The Commons Concept And Intellectual Property Rights Regime: Whither Plant Genetic Resources And Traditional Knowledge?, Chika B. Onwuekwe

The University of New Hampshire Law Review

[Excerpt] "The classification of plant genetic resources (PGRs) as the common heritage of humankind continues to generate controversies. The debate is between developing countries that are the primary sources of these resources and industrialized, biotechnologically advanced countries that appropriate and utilize PGRs as raw materials for various commercial products, such as medicine, seed variety, or pesticides. Scholars of diverse backgrounds express various opinions on whether PGRs obtained from plants found within a territory of a sovereign state should properly be designated “common heritage of humankind” or regarded as part of the “commons,” and therefore freely accessible. The debate also extends …

Moisture--Temperature Management During Alfalfa Hay And Silage Making & Storing, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

In some areas of the country, producers store a substantial portion of their forage for winter feeding as silage or haylage. However, hay remains the most popular storage method for forage. Hay stores well for long periods and is better suited to cash sale and transportation than silage. Mechanical conditioning, which gained acceptance during the 1950's is probably still the greatest single change in hay harvesting and storage technology during this century. However, a number of other noteworthy changes and innovations have occurred in recent years which have helped to reduce the extent of losses during hay harvesting and storage.

Complete Nucleotide Sequence Of Oat Necrotic Mottle Virus: A Distinct Tritimovirus Species (Family Potyviridae) Most, D.C. Stenger, Roy C. French

Department of Plant Pathology: Faculty Publications

The RNA genome (9346 nucleotides) of Oat necrotic mottle virus (ONMV) was cloned and sequenced. Complete genome comparisons indicated that ONMV, currently classified as a rymovirus, was most closely related (~73% nucleotide, ~79% amino acid identity) to the tritimovirus Wheat streak mosaic virus (WSMV). ONMV encoded a single polyprotein, with proteinase cleavage sites very similar to those ofWSMV. Pairwise comparison of ONMV andWSMV cistrons revealed that P3 was most conserved (~79% nucleotide, ~86% amino acid), whereas HC-Pro was most divergent (~67% nucleotide, ~69% amino acid). In contrast, the ONMV sequence was distantly related (~40% nt, ~26% amino acid identity) to …

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 …

Establishing Effects Of Application Of Swine Manure On Crop Leaf Damage To Growing Crops, Charles Shapiro, University Of Nebraska-Lincoln

Department of Agronomy and Horticulture: Faculty Publications

Swine manure from a below barn storage facility was applied to growing corn and soybeans to determine phytotoxic effects. The manure had an electrical conductivity of around 20 mmhos/cm and was diluted for treatment at full, half, quarter and none. The manure mixtures were applied at a rate of 0.5 in/acre using a procedure that wet the foliage three times in a 15-minute time span. Manure mixtures were applied at V7 and V14 for corn and V3 and R1 for soybeans. Phytotoxic effects were shown at the high rate for both crops, but soybeans were killed at the early application …

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”.

Phenotypic And Genotypic Characterization Of Uromyces Appendiculatus From Phaseolus Vulgaris In The Americas, C. M. Araya, A. T. Alleyne, J. R. Steadman, Kent M. Eskridge, D. P. Coyne

Department of Plant Pathology: Faculty Publications

Populations of 90 Uromyces appendiculatus isolates were collected from throughout the Americas and evaluated for virulence on 19 standard bean rust differentials, and also on 12 landraces of Phaseolus vulgaris from South and Central America. The landrace differentials represented geographical centers of bean domestication. Three groups were observed. Two groups were isolates from centers of bean domestication and a third heterogeneous group comprised isolates from countries in South and Central America. Molecular analysis using random amplified polymorphic DNA–polymerase chain reaction (RAPD-PCR) was also conducted on these isolates. Cluster analysis of the molecular profiles showed three groups that corresponded to those …

Topcrop W.A. State Focus 2002-2003 Wheat Protein, Alison Slade, Jeremy Lemon

Bulletins 4000 -

The State Focus program is supported by the Grains Research and Development Corporation (GRDC) in conjunction with TOPCROP to provide grower groups with a new learning concept. The concept was developed in Victoria and has been adopted by South Australia and Western Australia.

Wheat protein was selected as the Western Australian State Focus in response to a wide-ranging consultation of grower groups, researchers and the TOPCROP West management group. As crop yield potential increases through matching varieties to growing season length, weed and disease control, and timely sowing systems, the crop’s demand for nitrogen increases. Unless the demand is matched …

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 …

An Analysis Of Vegetation And Environmental Parameters At Mitigated Wetland Sites Located In The Upper Scioto River Drainage Basin, Central Ohio, Desiree L. Lawson

Theses, Dissertations and Capstones

The construction of wetland mitigation sites to compensate for authorized losses is necessary under Section 404 of the Clean Water Act. Many mitigation sites have been determined to be unsuccessful. Monitoring of sites is necessary to determine if functions of natural wetlands have been replaced. Six mitigation sites in the Upper Scioto River watershed in central Ohio were chosen for study. Representative transects were established beginning in uplands adjacent to the wetlands (old field, OF), running through areas characterized by seasonal inundation (seasonally pooled, SP) and ending in permanent pools of inundation characterized by little or no vegetation (permanent pooled …

Grass Or Trees? Performance Of Riparian Buffers Under Natural Rainfall Conditions, Australia, Lucy Mckergow, I Prosser, R Grayson, David Weaver, D Heiner

Journal articles

Riparian vegetation can trap sediment and nutrients derived from hillslopes. Most research into the effectiveness of riparian buffers has been experimental and little quantitative data exists on performance under natural field conditions. This study reports on grass and tree buffer performance under natural rainfall conditions in two contrasting Australian environments. Buffers receiving runoff from hillslopes cropped with bananas were monitored over a 4-year period in the wet topics of Far North Queensland (FNQ). Runoff, bedload and suspended loads were measured leaving the crop and leaving 15 m wide dense grass and remnant rainforest riparian buffers. The grass buffer was able …

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 …
