Responsive In-Season Nitrogen Management For Cereals, J.F. Shanahan, N. R. Kitchen, W. R. Raun, James S. Schepers

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

Current nitrogen (N) management strategies for worldwide cereal production systems are characterized by low N use efficiency (NUE), environmental contamination, and considerable ongoing debate regarding what can be done to improve N fertilizer management. Development of innovative strategies that improve NUE and minimize off-field losses is crucial to sustaining cereal-based farming. In this paper, we review the major managerial causes for low NUE, including (1) poor synchrony between fertilizer N and crop demand, (2) uniform field applications to spatially variable landscapes that commonly vary in crop N need, and (3) failure to account for temporally variable influences on crop N …

Expression And Evolutionary Relationships Of The Chenopodium Quinoa 11s Seed Storage Protein Gene, Mikel Stevens, Peter J. Maughan, Daniel J. Fairbanks, Marie R. B. Balzotti, Jennifer N. Thornton, David A. Mcclellan, Eric N. Jellen, Craig E. Coleman

Faculty Publications

Quinoa (Chenopodium quinoa Willd.) is a food crop cultivated by subsistence farmers and commercial growers on the high Andean plateau, primarily in Bolivia, Peru, and Chile. Present interest in quinoa is due to its tolerance of harsh environments and its nutritional value. It is thought that the seed storage proteins of quinoa, particularly the 11S globulins and 2S albumins, are responsible for the relatively high protein content and ideal amino acid balance of the quinoa seed. Here we report the genomic and cDNA sequences for two 11S genes representing two orthologous loci from the quinoa genome. Important features of the …

Uses Of The Pseudomonas Syringae Effector Protein Hopu1 Related To Itsability To Adp-Rbosylate Eukaryotc Rna Binding Protens, James R. Alfano, Zheng Qing Fu, Thomas E. Elthon

Department of Plant Pathology: Faculty Publications

The bacterial plant pathogen Pseudomonas Syringae injects effector proteins into host cells via a type III protein secre tion system to cause disease. The invention relates to the discovery that the type III effector HopU1 is a mono-ADP ribosyltransferase (ADP-RT) and suppresses plant innate immunity. The HopU1 substrates in Arabidopsis thaliana extracts were RNA-binding proteins that possess RNA recognition motifs (RRMs). A. thaliana knock-out lines defective in the glycine-rich RNA-binding protein AtGRP7, a HopU1 substrate, were more susceptible than wild type plants to P syringae. The ADP-ribosylation of AtGRP7 by HopU1 required two arginines within the RRM. The inven tion …

Decomposition Of Bt And Non-Bt Corn Hybrid Residues In The Field, David D. Tarkalson, Stephen D. Kachman, Johannes M. H. Knops, Janice E. Thies, Charles S. Wortmann

Department of Agronomy and Horticulture: Faculty Publications

Results of a previous laboratory study indicated that six transgenic crops expressing the Cry1Ab insecticidal protein from Bacillus thuringiensis (Bt) decomposed at a slower rate than their respective non-Bt isolines. Consequently, litter decomposition rates, nitrogen cycling, and carbon pools may change in agricultural systems as the result of the widespread use of Bt crops. In this study, we assessed the decomposition rates and chemical composition of commonly grown hybrids of Bt and non-Bt isolines of corn (Zea mays L.) in the field. Leaves, stalks, and cobs from two Bt corn hybrids (Pioneer 34N44 Bt and NC+ 4990 Bt) and their …

The Expression Of Microrna Mir-107 Decreases Early In Alzheimer's Disease And May Accelerate Disease Progression Through Regulation Of Β-Site Amyloid Precursor Protein-Cleaving Enzyme 1, Wang-Xia Wang, Bernard W. Rajeev, Arnold J. Stromberg, Na Ren, Guiliang Tang, Qingwei Huang, Isidore Rigoutsos, Peter T. Nelson

Sanders-Brown Center on Aging Faculty Publications

MicroRNAs (miRNAs) are small regulatory RNAs that participate in posttranscriptional gene regulation in a sequence-specific manner. However, little is understood about the role(s) of miRNAs in Alzheimer's disease (AD). We used miRNA expression microarrays on RNA extracted from human brain tissue from the University of Kentucky Alzheimer's Disease Center Brain Bank with near-optimal clinicopathological correlation. Cases were separated into four groups: elderly nondemented with negligible AD-type pathology, nondemented with incipient AD pathology, mild cognitive impairment (MCI) with moderate AD pathology, and AD. Among the AD-related miRNA expression changes, miR-107 was exceptional because miR-107 levels decreased significantly even in patients with …

Comparative Secretome Analysis Suggests Low Plant Cell Wall Degrading Capacity In Frankia Symbionts, Juliana E. Mastronunzio, Louis S. Tisa, Philippe Normand, David R. Benson

Molecular, Cellular & Biomedical Sciences

Background: Frankia sp. strains, the nitrogen-fixing facultative endosymbionts of actinorhizal plants, have long been proposed to secrete hydrolytic enzymes such as cellulases, pectinases, and proteases that may contribute to plant root penetration and formation of symbiotic root nodules. These or other secreted proteins might logically be involved in the as yet unknown Molecular interactions between Frankia and their host plants. We compared the genome-based secretomes of three Frankia strains representing diverse host specificities. Signal peptide detection algorithms were used to predict the individual secretomes of each strain, and the set of secreted proteins shared among the strains, termed the core …

Opportunities And Roadblocks In Utilizing Forages And Small Grains For Liquid Fuels, Gautam Sarath, Robert B. Mitchell, S. E. Sattler, Deanna L. Funnell, Jeffrey F. Pedersen, Robert A. Graybosch, Kenneth P. Vogel

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

This review focuses on the potential advantages and disadvantages of forages such as switchgrass (Panicum virgatum), and two small grains: sorghum (Sorghum bicolor), and wheat (Triticum aesitvum), as feedstocks for biofuels. It highlights the synergy provided by applying what is known from forage digestibility and wheat and sorghum starch properties studies to the biofuels sector. Opportunities therefore, exist to improve biofuel qualities in these crops via genetics and agronomics. In contrast to cereal crops, switchgrass still retains tremendous exploitable genetic diversity, and can be specifically improved to Wt a particular agronomic, management, and conversion …

Differential Role Of Nadp+ And Nadph In The Activity And Structure Of Gdp-D-Mannose 4,6-Dehydratase From Two Chlorella Viruses, Floriana Fruscione, Laura Sturla, Garry Duncan, James L. Van Etten, Paola Valbuzzi, Antonio De Flora, Eleonopra Di Zanni, Michela Tonetti

James Van Etten Publications

GDP-D-mannose 4,6-dehydratase (GMD) is a key enzyme involved in the synthesis of 6-deoxyhexoses in prokaryotes and eukaryotes. Paramecium bursaria chlorella virus-1 (PBCV-1) encodes a functional GMD, which is unique among characterized GMDs because it also has a strong stereospecific NADPH-dependent reductase activity leading to GDP-D-rhamnose formation (Tonetti, M., Zanardi, D., Gurnon, J., Fruscione, F., Armirotti, A., Damonte, G., Sturla, L., De Flora, A., and Van Etten, J.L. (2003) J. Biol. Chem. 278, 21559–21565). In the present study we characterized a recombinant GMD encoded by another chlorella virus, Acanthocystis turfacea chlorella virus 1 (ATCV-1), demonstrating that it has the expected dehydratase …

Plant Succession On Gopher Mounds In Western Cascade Meadows: Consequences For Species Diversity And Heterogeneity, Chad C. Jones, Charles B. Halpern, Jessica Niederer

Botany Faculty Publications

Pocket gophers have the potential to alter the dynamics of grasslands by creating mounds that bury existing vegetation and locally reset succession. Gopher mounds may provide safe sites for less competitive species, potentially increasing both species diversity and vegetation heterogeneity (spatial variation in species composition). We compared species composition, diversity and heterogeneity among gopher mounds of different ages in three montane meadows in the Cascade Range of Oregon. Cover of graminoids and forbs increased with mound age, as did species richness. Contrary to many studies, we found no evidence that mounds provided safe sites for early successional species, despite their …

Drought And Salinity Tolerance In Common Agrostis Species., Carol Auer, Collin Ahrens

Plant Science Presentations and Proceedings

Our research examines plant gene flow and the impacts from environmental release of genetically-modified plants. Plant gene flow is a natural process that occurs when pollen from one plant lands on the flower of another plant and produces a hybrid offspring. Gene flow can produce hybrid offspring with new traits that could change the ability of the plant to survive and spread. If hybrid offspring have some advantage in the environment, they could become invasive and/or affect other components of our ecosystems. In the near future, the federal government may approve the use of a genetically engineered herbicide-resistant (HR) Agrostis …

If Hybrids Go Wrong: Assessing Potential Environmental Risk From Release Of Herbicide-Resistant Creeping Bentgrass (Agrostis)., Carol Auer, Collin Ahens

Plant Science Presentations and Proceedings

Genetically-modified (GM) plants need to be assessed for their benefits and risks before they are released into the environment. At present, GM grasses are being developed to improve sports turf and biofuels crops (e.g. switchgrass). How will genetic engineering of perennial grasses alter the distribution of these grasses in natural areas and managed landscapes? Can we use research data to predict future gene flow, weediness, or invasion? These are some of the important questions in ecological risk assessment of GM perennial grasses. We have initiated five research projects to characterize gene flow and potential ecological risk from herbicide-resistant (HR) creeping …

A Watershed Analysis Of Pattee Pond: Implications For Water Quality And Land Use Management, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Pattee Pond (2008, 1992)

The Colby Environmental Assessment Team (CEAT) investigated the impact of land use patterns on the water quality of Pattee Pond in Winslow, Maine, during the summer and fall of 2008. Physical, chemical, and biological characteristics of water quality were analyzed to evaluate the current health of the lake. Data collected were compared with previous studies conducted by the Maine Department of Environmental Protection (DEP) and CEAT to examine changes in water quality and land use over time. Trends in Pattee Pond water quality suggest an improvement since the 1970s. However, the lake is still experiencing algal blooms resulting from phosphorus …

A Dynamic Lagrangian, Field-Scale Model Of Dust Dispersion From Agriculture Tilling Operations, Thomas H. Meyer

Department of Natural Resources and the Environment Articles

Dust exposure in and near farm fields is of increasing concern for human health and may soon be facing new emissions regulations. Dust plumes of this nature have rarely been documented due to the unpredictable nature of the dust plumes and the difficulties of accurately sampling the plumes. This article presents a dynamic random‐walk model that simulates the field‐scale PM10 (particle diameter <10 >um) dust dispersion from an agriculture disking operation. The major improvements over traditional plume models are that it can simulate moving sources and plume meander. The major inputs are the friction velocity (u*), wind direction in the simulation …

What Limits Fire? An Examination Of Driver's Of Burnt Area In Southern Africa, Sally Archibald, David P. Roy, Brian W. Van Wilgen, Robert J. Scholes

GSCE Faculty Publications

The factors controlling the extent of fire in Africa south of the equator were investigated using moderate resolution (500 m) satellite-derived burned area maps and spatial data on the environmental factors thought to affect burnt area. A random forest regression tree procedure was used to determine the relative importance of each factor in explaining the burned area fraction and to address hypotheses concerned with human and climatic influences on the drivers of burnt area. The model explained 68% of the variance in burnt area. Tree cover, rainfall in the previous 2 years, and rainfall seasonality were the most important predictors. …

Plant Terpenoids: Applications And Future Potentials, Sam Zwenger, Chhandak Basu

Biological Sciences Faculty Publications

The importance of terpenes in both nature and human application is difficult to overstate. Basic knowledge of terpene and isoprene biosynthesis and chemistry has accelerated the pace at which scientists have come to understand many plant biochemical and metabolic processes. The abundance and diversity of terpene compounds in nature can have ecosystem-wide influences. Although terpenes have permeated human civilization since the Egyptians, terpene synthesis pathways are only now being understood in great detail. The use of bioinformatics and molecular databases has largely contributed to analyzing exactly how and when terpenes are synthesized. Additionally, terpene synthesis is beginning to be understood …

Seed Predators Of Canada Milk-Vetch And Their Parasitoids, Arvid Boe, Paul J. Johnson

Native Plant Focused Publications

Canada milk-vetch (Astragalus canadensis L.), North America’s most widespread species of Astragalus, is important for herbivores and granivores in natural ecosystems but suffers heavy seed losses to bruchids and curculionids. Our objectives were: (1) compile a species inventory and describe life histories of insects associated with seed production in Canada milk-vetch, and (2) determine frequencies of pod predation and primary parasitism in Canada milk-vetch. The seed predators were Acanthoscelides perforatus (Horn) and Tychius liljebladi Blatchley. Frequency of pod predation varied between two plant populations (46 and 70%) and between A. perforatus (37 %) and T. liljebladi (21 %). The primary …

Competitive Abilities Of Native Grasses And Non-Native (Bothriochloa Spp.) Grasses, Cheryl D. Schmidt, Rob Channell Ph.D., Karen R. Hickman, Keith Harmoney, William J. Stark Ph.D.

Biological Sciences Faculty Publications

Old World Bluestems (OWB), introduced from Europe and Asia in the 1920s, recently have begun to raise concerns in the Great Plains. Despite suggestion in the late 1950s that OWB were weedy and negatively impacted biological diversity, they were widely introduced throughout the Great Plains for agricultural purposes. Anecdotal evidence suggests that OWB exhibit invasive characteristics that promote competitive exclusion of native species. The objective of our study was to quantify the competitive abilities of two OWB species (Caucasian bluestem; Bothriochloa bladhii (Retz.) S. T. Blake (= Bothriochloa caucasica (Trin.) C. E. Hubb.) and yellow bluestem; Bothriochloa ischaemum (L.) Keng) …

Simulated Effects Of Various Environmental Management Practices On Water Consumption In Open And Confined Greenhouse Systems, Ilhami Yildiz, D. P. Stombaugh

BioResource and Agricultural Engineering

The objective of this study was to evaluate the effects of relative humidity, light management, minimum ventilation rates, CO₂ enrichment and canopy size on water consumption in three different greenhouse systems (conventional, open heat pump, and confined heat pump) in winter, spring, and summer months. Using different relative humidity set points resulted in almost the same relative humidity regimes within the confined greenhouse system, resulting in similar transpiration rates. No difference was observed in transpiration rates in the open system in winter either, because the inside relative humidity levels never reached the 70% and 80% set points. Some differences …
