Actinoplanes Philippinensis: Effect of Carbon Sources on Zoospore Production

Actinoplanes Philippinensis: Effect of Carbon Sources on Zoospore Production

Date: May 1968
Creator: White, Olivia
Description: Actinomycetes are able to utilize a great variety of carbohydrates, like sugar. The particular kind of sugar and its concentration has decisive effect on the growth of microorganisms. The proper nutritional media aids also in the production of spores. Based on this generalization, that the growth and sporulation of microorganisms are greatly influenced by the nature and the concentration of carbohydrates, an attempt has been made to study Actinoplanes philippinensis with respect to this influence.

Advanced Molecular and Microbial Techniques: a Complete Laboratory Notebook

Advanced Molecular and Microbial Techniques: a Complete Laboratory Notebook

Date: May 1998
Creator: Brito-Rodriquez, Carmen Lydia
Description: The purpose of this project is to produce a complete and thorough notebook that may be used to supplement laboratory coursework. Its intent is to be used primarily by the students to aid them in understanding background information and the proper laboratory procedures involved in various types of experiments. The laboratory notebook is a summation of all the experiments and procedures used in the six-credit hour Advanced Microbial and Molecular Biology (BIOL 5160) course offered during the summer semester at the University of North Texas. This class is a team taught effort by Professors O'Donovan and Kunz. The course is constructed as an intensive practice exercise to teach the student about gene mutations, biosynthetic pathways, preparation and analysis of plasmid DNA, and many other topics included in the notebook.

The Age and Rate of Growth of the Black Crappie, Pomoxis Nigro-Maculatus (Le Sueur), and the White Crappie, Pomoxis Annularis Rafinesque, in the Koon Kreek Klub Lakes, Texas

The Age and Rate of Growth of the Black Crappie, Pomoxis Nigro-Maculatus (Le Sueur), and the White Crappie, Pomoxis Annularis Rafinesque, in the Koon Kreek Klub Lakes, Texas

Date: 1948
Creator: Elliott, James M.
Description: This study is another phase of the overall research program designed to furnish basic information for the management of East Texas lakes and has as its specific purpose the determination of the age and growth characteristics of two valuable species on these waters. The species to be considered are the black crappie, Pomoxis nigro-maculatus (Le Sueur) and the white crappie, Pomoxis annularis Rafinesque. Both species are highly regarded as food fish and have for many years offered recreational outlets for Texas fishermen.

Age, Growth, and Food Habits of the Largemouthed Black Bass (Micropterus Salmoides) and the Spotted Bass (Micropterus Puctulatus SSP) in North and East Texas Lakes

Age, Growth, and Food Habits of the Largemouthed Black Bass (Micropterus Salmoides) and the Spotted Bass (Micropterus Puctulatus SSP) in North and East Texas Lakes

Date: 1950
Creator: Cooper, William A.
Description: This study is based on the examinations and analyses of 388 largemouthed black bass (Micropterus salmoides) and 118 spotted black bass (Micropterus puctulatus ssp.) which were collected over a period of three years from 9 lakes in the North-Central and East Texas areas. The results should show the following: (1) the average age of the black bass in each of the nine reservoirs in Texas; (2) the growth rate of the bass in these reservoirs; (3) the feeding habits of the bass in all reservoirs studied; (4) a comparison of the growth rates of the largemouthed and spotted basses; and (5) a comparison of the growth rates of bass from Texas and Oklahoma.

Altered Leukemogenic Activity by Thyrotropic Treatment of Leukemic Mouse Thymus in Vitro

Altered Leukemogenic Activity by Thyrotropic Treatment of Leukemic Mouse Thymus in Vitro

Date: 1956
Creator: Rains, Robert Milton
Description: This investigation was planned to observe if the leukemic thymic tissue in vitro would inactivate TSH and to study the effect that TSH would have on the leukemogenic properties of these cells when transplanted into a high-leukemia strain of mice.

Analysis and expression of the cotton gene for the D-12 fatty acid desaturases 2-4 (FAD2-4)

Analysis and expression of the cotton gene for the D-12 fatty acid desaturases 2-4 (FAD2-4)

Date: August 2003
Creator: Park, Stacy J.
Description: A genomic clone containing a 16.9-kb segment of cotton DNA was found to encompass a D-12 fatty acid desaturases (FAD2-4) gene. The FAD2-4 gene has a single, large intron of 2,780 bp in its 5'-untranslated region, just 12 bp upstream from the ATG initiation codon of the FAD2-4 opening reading frame. A number of prospective promoter elements, including several light-responsive sequences, occur in the 5'-flanking region. The coding region of the gene is 1155 bp with no introns, and would encode a FAD2-4 polypeptide of 384 amino acids. The putative protein had four membrane-spanning helices, hallmarks of an integral membrane protein, and would probably be located in the endoplasmic reticulum. The FAD2-4 gene is indeed a functional gene, since yeast cells transformed with a plasmid containing the coding region of the gene synthesize an appreciable amount of linoleic acid (18:2), not normally made in wild-type yeast cells. The FAD2-4 gene has many structural similarities to the cotton FAD2-3 gene that was also analyzed in this laboratory.
