Compositional Trends And Spatial Patterns Over A Quarter Century: Forest Dynamics Of Dobbs Park, Indiana, Nancy Hoalst Pullen

All-Inclusive List of Electronic Theses and Dissertations

Thirty-five permanent plots were reexamined to identify and describe the spatial and temporal characteristics of Dobbs Park, an isolated old-growth forest stand in westcentral Indiana. The 3.6 ha stand was resurveyed in summer 2000, with all stems greater than 10 cm dbh measured, and accessions and deaths recorded. The results are compared to original data collected in summer 1974, with compositional and spatial patterns identified via GIS and spatial analysis. The stand has declined slightly in density from 342 stems/ha to 333.15 stems/hectare (-2.6%) while basal area (dominance) for the stand has increased from 23.6 m2/ha to 25.8 m2/ha (+8.8%) …

The Pollinator Fauna Of Two Spring Wildflowers Of Midwestern Deciduous Forest, Erigenja Bulbosa And Claytonia Virginica, Robert P. Jean

All-Inclusive List of Electronic Theses and Dissertations

Eastern deciduous forests have spectacular spring floral display and a diverse array of insect pollinators. From March to May, some 20-25 species of understory herbs flower in west-central Indiana. I focused on the earliest species to bloom, Erigenia bulbosa (Apiaceae), and the most abundant, Claytonia virginica (Portulacaceae), which flowers immediately after Erigenia. l characterized insect visitor assemblages in terms of species richness and relative abundance, and measured visitation rates. For Erigenia (Chapter 1), I asked whether early flowering was necessarily associated with pollinator scarcity. I examined six sites in 2000 and resampled three of these in 2001. Erigenia attracted 10 …

Uses Of Antimicrobials In Plant Agriculture, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

Bacterial diseases of plants are less prevalent than diseases caused by fungi and viruses. Antimicrobials for prophylactic treatment of bacterial diseases of plants are limited in availability, use, and efficacy, and therapeutic use is largely ineffective. Most applications are by spray treatments in orchards. Monitoring and surveillance for drug resistance are not routinely done. In the United States, data on use of antimicrobials for treatment of bacterial diseases of plants are limited to streptomycin and oxytetracycline. Resistance to streptomycin has become widespread among bacterial phytopathogens; no resistance among these bacteria has yet been reported for oxytetracycline. No human health effects …

Evapotranspiration Using A Satellite-Based Surface Energy Balance With Standardized Ground Control, Ricardo Trezza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study evaluated the potential of using the Surface Energy Balance Algorithm for Land (SEBAL) as a means for estimating evapotranspiration (ET) for local and regional scales in Southern Idaho. The original SEBAL model was refined during this study to provide better estimation of ET in agricultural areas and to make more reliable estimates of ET from other surfaces as well, including mountainous terrain. The modified version of SEBAL used in this study, termed as SEBAL_ID (lD stands for Idaho) includes standardization of the two SEBAL "anchor" pixels, the use of a water balance …

1080 Summary Information, Department Of Agriculture, Western Australia, Department Of Conservation And Land Management, Western Australia, Department Of Health, Western Australia

Biosecurity research reports

Fluoroacetate, the active ingredient of 1080, occurs naturally in toxic plants in Australia, South Africa, and South America. Manufactured I080 underpins most vertebrate pest control programs in Australia and New Zealand. Fluoroacetate occurs naturally in about 40 plant species in Australia with most of these plants restricted to the south-west of WA.

I080 was introduced to rabbit control programs in the early 1950s and therefore has a long history of proven effectiveness and safety in Australia. There have been few repo1ted problems associated with human safety, environmental persistence, bioaccumulation or impact on populations of non-target species.

In particular, I080 baits …

Characterization Of Fro1, A Pea Ferric-Chelate Reductase Involved In Root Iron Acquisition, Brian M. Waters, Dale G. Blevins, David J. Eide

Department of Agronomy and Horticulture: Faculty Publications

To acquire iron, many plant species reduce soil Fe(III) to Fe(II) by Fe(III)-chelate reductases embedded in the plasma membrane of root epidermal cells. The reduced product is then taken up by Fe(II) transporter proteins. These activities are induced under Fe deficiency. We describe here the FRO₁ gene from pea (Pisum sativum), which encodes an Fe(III)-chelate reductase. Consistent with this proposed role, FRO₁ shows similarity to other oxidoreductase proteins, and expression of FRO₁ in yeast conferred increased Fe(III)-chelate reductase activity. Furthermore, FRO₁ mRNA levels in plants correlated with Fe(III)-chelate reductase activity. Sites of FRO_{1 …}

Accumulation Of Microbial Biomass Within Particulate Organic Matter Of Aging Golf Greens, Mine Kerek, Rhae A. Drijber, William L. Powers, Robert C. Shearman, Roch E. Gaussoin, Anne Streich

Department of Agronomy and Horticulture: Faculty Publications

Microbial biomass (MB) is a key variable controlling soil organic matter dynamics in soil. Currently, there is little information on the amount and significance of MB in highly managed golf greens. Our objective was to determine the amount and distribution of MB within soil structural components of golf greens and its relationship to the location of organic substrates. During 1996, 47 greens were sampled from 12 golf courses within Nebraska (USA). Microbial biomass, determined as extractable lipid phosphate on field-moist soils, increased linearly with age of green (Y = 19.39 + 3.54x; r² = 0.87, P = 0.001). In …

Isolation And Characterization Of Endophytic Colonizing Bacteria From Agronomic Crops And Prairie Plants, Denise K. Zinniel, Patricia A. Lambrecht, N. Beth Harris, Zhengyu Feng, Daniel Kuczmarski, Phyllis Higley, Carol A. Ishimaru, Alahari Arunakumari, Raul G. Barletta, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

Endophytic bacteria reside within plant hosts without causing disease symptoms. In this study, 853 endophytic strains were isolated from aerial tissues of four agronomic crop species and 27 prairie plant species. We determined several phenotypic properties and found approximately equal numbers of gram-negative and gram-positive isolates. In a greenhouse study, 28 of 86 prairie plant endophytes were found to colonize their original hosts at 42 days postinoculation at levels of 3.5 to 7.7 log₁₀ CFU/g (fresh weight). More comprehensive colonization studies were conducted with 373 corn and sorghum endophytes. In growth room studies, none of the isolates displayed pathogenicity, …

The Effect Of Hydration On Stratification Efficiency Of Peach And Apple Seeds, Bryan E. Dayton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Manipulating bud dormancy in temperate fruit trees could reduce fruit loss due to early spring frosts. The relationship between moisture content and dormancy could provide a tool to better understand and ultimately manipulate the biochemical process of bud dormancy. Seeds have historically been used in research studies to predict bud dormancy because they have similar dormancy requirements and are easier to use. This study was conducted to quantify the relationship between seed water content and stratification efficiency for dormancy release. Seeds of peach, Prunus persica cv. 'Johnson Elberta,' and apple, Malus domestica cv. 'Golden Delicious,' were hydrated in vitro to …

Survival Of And Herbivore Damage To A Cohort Of Quercus Rubra Planted Across A Forest-Old-Field Edge, Scott J. Meiners, Matthew J. Matinkovic

Faculty Research & Creative Activity

Forest edges are known to affect plant community composition and habitat use by animals. However, the direct influence of edges in determining patterns of tree regeneration is poorly understood. Survival of and herbivore damage to Quercus ruln-a seedlings were experimentally determined for seedlings planted across a forest--old-field edge gradient. Seedling survival was lowest inside the forest ( 1%), intermediate at the edge (25%) and highest within the old-field portion of the gradient (49%). Deer herbivory decreased with increasing distance into the old field. Seedling survival increased under Rosa multiflora and decreased in plots with mammalian herbivory. Seedling height was significantly …

Pyruvate,Orthophosphate Dikinase In Leaves And Chloroplasts Of C3 Plants Undergoes Light-/Dark- Induced Reversible Phosphorylation, Chris J. Chastain, Jason P. Fries, Julie A. Vogel, Christa L. Randklev, Adam P. Vossen, Sharon K. Dittmer, Erin E. Watkins, Lucas J. Fiedler, Sarah A. Wacker, Katherine Meinhover, Gautam Sarath, Raymond Chollet

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

Pyruvate,orthophosphate (Pi) dikinase (PPDK) is best recognized as a chloroplastic C₄ cycle enzyme. As one of the key regulatory foci for controlling flux through this photosynthetic pathway, it is strictly and reversibly regulated by light. This light/dark modulation is mediated by reversible phosphorylation of a conserved threonine residue in the active-site domain by the PPDK regulatory protein (RP), a bifunctional protein kinase/phosphatase. PPDK is also present in C₃ plants, although it has no known photosynthetic function. Nevertheless, in this report we show that C₃ PPDK in leaves of several angiosperms and in isolated intact spinach (Spinacia …

Herbicide Evaluation In Arkansas Rice 2000, Ron Talbert, Ford Baldwin, Ken Smith, David Gealy, Eric Scherder, Mike Lovelace, Nathan Buehring, Marilyn Mcclelland

Arkansas Agricultural Experiment Station Research Series

With the widespread development of resistance to propanil by barnyardgrass, the major weed in rice, research has been intensified in recent years to develop alternative weed control technology to the repeated use of propanil. The use of herbicides is economically important for production of rice. Field experiments are conducted annually in Arkansas to evaluate the activity of developmental and commercial herbicides for selective control of barnyardgrass and other weeds in rice. These experiments serve both industry and Arkansas agriculture by providing information on the selectivity of herbicides still in the developmental stage and by comparing the activity of these new …

The Shca Protein Is A Molecular Chaperone That Assists In The Secretion Of The Hoppsya Effector From The Type Iii (Hrp) Protein Secretion System Of Pseudomonas Syringae, Karin V. Van Dijk, Vincent C. Tam, Angela R. Records, Tanja Petnicki-Ocwieja, James R. Alfano

Center for Plant Science Innovation: Faculty Publications

Pseudomonas syringae uses a type III protein secretion system encoded by the Hrp pathogenicity island (Pai) to translocate effector proteins into plant cells. One of these effector proteins is HopPsyA. A small open reading frame (ORF), named shcA, precedes the hopPsyA gene in the Hrp Pai of P. s. syringae 61. The predicted amino acid sequence of shcA shares general characteristics with chaperones used in type III protein secretion systems of animal pathogens. A functionally non-polar deletion of shcA in P. s. syringae 61 resulted in the loss of detectable HopPsyA in supernatant fractions, consistent with ShcA acting as a …

Phylogenetic Relationships, Strain Diversity And Biogeography Of Tritimoviruses, Frank Rabenstein, Dallas L. Seifers, Jorg Schubert, Roy C. French, Drake C. Stenger

Department of Plant Pathology: Faculty Publications

North American and Eurasian isolates of Wheat streak mosaic virus (WSMV; genus Tritimovirus) and Oat necrotic mottle virus (ONMV; genus Rymovirus) were examined. Nine WSMV isolates differentially infected oat, barley, inbred maize line SDp2 and sorghum line KS56. The WSMV isolates clustered into groups based on phylogenetic analyses of the capsid protein (CP) cistron and flanking regions. WSMV isolates from the United States (US) and Turkey were closely related, suggesting recent movement between continents. Although more divergent, WSMV from Iran (WSMV-I) also shared a most recent common ancestor with the US and Turkish isolates. Another group of WSMV …

Golden Rice: A Case Study In Intellectual Property Management And International Capacity Building, Stanley P. Kowalski, R. David Kryder

Law Faculty Scholarship

In order for agricultural biotechnology (agri-biotech) to play a larger role in the development of sustainable agricultural systems, intellectual property (IP) rights management must be addressed. These issues are not limited to developing countries. With increased globalization, the management of agri-biotech IP rights affects both developing and industrialized countries. In industrialized countries, for example, IP rights risk management entails protection of inventions via strong patent portfolios. For developing countries, IP rights risk management includes the acquisition of rights requisite for the use of inventions essential to the basic welfare of the population. Strategies are needed to bridge these disparate IP …

Agroecosystems, Nitrogen-Use Efficiency, And Nitrogen Management, Kenneth G. Cassman, Achim R. Dobermann, Daniel T. Walters

Department of Agronomy and Horticulture: Faculty Publications

The global challenge of meeting increased food demand and protecting environmental quality will be won or lost in cropping systems that produce maize, rice, and wheat. Achieving synchrony between N supply and crop demand without excess or deficiency is the key to optimizing trade-offs amongst yield, profit, and environmental protection in both large-scale systems in developed countries and small-scale systems in developing countries. Setting the research agenda and developing effective policies to meet this challenge requires quantitative understanding of current levels of N-use efficiency and losses in these systems, the biophysical controls on these factors, and the economic returns from …
