Accuracy Of Equations Predicting The Phyllochron Of Wheat, Gregory S. Mcmaster, Wallace Wilhelm
Accuracy Of Equations Predicting The Phyllochron Of Wheat, Gregory S. Mcmaster, Wallace Wilhelm
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Predicting the rate of leaf appearance, or phyllochron, aids in understanding and modeling grass development and growth. Nine equations predicting the phyllochron of wheat (Triticum aestivum L.) were evaluated using field data from a variety of locations, cultivars, and management practices. Each equation is referred to by the last name of the first author; if there is more than one equation by the first author, additional descriptors were included. The BAKER and KIRBY equations predict the phyllochron based on changes in daylength following seedling emergence; CAO-TEMP and CAO-DAY use a curvilinear relationship with temperature and daylength, respectively; CAO-T&D uses the …

United States Patent, Number: 5,466,788: Subgenomic Promoter, Paul G. Ahlquist, Roy C. French
Department of Plant Pathology: Faculty Publications
A subgenomic promoter of a positive strand RNA virus is disclosed which directs the amplified expression of a structural gene in plant tissue. The core region and an upstream activating domain of the subgenomic promoter are identified. This promoter can be utilized in a modified virus, or in an appropriate engineered recombinant DNA derivative, which may be chromosomally integrated or maintained as an episome in transformed cells.

Department of Agronomy and Horticulture: Faculty Publications
Four bell pepper (Capsicum annuum L.) cultivars were evaluated for yield (total weight of marketable fruit) performance over 41 environments as combinations of 3 years, three planting dates, and seven locations across North Carolina, South Carolina, and Georgia. Cultural practices, including trickle irrigation and double rows planted on black plastic-covered beds, were uniform across all environments, except for fertilization, which was adjusted at each location based on soil tests. Comparing production over 3 years between the mountain location and the Coastal Plain location in North Carolina, yields were lower on the Coastal Plain. Spring plantings provided higher yields than …

Plans For Crash-Tested Bridge Railings For Longitudinal Wood Decks, Michael A. Ritter, Ronald K. Faller, Paula D. Hilbrich Lee, Barry Thomas Rosson, Sheila Rimal Duwadi
USDA Forest Service / UNL Faculty Publications
In the past decade, bridge railing design criteria have moved away from static-load design and have focused on full-scale crash testing as a more appropriate and reliable means of evaluating bridge railings. The five bridge railing plans presented reflect the results of a cooperative research project between the Midwest Roadside Safety Facility, University of Nebraska-Lincoln; the USDA Forest Service, Forest Products Laboraotry; and the Federal Highway Administration. The project objective was to develop and crash test bridge railings and approach railing transitions for longitudinal wood bridge decks. The bridge railings were completed in accordance with AASHTO Performance Levell, Performance Level …

Weed Suppression With Grazing Or Atrazine During Big Bluestem Establishment, B. Keith Lawrence, Steven S. Waller, Lowell E. Moser, Bruce Anderson, Larry L. Larson
Weed Suppression With Grazing Or Atrazine During Big Bluestem Establishment, B. Keith Lawrence, Steven S. Waller, Lowell E. Moser, Bruce Anderson, Larry L. Larson
Department of Agronomy and Horticulture: Faculty Publications
Weed competition is a major factor causing warm-season grass seeding failures in rangeland and cropland. With a limited number of herbicides available for weed control, grazing may reduce competing vegetation in seedings and serve as an alternative to herbicides. Many immature needy forbs and grasses are palatable to cattle and contain high nutrient levels. Research was conducted (RCBD, 4 reps) comparing grazing by yearling cattle with chemical suppression [atrazine (6-chloro-N-ethyl-N’- (methylethyl)-1, 3, 5-triazine-2, 4-diamine)] for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedlings at Mead, Nebr. on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic …
Inhibition Of Chloroplast Dna Recombination And Repair By Dominant Negative Mutants Of Escherichia Coli Reca, Heriberto D. Cerutti, Anita M. Johnson, John E. Boynton, Nicholas W. Gillham
Inhibition Of Chloroplast Dna Recombination And Repair By Dominant Negative Mutants Of Escherichia Coli Reca, Heriberto D. Cerutti, Anita M. Johnson, John E. Boynton, Nicholas W. Gillham
Center for Plant Science Innovation: Faculty and Staff Publications
Escherichia coli RecA, suggest that the plastid recombination system is related to its eubacterial counterpart. Therefore, we examined whether dominant negative mutants of the E. coli RecA protein can interfere with the activity of their putative homolog in the chloroplast of the unicellular green alga Chlamydomonas reinhardtii. Transformants expressing these mutant RecA proteins showed reduced survival rates when exposed to DNA-damaging agents, deficient repair of chloroplast DNA, and diminished plastid DNA recombination. These results strongly support the existence of a RecA-mediated recombination system in chloroplasts. We also found that the wild-type E. coli RecA protein enhances the frequency of …

Research On Plant Disease And Pest Management Is Essential To Sustainable Agriculture, R. James Cook, Clifford J. Gabriel, Arthur Kelman, S. Tolin, Anne K. Vidaver
Research On Plant Disease And Pest Management Is Essential To Sustainable Agriculture, R. James Cook, Clifford J. Gabriel, Arthur Kelman, S. Tolin, Anne K. Vidaver
Department of Plant Pathology: Faculty Publications
In the United States, a country with food in great abundance, it is difficult to realize that, were it not for the current level of plant disease and pest management, most human resources would be needed to obtain enough food and other plant and animal products merely to survive. Instead, there are surpluses, markets for many agricultural products are depressed, and funds available for research on plant disease and pest management-and for agricultural research generally-have plateaud or are declining.
Why does the United States need more research on plant disease and pest management? Because the health and productivity of the …

Movement Of Dna Across The Chloroplast Envelope: Implications For The Transfer Of Promiscuous Dna, Heriberto D. Cerutti, André Jagendorf
Movement Of Dna Across The Chloroplast Envelope: Implications For The Transfer Of Promiscuous Dna, Heriberto D. Cerutti, André Jagendorf
Center for Plant Science Innovation: Faculty and Staff Publications
Little is known about the mechanistic basis for the movement of promiscuous nucleic acids across cell membranes. To address this problem we sought conditions that would permit the entry of plasmid DNA into isolated, intact pea chloroplasts. DNA uptake did not occur normally, but was induced by hypotonic treatments, by incubation with millimolar levels of Mg2+, or by heat shock at 42 °C. These results are consistent with DNA movement being permitted by conditions that transiently alter the permeability of the chloroplast envelope. Plant cells are subject to osmotic tensions and/or conditions inducing polymorphic changes in the membranes, …

Corn-Soybean Rotation Effects On Soil And Plant N Indices, G. E. Varvel, N. L. Klocke, Wallace Wilhelm
Corn-Soybean Rotation Effects On Soil And Plant N Indices, G. E. Varvel, N. L. Klocke, Wallace Wilhelm
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
An irrigated study comparing monoculture corn and corn-soybean systems is being conducted on a uniform site in the Platte Valley of Nebraska. Four corn hybrids differing in yield potential, maturity, and stay-green characteristics are used in both the monoculture and rotation systems with five N-fertilizer rates. Stalk nitrate-nitrogen concentrations determined in mature corn plants at harvest have been used in many areas of the country as an indicator of the amount of N available to those plants. In this study, stalk nitrate-nitrogen concentrations (taken after the 1992 and 1993 growing seasons) reflected differences in N status between and within the …
Reproductive Structure And Organogenesis In A Cottonwood, Populus Deltoides (Salicaceae), Robert B. Kaul
Reproductive Structure And Organogenesis In A Cottonwood, Populus Deltoides (Salicaceae), Robert B. Kaul
School of Biological Sciences: Faculty Publications
The organogenesis of inflorescences, flowers, and fruits was followed for two years in a male and a female tree of eastern cottonwood, Populus deltoides. Soon after anthesis, an inflorescence for the next year is initiated as a continuation of the apical meristem in most axillary buds of the extension shoot of the current year. Bract and then floral primordia arise helically, and by the end of summer all floral appendages are evident. Individual perianth parts are evident early in ontogeny but not at anthesis; they are vascularized independently by distal traces of discrete vascular strands that also serve the …
Yield And N Uptake Of Inbred Corn With Reduced N-Fertilizer Application, Wallace Wilhelm, B. E. Johnson, R. Koopman, W. R. Peterson
Yield And N Uptake Of Inbred Corn With Reduced N-Fertilizer Application, Wallace Wilhelm, B. E. Johnson, R. Koopman, W. R. Peterson
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Most corn planted in the United States is a single-cross hybrid; therefore the seed is produced on inbred lines. Inbreds are known to be less productive than the resultant hybrids; however, growers and seed companies want to maximize seed production. To this end growers attempt to keep mineral nutrition, especially nitrogen, non-limiting. Low production potential and high N fertilization rates can result in the likelihood of groundwater contamination. Key to proper N application is knowledge of the N response of inbred lines. The purpose of this research was to determine the yield and N uptake response of a group of …

Addition Of Cellulolytic Clostridia To The Bovine Rumen And Pig Intestinal Tract, Vincent H. Varel, J.T. Yen, Kelly K. Kreikmeier
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Studies were conducted to determine whether intestinal cellulolytic bacteria could be introduced into the bovine rumen or pig large intestine. In the first study, the ruminal fluid of three cows was evacuated and replaced with 20 liters of buffer and 6 liters of the ruminal or swine cellulolytic organism Clostridium longisporum or Clostridium herbivorans, respectively. The introduced organisms were the predominant cellulolytic bacterium in the fluid (>107 cells ml21) at 0 h. C. longisporum was still the predominant cellulolytic organism after 5 h, at 0.55 3 107 cells ml21; however, after 24 h the count of C. longisporum …
