five different concentrations of Gram-positive bacteria Micrococcus lysodeikticus in the sucrose meal, was detected by a lysoplate method. A...

Characterization of the role of the 3' noncoding region of turnip yellow mosaic virus RNA

Creator:: Tsai, Ching-Hsiu
Resource Type:: Dissertation

Effects of nucleosomes on transcription by polymerase I in a reconstituted system

Creator:: Georgel, Philippe, 1961-
Abstract:: The aim of this study was to gain more information about the interactions between DNA and the histone octamer during the process of transcription. This work used a pUC8 plasmid derivative that contained the core promoter region of the RNA polymerase I of Acanthamoeba castellanii, placed upstream of four repeats...

New methods for sedimentation and diffusion analysis of macromolecular structure

Creator:: Demeler, Borries
Abstract:: Methods are presented to acquire data from analytical ultracentrifugation experiments by computer using the absorption optical scanning system of the Beckman Model-E ultracentrifuge. A computer program was written which analyzes sedimentation velocity experiments by the van Holde - Weischet method and by the second moment method. The van Holde -...
