Diagnostic Implications Of Antigen-Induced Gamma Interferon, Nitric Oxide, And Tumor Necrosis Factor Alpha Production By Peripheral Blood Mononuclear Cells From Mycobacterium Bovis-Infected Cattle, W. R. Waters, M. V. Palmer, D. L. Whipple, M. P. Carlson, B. J. Nonnecke

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Bovine tuberculosis in the United States has proven costly to cattle producers as well as to government regulatory agencies. While in vivo responsiveness to mycobacterial antigens is the current standard for the diagnosis of tuberculosis, in vitro assays are gaining acceptance, especially as ancillary or complementary tests. To evaluate in vitro indices of cellular sensitization, antigen-induced gamma interferon (IFN-γ), nitric oxide (NO), and tumor necrosis factor alpha (TNF-α) responses by blood mononuclear cells from Mycobacterium bovis-infected cattle were quantified and compared. Using an aerosol model of infection, two doses of each of two strains of M. bovis (95-1315 and …

B.R. Wells Rice Research Studies 2002, R. J. Norman, J.-F. Meullenet

Arkansas Agricultural Experiment Station Research Series

Arkansas is the leading rice producing state in the U .S .. representing almost 46% of the total U .S. production and almost 47% of the total acres planted to rice . Rice cultural practices vary across the state and across the U.S. However, due to changing political, environmental, and economic times, the practices arc dynamic. This survey was initiated in 2002 to monitor how the changing times reflect the changes in the way Arkansas rice producers approach their livelihood. The survey was conducted by polling county Extension agents in each of the counties in Arkansas that produce rice. Questions …

In Vitro Regeneration And Genetic Transformation Of Sesbania Drummondii: A Medicinally And Environmentally Important Plant, Satish Cheepala

Masters Theses & Specialist Projects

This study describes rapid propagation of Sesbania drummondii using nodal explants isolated from seedlings and young plants. The nodal segments proliferated into multiple shoots on Murashige and Skoog (MS) medium supplemented with 22.2 /M benzyladenine. Murashige and Skoog medium containing 2.2 and 4.5 //M thidiazuron induced 5 - 6 healthier shoots per axillary node from 3-month-old plants. Nodal segments cultured on MS medium containing combinations of benzyladenine (8.8 and 11.1 /JM) and either indole-3-butyric acid (0.24 - 2.46 //M) or indole-3-acetic acid (0.28 - 2.85 //M) produced fewer shoots. Callus when subcultured on 2.2 /LihA thidiazuron containing medium resulted in …

Chlorine Inactivation Of Adenovirus Type 40 And Feline Calicivirus, Jeanette A. Thurston-Enriquez, Charles N. Haas, Joseph Jacangelo, Charles P. Gerba

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Ct values, the concentration of free chlorine multiplied by time of contact with virus, were determined for free-chlorine inactivation experiments carried out with chloroform-extracted (dispersed) and non-chloroformextracted (aggregated) feline calicivirus (FCV), adenovirus type 40 (AD40), and polio virus type 1 (PV-1). Experiments were carried out with high and low pH and temperature conditions. Ct values were calculated directly from bench-scale free-chlorine inactivation experiments and from application of the efficiency factor Hom model. For each experimental condition, Ct values were higher at pH 8 than at pH 6, higher at 5°C than at 15°C, and higher for dispersed AD40 (dAD40) than …

Divergent Selection For Seedling Tiller Number In Big Bluestem And Switchgrass, Alexander J. Smart, Kenneth P. Vogel, Lowell E. Moser, Walter W. Stroup

Department of Agronomy and Horticulture: Faculty Publications

Selection at the seedling stage in forage grass breeding would be extremely useful if seedling traits are highly heritable and correlated to desired agronomic traits. Objectives of this study were to determine the response to selection for high shoot weight and divergent selection or seedling tiller number in big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicum virgatum L.) seedlings and obtain estimates of realized heritability for these traits. Base populations were breeding populations of ‘Pawnee’ big bluestem and ‘Pathfinder’ switchgrass. Divergent selection for single or multiple (three or more) tiller(s) 6 to 8 wk after planting in a …

Establishment And Seedling Growth Of Big Bluestem And Switchgrass Populations Divergently Selected For Seedling Tiller Number, Alexander J. Smart, Lowell E. Moser, Kenneth P. Vogel

Department of Agronomy and Horticulture: Faculty Publications

Selection at the seedling stage in grass breeding would be extremely useful if seedling traits are correlated to desired agronomic traits. The objective of this study was to evaluate seedling morphological development, plant growth, and field establishment of big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicum virgatum L.) populations that were developed by divergent selection for seed- ling tiller number while selecting for high shoot weight. Six populations were evaluated: (i) ‘Pawnee’ big bluestem base, (ii) ‘Pathfinder’ switchgrass base, (iii) big bluestem multiple tiller, (iv) big bluestem single tiller, (v) switchgrass multiple tiller, and (vi) switchgrass single tiller. …

Bcl-2 Family Members Inhibit Oxidative Stress-Induced Programmed Cell Death In Saccharomyces Cerevisiae, Shao-Rong Chen, David Dunigan, Martin Dickman

Department of Plant Pathology: Faculty Publications

Selected antiapoptotic genes were expressed in baker’s yeast (Saccharomyces cerevisiae) to evaluate cytoprotective effects during oxidative stress. When exposed to treatments resulting in the generation of reactive oxygen species (ROS), including H₂O₂, menadione, or heat shock, wild-type yeast died and exhibited apoptotic-like characteristics, consistent with previous studies. Yeast strains were generated expressing nematode ced-9, human bcl-2, or chicken bcl-xl genes. These transformants tolerated a range of oxidative stresses, did not display features associated with apoptosis, and remained viable under conditions that were lethal to wildtype yeast. Yeast strains expressing a mutant antiapoptotic gene (bcl-2 …

Substoichiometric Shifting In The Plant Mitochondrial Genome Is Influenced By A Gene Homologous To Muts, Ricardo V. Abdelnoor, Ryan Yule, Annakaisa Elo, Alan C. Christensen, Gilbert Meyer-Gauen, Sally A. Mackenzie

Center for Plant Science Innovation: Faculty Publications

The plant mitochondrial genome is retained in a multipartite structure that arises by a process of repeat-mediated homologous recombination. Low-frequency ectopic recombination also occurs, often producing sequence chimeras, aberrant ORFs, and novel subgenomic DNA molecules. This genomic plasticity may distinguish the plant mitochondrion from mammalian and fungal types. In plants, relative copy number of recombination-derived subgenomic DNA molecules within mitochondria is controlled by nuclear genes, and a genomic shifting process can result in their differential copy number suppression to nearly undetectable levels. We have cloned a nuclear gene that regulates mitochondrial substoichiometric shifting in Arabidopsis. The CHM gene was …
