Expression Of The Tobacco Β- 1,3-Glucanase Gene, Pr-2d, Following Induction Of Sar With Peronospora Tabacina, Deanna L. Funnell, Christopher B. Lawrence, Jeffrey F. Pedersen, Christopher L. Schardl Dec 2004

Expression Of The Tobacco Β- 1,3-Glucanase Gene, Pr-2d, Following Induction Of Sar With Peronospora Tabacina, Deanna L. Funnell, Christopher B. Lawrence, Jeffrey F. Pedersen, Christopher L. Schardl

Papers in Plant Pathology

Systemic acquired resistance (SAR) is induced following inoculation of Peronospora tabacina sporangia into the stems of Nicotiana tabacum plants highly susceptible to the pathogen. Previous results have shown that accumulation of acidic P-1,3-glucanases (PR-2's) following induction of SAR by P. tabacina may contribute to resistance to P. tabacina. We showed that up-regulation of the PR-2 gene, PR-2d, following stem inoculation with P. tabacina, is associated with SAR. Studies using plants transformed with GUS constructs containing the full length promoter from PR-2d or promoter deletions, provided evidence that a previously characterized regulatory element that is involved in response to ...

Buffalograss Germplasm Resistance To Blissus Occiduus (Hemiptera: Lygaeidae), Osman Gulsen, Tiffany Heng-Moss, Robert C. Shearman, P. Stephen Baenziger, Donald J. Lee, Frederick P. Baxendale

Faculty Publications: Department of Entomology

Plant germplasm collections may offer genetic variability useful in identifying insect resistance. The goal of this project was to evaluate buffalograss genotypes [Buchloe dactyloides (Nutt.) Engelm.] for resistance to the chinch bug, Blissus occiduus Barber (Hemiptera: Lygaeidae), and to relate resistance to ploidy level, chinch bug number, and pubescence. Forty-eight buffalograss genotypes from diverse geographic locations were evaluated in replicated studies under greenhouse conditions. Of the genotypes studied, four were highly resistant, 22 were moderately resistant, 19 were moderately susceptible, and three were highly susceptible to chinch bug damage. The mean number of chinch bugs was significantly different among the ...

The 2002 Nebraska Nest Report, Wayne Mollhoff Dec 2004

The 2002 Nebraska Nest Report, Wayne Mollhoff

Nebraska Bird Review

In contrast to last year, with "the winter that wouldn't end," this breeding season began with a "spring that wouldn't begin." The winter was mild and uneventful, but although the spring was neither cold nor stormy, the usual warm-up did not come, and when the weather finally warmed in May, it brought no moisture. The resulting drought was worst in the west and southwest, areas that had already been abnormally dry for several years. In mid-June in the southern Panhandle, many ranchers were still feeding hay to the cattle because the grass simply did not grow. The dry ...


Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton Dec 2004

Lake Mcconaughy And Nebraska Piping Plover Recovery Goals, Mark M. Peyton

Nebraska Bird Review

Since 1992 the Central Nebraska Public Power and Irrigation District (Central) has protected and monitored nesting Piping Plovers along the shore of Lake McConaughy (Keith County, Nebraska). Over those 13 seasons, Central monitored 849 Piping Plover nests and documented the successful fledging (successful fledging is defined as a chick at least 24 days old, or one observed flying) of 1,237 Piping Plover chicks (Table 1), making Lake McConaughy one of the most productive nesting areas for Piping Plovers in Nebraska. The following is a documentation of the contributions of Lake McConaughy to the recovery goals for Piping Plovers in ...


Fall Field Report, August-November 2004, W. Ross Silcock Dec 2004

Fall Field Report, August-November 2004, W. Ross Silcock

Nebraska Bird Review

The fall season is a mix of summer, fall migration, and winter. Thus there are breeding records of interest, such as Mississippi Kites nesting at Red Cloud, only the 2nd known location in Nebraska, and only the 3rd documented breeding record for Northern Parula, despite its common summer residency. Fall migration generates early arrival dates, high counts, and late departure dates, the last seemingly more numerous as our average temperatures increase. Included in the late departure category were several late shorebirds, Great Egret and White-faced Ibis, and even the latest ever Black-throated Blue Warbler.

Counts of interest were 3000 Double-crested ...

Does Birding Have A Future?, Rick Wright Dec 2004

Does Birding Have A Future?, Rick Wright

Nebraska Bird Review

Does birding have a future?

Now this might seem an odd question, even an absurd question, to pose to an audience like this, and the answer might seem obvious. How could birding not have a future when we, all of us, are birders who bird, and when survey after recent survey assures us that our numbers are growing, our diversity increasing, and our economic and ethical contributions to American society ever more conspicuous. Does birding have a future? The simple answer is yes.

That's the simple answer. The more interesting answer is yes-yes, but. Yes, birding has a future ...

Abomasal Parasites In Wild Sympatric Cervids, Red Deer, Cervus Elaphus, And Fallow Deer, Dama Dama, From Three Localities Across Central And Western Spain: Relationship To Host Density And Park Management, Mónica Santín-Durán, José M. Alunda, Eric P. Hoberg, Concepción De La Fuente

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

A survey of abomasal parasites in cervids from Central Spain was conducted at three sites, Quintos de Mora (Toledo), Maluéñez de Arriba (Cáceres), and La Herguijuela (Cáceres). Commonly occurring helminths belonged to three polymorphic species of the Ostertagiinae: Spiculopteragia asymmetrica/S. quadrispiculata, Ostertagia leptospicularis/O. kolchida, and O. drozdzi/O. ryjikovi. Trichostrongylus axei was found in very few cases. Ostertagia drozdzi/O. ryjikovi and the minor male morphotype, S. quadrispiculata, are reported for the first time in red deer from Spain. The three ostertagiine species are also reported for the first time in fallow deer from Spain. These three species ...

Interferon Regulatory Factor 7 Is Associated With Epstein-Barr Virus-Transformed Central Nervous System Lymphoma And Has Oncogenic Properties, Luwen Zhang, Jun Zhang, Que Lambert, Channing J. Der, Luis Del Valle, Judith Miklossy, Kamel Kahlili, You Zhou, Joseph S. Pagano Dec 2004

Interferon Regulatory Factor 7 Is Associated With Epstein-Barr Virus-Transformed Central Nervous System Lymphoma And Has Oncogenic Properties, Luwen Zhang, Jun Zhang, Que Lambert, Channing J. Der, Luis Del Valle, Judith Miklossy, Kamel Kahlili, You Zhou, Joseph S. Pagano

Virology Papers

EBV transforms primary B cells, and the major EBV oncoprotein, latent membrane protein 1 (LMP-1), is required for the process. LMP-1 both induces the expression of IRF-7 and activates the IRF-7 protein by phosphorylation and nuclear translocation. Here we report that the expression of IRF-7 is increased in EBV-immortalized B lymphocytes compared with that in primary B cells. IRF-7 was phosphorylated and predominantly localized in the nucleus in the immortalized cells. The expression of IRF-7 was detected in 19 of 27 specimens of primary lymphomas of the human central nervous system by immunohistochemical analysis. The association between LMP-1 and IRF-7 ...


Agronomic Responses Of Corn Hybrids From Different Eras To Deficit And Adequate Levels Of Water And Nitrogen, Patrick M. O'Neill, J.F. Shanahan, James S. Schepers, Bob Caldwell Dec 2004

Agronomic Responses Of Corn Hybrids From Different Eras To Deficit And Adequate Levels Of Water And Nitrogen, Patrick M. O'Neill, J.F. Shanahan, James S. Schepers, Bob Caldwell

Agronomy & Horticulture -- Faculty Publications

Maintaining current high yields of corn (Zea mays L.) grown in the USA poses an environmental threat due to continued overuse of water and N inputs. To reduce overreliance on inputs, future corn breeding efforts should focus on improving tolerance of corn to water and N stresses, utilizing appropriate tolerance mechanisms. The objective of this study was to identify appropriate mechanisms by characterizing agronomic responses of 12 hybrids from three different eras (‘B73 x Mo17’ from 1970s and three early 1990s and eight late 1990s Pioneer brand hybrids) to varying water and N supply. This was done by growing the ...

Agronomy & Horticulture -- Faculty Publications

Military training can often be destructive to the environment. Environmental impacts associated with heavy training include soil compaction, soil erosion, siltation of waterways and wetlands, increased threat of flooding, loss of wildlife habitat, declining biodiversity, and invasion by noxious weeds. Planning and implementing land rehabilitation projects generally involves some soil movement, establishment of vegetation, stabilization and hardening of sites, etc. Procurement of appropriate heavy equipment and other specialized equipment is sometimes a difficult task that involves obtaining multiple vendors, especially when procuring equipment for rental, lease, or purchase. This report and associated database were created to help land managers easily ...

Agronomy & Horticulture -- Faculty Publications

Military training often results in environmental degradation that has negative impacts on future training missions. The U.S. Army Construction Engineering Research Laboratory (CERL) conceptualized the Army’s Integrated Training Area Management (ITAM) program in response to the concerns expressed by military land managers and trainers over the declining condition of training and testing lands. ITAM has evolved to include land condition and trend analysis (LCTA), environmental awareness (EA), training requirements integration (TRI), and land rehabilitation and maintenance (LRAM). The need for LRAM has increased dramatically over the past decade. Among the many difficulties faced in planning and implementing a ...

Follicular Development And Maturation In Gilts Selected For An Index Of High Ovulation Rate And High Prenatal Survival, H.-W. Yen, J. J. Ford, D. R. Zimmerman, R. K. Johnson

Faculty Papers and Publications in Animal Science

Seventy-one 10th-generation gilts from White Line-1 (WL-1 = randomly selected control line) and White Line-2 (WL-2 = selected for an index of ovulation rate and prenatal survival rate) were used to compare the pattern of follicular development and atresia during the follicular phase of the estrous cycle. Gilts were treated with PGF on d 13 of the estrous cycle (d 0 of induced follicular development) to induce luteolysis and assigned randomly within line and sire for ovary recovery on d 0, 2, 3, 4, 5, and the day after estrus. Ovaries were evaluated for numbers of corpora albicantia and small (2 ...


The Revised Classification For Scarabaeoidea: What The Hell Is Going On?, Brett C. Ratcliffe, Mary Liz Jameson Nov 2004

The Revised Classification For Scarabaeoidea: What The Hell Is Going On?, Brett C. Ratcliffe, Mary Liz Jameson

Papers in Entomology

Considering the turmoil and vast changes in the classification of the superfamily Scarabaeoidea during the last 20 years, particularly in North America, we were asked to provide an update for the readers of Scarabs wherein we offer our perspectives. Much of what follows is extracted from our scarabaeoid introduction in American Beetles (Jameson and Ratcliffe 2002). By the time this overview is printed, there may have been more changes in the classification because of the rapidly accumulating evidence supporting new hypotheses.

These rapid changes are a result of intensified study of the family groups using both traditional morphological evidence combined ...
