Immunoelectrophoretic techniques used for systematic investigation

Creator:: Lockwood, Lloyd James
Abstract:: Immunotaxonomic studies have largely been based on serology in which either one of two parameters has been used for establishing relationships: (1) the number of precipitin arcs formed on Ouehterlony plates, or (2) the total amount of precipitin resulting from reactions with a standard antiserum. Recognizing the restrictions of both...

Effects of physiological state upon nitrosoguanidine-mediated allelic recombination in Saccharomyces cerevisiae

Creator:: Buettner, Michael John
Abstract:: Saccharomyces cerevisiae strain XS-380, a. heteroallelic diploid strain, carries six genetically analyzed loci on the left arm of chromosome VII. Nitrosoguanidine (NMG) at low concentrations was observed to cause allelic recombination (either mitotic recombination or gene conversion) of the heteroallelic loci with low lethality. The NMG-inducible heteroallelic system was used...

Evaluation of four quality factors in a selected winter x spring wheat cross (Triticum aestivum Vill., Host)

Creator:: Schumaker, Karen Sue
Abstract:: The nature of the genetic variation associated with a cross involving winter and spring wheat parents for four quality factors was evaluated. Yamhill, a soft white winter wheat, and Inia 66, a hard red spring wheat, were selected as parents for this study. They represented distinctly different phenotypes for the...

Deoxyribonucleic acid hybridization and plasmid studies in the genus Lactobacillus

Creator:: Sriranganathan, Nammalwar
Abstract:: Using thermal denaturation methodology, the nucleic acid base composition of deoxyribonucleic acid (DNA) isolated from type, neotype and stock strains of Lactobacillus species was determined. The genus was found to be heterogeneous in base composition, ranging from 33.1 to 50.0 moles % guanine plus cytosine (GC). Genus members fell into...

Cell division and DNA synthesis in Saccharomyces cerevisiae following nutritional shiftup

Creator:: Jacobson, Gunnard Kenneth
Abstract:: Nutritional shift-up experiments have revealed many important macromolecular interactions in bacteria. It has been shown that RNA synthesis can be dissociated from protein and DNA synthesis. The rates of protein synthesis were found to be, at a given temperature, strictly dependent on the numbers of mature ribosomes present. DNA synthesis...

Meiotic chromosome behavior in two tall fescue (Festuca arundinacea Schreb.) genotypes and their sterile hybrid

Creator:: Vásquez, Raul Moreno
Abstract:: Two diverse genotypes of tall fescue, Festuca arundinacea Schreb (6X=42), with normal fertility, produced upon intercrossing, vigorous F ₁ hybrid plants that were sterile. One parent genotype (P₁) was from P. I. 234-906, introduced from Switzerland and the other (P₉) was an introduction from Turkey, P. I. 174-209. P₁ and...

Studies on host range, fine structure, and nucleic acids of lactic streptococcus bacteriophages

Creator:: Nyiendo, Joanne Annette
Abstract:: The most frequent cause of insufficient acid production during fermentation of dairy products is bacteriophage infection of lactic starter cultures. Previously, efforts to minimize this problem have dealt primarily with the host range relationships of the viruses and susceptibility patterns of the lactic streptococci. This study was undertaken to characterize...

A partial characterization of the deoxyribonucleic acid found in the thoracic muscles of the tobacco hornworm moth (Manducta sexta)

Creator:: Hinds, Thomas Richard, 1944-
Abstract:: The DNAs (deoxyribonucleic acids) of the thoracic tissue of the tobacco hornworm, Manducta sexta, were studied by physical and chemical means. The adult moth was considered to be fully formed two days after emergence from the pupal case, as indicated by its ability to fly and the integrity of the...

Influence of aluminum toxicity in intergeneric crosses of wheat and rye

Creator:: Lopez-Benitez, Alfonso
Abstract:: A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...
