Effects Of Stratification, Warm Treatment, And Mechanical And Acid Scarification On The Emergence Of Yellow-Flowered Alfalfa (Medicago Sativa Subsp. Falcata) Seeds, Diane Narem Jan 2009

Effects Of Stratification, Warm Treatment, And Mechanical And Acid Scarification On The Emergence Of Yellow-Flowered Alfalfa (Medicago Sativa Subsp. Falcata) Seeds, Diane Narem

The Journal of Undergraduate Research

Yellow-flowered alfalfa (YFA) has great potential to improve rangelands in the Northern Plains. Greater than 99% of YFA seeds from soil were viable but less than 4% germinated under standard laboratory conditions. The objective was to determine if low germination was due to physical or physiological seed dormancy. The experiment utilized a random complete block design with two trials, eight replications per trial. Each replication consisted of ten treatments plus a control, four stratification treatments consisting of a combination of two temperatures (-5°C, -20°C) and two durations (48 hr, 72 hr), one warm treatment (4 min, 60°C), four sandpaper scarification …

Time And Temperature Requirements For Effective Removal Of High Molecular Weight Rna From Winter Wheat Genomic Dna With Licl, Benjamin Meyerink, Ryan Geraets

The Journal of Undergraduate Research

Numerous protocols are available for the isolation of plant genomic DNA. Often times, these protocols utilize a wide variety of solutions. The primary purpose of this project was to examine the use of LiCl for the removal of RNA contaminants within genomic DNA samples and its dependency on incubation time and temperature. Our results indicate that LiCl is sufficient for the removal of high molecular weight RNA contaminants from genomic DNA. In addition, our results illustrate varying incubation times with LiCl yield minimal differences in the recovery of genomic DNA and the removal of RNA contaminants. Alternatively, different incubation temperatures …

Biodiversity Maintenance Mechanisms Differ Between Native And Novel Exotic-Dominated Communities, Brian J. Wilsey, Terri B. Teaschner, Pedram P. Daneshgar, Forest I. Isbell, H. Wayne Polley

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

In many systems, native communities are being replaced by novel exotic-dominated ones. We experimentally compared species diversity decline between nine-species grassland communities under field conditions to test whether diversity maintenance mechanisms differed between communities containing all exotic or all native species using a pool of 40 species. Aboveground biomass was greater in exotic than native plots, and this difference was larger in mixtures than in monocultures. Species diversity declined more in exotic than native communities and declines were explained by different mechanisms. In exotic communities, overyielding species had high biomass in monoculture and diversity declined linearly as this selection effect …

Kelley, Andrew C. Procter, Dafeng Hui, Virgina L. Jin, Robert B. Jackson, Hyrum B. Johnson, H. Wayne Polley

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

Field studies of atmospheric CO2 effects on ecosystems usually include few levels of CO2 and a single soil type, making it difficult to ascertain the shape of responses to increasing CO2 or to generalize across soil types. The Lysimeter CO2 Gradient (LYCOG) chambers were constructed to maintain a linear gradient of atmospheric CO2 (~250 to 500 µ 1-1) on grassland vegetation established on intact soil monoliths from three soil series. The chambers maintained a linear daytime CO2 gradient from 263 µ 1-1 at the subambient end of the gradient to 502 …

Phylogenetic Classification Of Escherichia Coli O157:H7 Strains Of Human And Bovine Origin Using A Novel Set Of Nucleotide Polymorphisms, Michael L. Clawson, James Keen, Timothy Smith, Lisa Durso, Tara G. Mcdaneld, Robert Mandrell, Margaret Davis, James Bono

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

Background: Cattle are a reservoir of Shiga toxin-producing Escherichia coli O157:H7 (STEC O157), and are known to harbor subtypes not typically found in clinically ill humans. Consequently, nucleotide polymorphisms previously discovered via strains originating from human outbreaks may be restricted in their ability to distinguish STEC O157 genetic subtypes present in cattle. The objectives of this study were firstly to identify nucleotide polymorphisms in a diverse sampling of human and bovine STEC O157 strains, secondly to classify strains of either bovine or human origin by polymorphism-derived genotypes, and finally to compare the genotype diversity with pulsed-field gel electrophoresis (PFGE), a …

Sorption Of Phosphorus From Swine, Dairy, And Poultry Manures, Carl H. Bolster, Karamat R. Sistani Jan 2009

Sorption Of Phosphorus From Swine, Dairy, And Poultry Manures, Carl H. Bolster, Karamat R. Sistani

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

In most phosphorus (P) sorption studies, P is added as an inorganic salt to a predefined background solution such as calcium chloride (CaCl2) or potassium chloride (KCl); however, in many regions, the application of P to agricultural fields is in the form of animal manure. The purpose of this study, therefore, was to compare the sorption behavior of dissolved reactive P (DRP) in monopotassium phosphate (KH2PO4)–amended CaCl2 and KCl solutions with sorption behavior of DRP in three different animal manure extracts. Phosphorus single-point isotherms (PSI) were conducted on eight soils with the following …

Enzymatic Quantification Of Phytate In Animal Manure, Zhongqi He, Heidi W. Waldrip, C. Wayne Honeycutt, M. Susan Erich, Zachary N. Senwo

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

Phytate (inositol hexaphosphate) has been identified as a major organic phosphorus (P) form in soil, animal manure, and other environmental samples. Although a number of methods are available for quantitative isolation and determination of phytate, they are time-consuming and not amenable to routine analysis. We developed a simple, rapid method for enzymatic determination of phytate in animal manure. Animal manure was extracted by H2O, 1M hydrochloric acid (HCl), 0.1M sodium acetate (NaOAc, pH5.0) with or without 0.05M ethylenediaminetetraacetate (EDTA), and 0.25M or 0.5M sodium hydroxide (NaOH)–0.05M EDTA. Extracts were diluted (1/10–1/150) and adjusted to pH5.0 in sodium acetate …

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

Mineralization contributes significantly to agronomic nitrogen (N) budgets and is difficult to accurately predict. Models for predicting Nmineralization contributions are needed, and development of these models will require field-based data. In situ mineralization methods are intended to quantify N mineralization under ambient environmental conditions. This study was conducted to compare soil moisture and temperature in intact soil cores contained in cylinders to those in adjacent bulk soil, compare the effect of two resin-bag techniques on water content of soil within cylinders, and assess the effect of installation duration on inorganic N retention by resins. The study was conducted at a …

Natural Enemies Of The Coccinellidae: Parasites, Pathogens, And Parasitoids, E. W. Riddick, T. E. Cottrell, K. A. Kidd Jan 2009

Natural Enemies Of The Coccinellidae: Parasites, Pathogens, And Parasitoids, E. W. Riddick, T. E. Cottrell, K. A. Kidd

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

We review aspects of the life histories of representative enemies of coccinellids (both entomophagous and phytophagous species) and expose both potential and real effects that they have on life parameters of their hosts. Lady beetles are attacked by a variety of natural enemies (bacteria, fungi, mites, nematodes, protozoa, wasps, flies). Few of these enemies have the ability to alter significantly the population dynamics of their hosts. This review should encourage further research to help define the role of natural enemies in the population dynamics of coccinellids. Ultimately, the conservation of beneficial lady beetles and the management of nuisance and pestiferous …

Coccinellidae As Predators Of Mites: Stethorini In Biological Control, David J. Biddinger, Donald D. Weber, Larry A. Hull Jan 2009

Coccinellidae As Predators Of Mites: Stethorini In Biological Control, David J. Biddinger, Donald D. Weber, Larry A. Hull

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

The Stethorini are unique among the Coccinellidae in specializing on mites (principally Tetranychidae) as prey. Consisting of 90 species in two genera, Stethorus and Parasthethorus, the tribe is practically cosmopolitan. The Stethorini are found in a diverse range of habitats, including many agricultural systems such as pome and stone fruits, brambles, tree nuts, citrus, avocadoes, bananas, papaya, palms, tea, cassava, maize, strawberries, vegetables, and cotton, as well as ornamental plantings, grasslands, forests, and heathlands. Tetranychid mite outbreaks became common in many agricultural systems only after World War II, when widespread use of broad-spectrum insecticides increased. Stethorini were initially appreciated …

Visualization Of Biomass Solubilization And Cellulose Regeneration During Ionic Liquid Pretreatment Of Switchgrass, Seema Singh, Blake A. Simmons, Kenneth P. Vogel Jan 2009

Visualization Of Biomass Solubilization And Cellulose Regeneration During Ionic Liquid Pretreatment Of Switchgrass, Seema Singh, Blake A. Simmons, Kenneth P. Vogel

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

Auto-fluorescent mapping of plant cell walls was used to visualize cellulose and lignin in pristine switchgrass (Panicum virgatum) stems to determine the mechanisms of biomass dissolution during ionic liquid pretreatment. The addition of ground switchgrass to the ionic liquid 1-n-ethyl-3-methylimidazolium acetate resulted in the disruption and solubilization of the plant cell wall at mild temperatures. Swelling of the plant cell wall, attributed to disruption of inter- and intramolecular hydrogen bonding between cellulose fibrils and lignin, followed by complete dissolution of biomass, was observed without using imaging techniques that require staining, embedding, and processing of biomass. Subsequent …

7tmrmine: A Web Server For Hierarchical Mining Of 7tmr Proteins, Guoqing Lu, Zhifang Wang, Alan M. Jones, Etsuko N. Moriyama

Biology Faculty Publications

Background: Seven-transmembrane region-containing receptors (7TMRs) play central roles in eukaryotic signal transduction. Due to their biomedical importance, thorough mining of 7TMRs from diverse genomes has been an active target of bioinformatics and pharmacogenomics research. The need for new and accurate 7TMR/GPCR prediction tools is paramount with the accelerated rate of acquisition of diverse sequence information. Currently available and often used protein classification methods (e.g., profile hidden Markov Models) are highly accurate for identifying their membership information among already known 7TMR subfamilies. However, these alignment-based methods are less effective for identifying remote similarities, e.g., identifying proteins from highly divergent or possibly …

Limits To Maize Productivity In The Western Corn-Belt: A Simulation Analysis For Fully Irrigated And Rainfed Conditions, Patricio Grassini, Haishun Yang, Kenneth G. Cassman

Department of Agronomy and Horticulture: Faculty Publications

Unlike the Central and Eastern U.S. Corn-Belt where maize is grown almost entirely under rainfed conditions, maize in the Western Corn-Belt is produced under both irrigated (3.2 million ha) and rainfed (4.1 million ha) conditions. Simulation modeling, regression, and boundary-function analysis were used to assess constraints to maize productivity in the Western Corn-Belt. Aboveground biomass, grain yield, and water balance were simulated for fully irrigated and rainfed crops, using 20-year weather records from 18 locations in combination with actual soil, planting date, plant population, and hybrid-maturity data. Mean values of meteorological variables were estimated for three growth periods (pre- and …
