Biotechnology And The Law: A Consideration Of Intellectual Property Rights And Related Social Issues, Michael D. Mehta

The University of New Hampshire Law Review

[Excerpt] “Recent advances in biotechnology are expected by many to improve crop yield, reduce reliance on agricultural inputs like pesticides and herbicides, alleviate world hunger, improve the safety and effectiveness of pharmaceuticals, assist in the discovery of genes that trigger diseases like cancer, and make more efficient our legal institutions through DNA testing. Clearly, innovations in biotechnology are a powerful force for social change, and they pose unique challenges and opportunities for legal scholars and institutions. This section of the Pierce Law Review focuses on the interface between law and technology by examining how innovations in biotechnology accelerate debates about …

Balancing Agronomics And Economics Of Alfalfa Hay Production, Brian Lacefield, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has high-yielding, high-quality, persistent, and profitable potential if given adequate management and a balance of several agronomic and economic considerations. How can we account for the differences among producers who have the average alfalfa yields of 3.0 tons/A with the top hay producers who average approximately 5.0 tons/acre and the producer who has achieved the record yield of 10.13 tons/acre? Is the answer “luck”, better soils, moisture and growing conditions? The answer may certainly be yes, but. Yes, the factors above are important and can explain some differences; however, we believe the overall difference is the management of research-based …

Grazing Alfalfa, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Over the past decade we have had several people address “Alfalfa as a Grazing Crop” including Warren Thompson, Gary Bates, Ken Johnson, Jason Sandefur, Byron Sleugh, and myself. Each has done an excellent job discussing the merits of this remarkable crop and the opportunities it offers for grazing. At the end of the Conference last year, I (as I always do) asked for your suggestions concerning topics for this years’ conference. As it has been for the past decade, “Grazing” was the most requested topic. In today’s presentation, let’s go back and revisit the question, “Is Grazing Alfalfa Right for …

Gene Expression Profiling Of Bovine Macrophages In Response To Escherichia Coli O157:H7 Lipopolysaccharide, Carol G. Chitko-Mckown, James M. Fox, Laura C. Miller, Michael P. Heaton, James L. Bono, James E. Keen, William M. Grosse, William W. Laegried

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

The aim of this study was to identify changes in bovine macrophage gene expression in response to treatment with Escherichia coli 0157:H7 lipopolysaccharide (LPS), utilizing a human gene microarray. Bovine cDNA from control and LPStreated primary macrophages hybridized to greater than 5644 (79.8%) of the non-control gene targets on a commercially available microarray containing greater than 7075 targets (Incyte Genomics, St. Louis, MO). Of these target sequences, 44 were differentially expressed upon exposure to LPS, including 18 genes not previously reported to exist in cattle. These included a pentaxin-related gene, CASP8, TNF-induced genes, interferon-induced genes, and inhibitors of apoptosis. Using …

Appropriateness Of Management Zones For Characterizing Spatial Variability Of Soil Properties And Irrigated Corn Yields Across Years, Aaron R. Schepers, J.F. Shanahan, Mark A. Liebig, James S. Schepers, Sven Johnson, Ariovaldo Luchiari Jr.

Department of Agronomy and Horticulture: Faculty Publications

Recent precision-agriculture research has focused on use of management zones (MZ) as a method for variable application of inputs like N. The objectives of this study were to determine (i) if landscape attributes could be aggregated into MZthat characterize spatial varia- tion in soil chemical properties and corn yields and (ii) if temporal variability affects expression of yield spatial variability. This work was conducted on an irrigated cornfield near Gibbon, NE. Five landscape attributes, including a soil brightness image (red, green, and blue bands), elevation, and apparent electrical conductivity, were acquired for the field.Ageoreferenced soil-sampling scheme was used to determine …

Prediction Of Leaf/Stem Ratio Using Near-Infrared Reflectance Spectroscopy (Nirs): A Technical Note, Alexander J. Smart, Walter H. Schacht, Lowell E. Moser, Jerry D. Volesky

Department of Agronomy and Horticulture: Faculty Publications

Leaf/stem ratio of grass stands is an important factor affecting diet selection, quality, and forage intake. Determination of leaf/stem ratio involves a labor-intensive process of hand separating leaf and stem fractions. Our objectives in this study were to evaluate leaf/stem ratio prediction using near-infrared reflectance spectroscopy (NIRS) in monocultures of big bluestem (Andropogon gerardii Vitman), switch- grass (Panicum virgatum L.), intermediate wheatgrass [Thinopyrum intermedian (Host) Barkw. & D.R. Dewey], and smooth bromegrass (Bromus inermis Leyss.). Samples of each species were hand-clipped from monocultures at four locations throughout Nebraska in the 1997 and 1998 growing seasons. Ground …

Forage & Grazing Lands: Morphological Characteristics Of Big Bluestem And Switchgrass Plants 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 useful if seedling traits were correlated to desired agronomic traits of mature plants. Objectives of this study were to determine if seedlings from big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicumvirgatum L.) populations that differ genetically in seedling tiller num- ber differ in mature plant (i) morphological characteristics, (ii) forage yield managed by a three-cut harvest system or a single end-of-season harvest, and (iii) leaf elongation rate. Field experiments were conducted on a Kennebec silt loam soil (fine-silty, mixed, superactive, mesic Cumulic Hapludolls). In addition, greenhouse studies were …

Closterovirus Bipolar Virion: Evidence For Initiation Of Assembly By Minor Coat Protein And Its Restriction To The Genomic Rna 5' Region, Satyanarayana Tatineni, Siddarame Gowda, Maria A. Ayllon, William O. Dawson

Department of Plant Pathology: Faculty Publications

The long flexuous virions of the Closteroviridae have a unique bipolar architecture incorporating two coat proteins, with most of the helical nucleocapsid encapsidated by the major coat protein (CP) and a small portion of one end encapsidated by the minor coat protein (CPm). It is not known whether CPm encapsidates the genomic RNA and, if so, which end and what effects transition between the two coat proteins. Two other virus-encoded proteins, an HSP70 homolog (HSP70h) and an = 61-kDa protein, are required to augment virion assembly. In this work, we examine the in vivo encapsidation of Citrus tristeza virus by …

Estimation Of Carbon Sequestration By Combining Remote Sensing And Net Ecosystem Exchange Data For Northern Mixed-Grass Prairie And Sagebrush–Steppe Ecosystems, E. Raymond Hunt Jr., Robert D. Kelly, William K. Smith, Jace T. Fahnestock, Jeffrey M. Welker, William A. Reiners

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

Carbon sequestration was estimated a northern mixed-grass prairie site and a sagebrush–steppe site in southeastern Wyoming using an approach that integrates remote sensing, CO₂ flux measurements, and meteorological data. Net ecosystem exchange (NEE) of CO₂ was measured using aircraft and ground flux techniques and was linearly related to absorbed photosynthetically active radiation (APAR). The slope of this relationship is the radiation use efficiency (ε = 0.51 g C/MJ APAR); there were no significant differences in the regression coefficients between the two sites. Furthermore, ecosystem chamber measurements of total respiration in 1998 and 1999 were used to develop …

Seven Basic Elements For A Successful Native Warm Season Grass Establishment For Forage Production, Randy Seymour, John Seymour

Forage Symposium at the Kentucky Cattlemen’s Convention

First, let’s make it clear from the start, there is NO justification for plowing up all of your cool season forages and replacing them with warm season forages.

We strongly believe, and can support our belief with practical evidence, that warm season native grasses, produced in DESIGNED AMOUNTS to complement cool season forages, will make money for the beef and dairy producer.

Managing Broomsedge In Pastures, Monroe Rasnake

Forage Symposium at the Kentucky Cattlemen’s Convention

Broomsedge, broomgrass, sagegrass (Andropogon Virginiana) is a perennial, warm season grass native to Kentucky. It is well adapted to the soils and climate of this area. Add to this the fact that it is relatively unpalatable to livestock and it is easy to understand why it is common in Kentucky pasture fields. The question then becomes: why is it a problem in some fields and not in others?

Getting More From Forages, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

In human endeavors, results are usually highly correlated with investments in terms of thought, time, effort, and a certain amount of money. In particular, the best and most profitable forage programs have had the most thought put into them. Top producers strive to continue to improve their operations by developing strategies, practices, and procedures that will result in “GETTING MORE FROM FORAGES”.

Age And Sex-Specific Rates Of Leaf Regeneration In The Mojave Desert Moss Syntrichia Caninervis, Lloyd Stark, L. Nichols, Nicholas N. Mcletchie, S. D. Smith, C. Zundel

Life Sciences Faculty Research

The extremely skewed female-biased sex ratio in the desert moss Syntrichia caninervis was investigated by assessing the regeneration capacity of detached leaves. Juvenile, green, yellow-green, and brown leaves equating to approximately 0, 2, 6, and 12 yr of age, respectively, were detached from individuals of S. caninervis collected from 10 field populations and grown in a growth chamber for 58 d at a light intensity of 33–128 µmol · m–2 · s–1. Younger leaves (0–2 yr old) tended to have a greater viability, regenerate more quickly, extend their protonemal filaments farther, produce shoots (gametophores) more quickly, produce more shoots, and …

Pseudomonas Syringae Type Iii Secretion System Targeting Signals And Novel Effectors Studied With A Cya Translocation Reporter, Lisa M. Schechter, Kathy A. Roberts, Yashitola Jamir, James R. Alfano, Alan Collmer

Center for Plant Science Innovation: Faculty Publications

Pseudomonas syringae pv. tomato strain DC3000 is a pathogen of tomato and Arabidopsis. The hrp-hrcencoded type III secretion system (TTSS), which injects bacterial effector proteins (primarily called Hop or Avr proteins) into plant cells, is required for pathogenicity. In addition to being regulated by the HrpL alternative sigma factor, most avr or hop genes encode proteins with N termini that have several characteristic features, including (i) a high percentage of Ser residues, (ii) an aliphatic amino acid (Ile, Leu, or Val) or Pro at the third or fourth position, and (iii) a lack of negatively charged …

Folate Synthesis In Plants: The P-Aminobenzoate Branch Is Initiated By A Bifunctional Paba–Pabb Protein That Is Targeted To Plastids, Gilles J. C. Basset, Eoin P. Quinlivan, Stéphane Ravanel, Fabrice Rébeillé, Brian P. Nichols, Kazuo Shinozaki, Motoaki Seki, Lori C. Adams-Phillips, James J. Giovannoni, Jesse F. Gregory Iii, Andrew D. Hanson

Center for Plant Science Innovation: Faculty Publications

It is not known how plants synthesize the p-aminobenzoate (PABA) moiety of folates. In Escherichia coli, PABA is made from chorismate in two steps. First, the PabA and PabB proteins interact to catalyze transfer of the amide nitrogen of glutamine to chorismate, forming 4-amino-4-deoxychorismate (ADC). The PabC protein then mediates elimination of pyruvate and aromatization to give PABA. Fungi, actinomycetes, and Plasmodium spp. also synthesize PABA but have proteins comprising fused domains homologous to PabA and PabB. These bipartite proteins are commonly called ‘‘PABA synthases,’’ although it is unclear whether they produce PABA or ADC. Genomic approaches identified …
