Marian Library/IMRI Faculty Publications
S. Fred Prince, a botanical illustrator and amateur scientist, is a largely unknown artist whose work on the American landscape demonstrates his eligibility to be considered in the lineage of self-taught illustrator-naturalists such as Mark Catesby and Genevieve Jones. In this article, we present a survey of extant Prince materials identified at time of writing, describing their contents and physical characteristics. Beyond this survey and description, we also provide a biographical sketch and timeline of Prince's life.
Characterization Of A Novel Mitochondrial Plasmid In Brassica, 2017 University of Nebraska - Lincoln
Characterization Of A Novel Mitochondrial Plasmid In Brassica, Mackenzie Strehle
UCARE Research Products
Possessing some of the largest and most complex genomes of any eukaryotic organelles, plant mitochondria are notorious for their rapidly rearranging genetic framework. In addition to containing a large and complex mitochondrial genome, the mitochondria of several plants in the genus Brassica have also been shown to contain an independent, self-replicating linear plasmid. Interestingly, the plasmid appears to be able to move independently between the cytoplasm and the mitochondria, and it can be paternally inherited, unlike the rest of the mitochondrial genome. The plasmid also has features similar to those of adenoviruses, including terminal inverted repeats and covalently bound proteins ...
Surface-Soil Properties Of Alder Balds With Respect To Grassy And Rhododendron Balds On Roan Mountain, North Carolina—Tennessee, 2017 East Tennessee State University
Surface-Soil Properties Of Alder Balds With Respect To Grassy And Rhododendron Balds On Roan Mountain, North Carolina—Tennessee, James T. Donaldson, Zachary C. Dinkins, Foster Levy, Arpita Nandi
We analyzed soils in Alder Bald, Grassy Bald, and Rhododendron Bald communities on Roan Mountain to infer the influence of vegetation on soil and to help guide management strategies. In all vegetation types, soils were acid (pH = 4–5) sandy loams. We found vegetation-associated differences for organic content, cation exchange capacity, acidity, two plant macronutrients (K, Mg), and three cations (Fe, Na, Zn). We predicted that nitrogen compounds would be highest in the Alder Bald because Alnus viridis ssp. crispa (Green Alder) can harbor nitrogen-fixing bacteria. Organic content was highest at the alder-bald sites, ammonium was similar among vegetation types ...
Pattern And Rate Of Decline Of A Population Of Carolina Hemlock (Tsuga Caroliniana Engelm.) In North Carolina, 2017 East Tennessee State University
Pattern And Rate Of Decline Of A Population Of Carolina Hemlock (Tsuga Caroliniana Engelm.) In North Carolina, Foster Levy, Elaine S. Walker
We monitored a population of Carolina Hemlocks in northwestern North Carolina for four years to examine the rate and pattern of decline in response to infestation by Adelges tsugae (Hemlock Woolly Adelgid). Our yearly census of hemlock condition and severity of the adelgid infestation included trees of all sizes. We estimated declines in condition as the portions of the leaf canopy that were lost. Initially, infestation occurred throughout the population but was severe in only a small cluster of individuals. Within 1 year, the area of severe infestation increased in size to encompass 48% of the population. In another region ...

Deidamia Inscriptum (Lettered Sphinx Moth) Caterpillars Feeding On Oxydendrum Arboreum (Sourwood) And Their Predation By Black Bears In Northeast Tennessee, Foster Levy, David L. Wagner, Elaine S. Walker
An outbreak of Deidamia inscriptum (Lettered Sphinx Moth) caterpillars was noted in northeast Tennessee where Oxydendrum arboreum (Sourwood) trees were defoliated. Nearly all published literature and online resources list only plants in the grape family (Vitaceae) as larval food plants. Food-plant preference trials using fresh leaves of 3 woody plant species showed that Deidamiacaterpillars from this region had a preference for Sourwood over Parthenocissus quinquefolia(Virginia Creeper), and rejected Acer rubrum (Red Maple), a non-host species. Ursus americanus(Black Bear) were feeding on the caterpillars as evidenced by bent and broken Sourwood saplings bearing claw marks and by abundant ...
Control Of Glyphosate-Resistant Common Ragweed (Ambrosia Artemisiifolia L.) In Glufosinate-Resistant Soybean [Glycine Max (L.) Merr], 2017 University of Nebraska-Lincoln
Control Of Glyphosate-Resistant Common Ragweed (Ambrosia Artemisiifolia L.) In Glufosinate-Resistant Soybean [Glycine Max (L.) Merr], Ethann R. Barnes, Stevan Z. Knezevic, Peter H. Sikkema, John L. Lindquist, Amit J. Jhala
Agronomy & Horticulture -- Faculty Publications
Common ragweed emerges early in the season in Nebraska, USA and is competitive with soybean; therefore, preplant herbicides are important for effective control. Glyphosate has been used as a preplant control option; however, confirmation of glyphosate-resistant (GR) common ragweed in Nebraska necessitates evaluating other herbicide options. The objectives of this study were to (1) evaluate the efficacy of preplant (PP) herbicides followed by (fb) glufosinate alone or in tank-mixture with imazethapyr, acetochlor, or S-metolachlor applied post-emergence (POST) for control of GR common ragweed in glufosinate-resistant soybean; (2) their effect on common ragweed density, biomass, and soybean yield; and (3) the ...

Pinching And Spacing Effects On Cut Sunflower (Helianthus Annuus) Production In East Texas, 2017 Stephen F Austin State University
Pinching And Spacing Effects On Cut Sunflower (Helianthus Annuus) Production In East Texas, Rebecca B. Burnett
Electronic Theses and Dissertations
Three experiments evaluated pinching and spacing on Helianthus annuus in East Texas to determine their effects on growth and development. Experiment 1 was designed to determine the effects of pinching nodes 1, 2, 3, or 4 on ‘Pro Cut Gold’ sunflowers. Results from experiment 1 showed non-pinched plants produced marketable stem lengths and flower sizes, while pinched plants’ stem length, stem diameter, flower diameter, and disk diameter decreased compared to the non-pinched plants. The objective for experiment 2 was to evaluate pinching and spacing treatments on ‘Pro Cut Gold’ sunflowers. All spacings for non-pinched plants in experiment 2 produced marketable ...
Another Route For Amino Acid Production?: Reverse Genetic Probing For A Functional Cytosolic Shikimate Pathway In Plants, Gabrielle C. Buck, Joseph Lynch, Natalia Dudareva
The Summer Undergraduate Research Fellowship (SURF) Symposium
The shikimate pathway is a metabolic pathway that produces the three aromatic amino acids—phenylalanine, tryptophan, and tyrosine—which are essential to human diets and necessary for many plant functions. Consequently, the shikimate pathway is commonly targeted for antibiotic and herbicide strategies as well as genetic engineering in several fields. This pathway is known to be localized in the plastids, or double membrane-bound organelles, of plant cells; however, there is enzymatic evidence of another shikimate pathway in the cell fluid, or cytosol. To determine whether a complete cytosolic shikimate pathway exists, we used a modified gene for the first enzyme ...

Developing A Plant Virus-Based Expression System For The Expression Of Vaccines Against Porcine Reproductive And Respiratory Syndrome Virus, Hong Hanh Tran
Electronic Thesis and Dissertation Repository
Virus-based expression systems have been widely exploited for the production of recombinant proteins in plants during the last three decades. Advances in technology have boosted scale-up manufacturing of plant-made pharmaceuticals to high levels, via the complementation of transient expression and viral vectors. This combination allows proteins of interest to be produced in plants within a matter of days and thus, is well suited for the development of plant-made vaccines or therapeutics against emerging infectious diseases and potential bioterrorism agents. Several plant-based products are currently in varying stages of clinical development. To investigate the viability of virus-based expression systems for plant-made ...

Life Behind The Wall: Sensing Mechanical Cues In Plants, 2017 Washington University in St Louis
Life Behind The Wall: Sensing Mechanical Cues In Plants, Olivier Hamant, Elizabeth S. Haswell
Biology Faculty Publications & Presentations
There is increasing evidence that all cells sense mechanical forces in order to perform their functions. In animals, mechanotransduction has been studied during the establishment of cell polarity, fate, and division in single cells, and increasingly is studied in the context of a multicellular tissue. What about plant systems? Our goal in this review is to summarize what is known about the perception of mechanical cues in plants, and to provide a brief comparison with animals.
Dissecting The Genetic Basis Of Salt Tolerance In Rice (Oryza Sativa), 2017 University of Nebraska-Lincoln
Dissecting The Genetic Basis Of Salt Tolerance In Rice (Oryza Sativa), Malachy Thomas Campbell
Theses, Dissertations, and Student Research in Agronomy and Horticulture
Excessive salt is a major factor limiting crop productivity. Rice is an important food crop worldwide, and provides a major source of calories for billions of people in tropical and subtropical developing countries. In many regions throughout Southeast Asia, rice is grown in low-lying coastal regions, which are prone to ingress by seawater. Rice is highly sensitive to salt stress, with mild salinity resulting in large reductions in yield. Improving salt tolerance in rice is essential for ensuring food security for many individuals throughput the developing world.
In this work, the overall goals were to characterize a diverse collection of ...
The Interacting Roles Of Climate, Soils, And Plant Production On Soil Microbial Communities At A Continental Scale, 2017 John Carroll University
The Interacting Roles Of Climate, Soils, And Plant Production On Soil Microbial Communities At A Continental Scale, Rebecca E. Drenovsky
2017 Faculty Bibliography
Soil microbial communities control critical ecosystem processes such as decomposition, nutrient cycling, and soil organic matter formation. Continental scale patterns in the composition and functioning of microbial communities are related to climatic, biotic, and edaphic factors such as temperature and precipitation, plant community composition, and soil carbon, nitrogen, and pH. Although these relationships have been well explored individually, the examination of the factors that may act directly on microbial communities vs. those that may act indirectly through other ecosystem properties has not been well developed. To further such understanding, we utilized structural equation modeling (SEM) to evaluate a set of ...
Twenty-First Century Climate Change And Submerged Aquatic Vegetation In A Temperate Estuary: The Case Of Chesapeake Bay, Thomas M. Arnold, Richard C. Zimmerman, Katharina A. M. Engelhardt, J. Court Stevenson
Faculty and Staff Publications By Year
Introduction: The Chesapeake Bay was once renowned for expansive meadows of submerged aquatic vegetation (SAV). However, only 10% of the original meadows survive. Future restoration efforts will be complicated by accelerating climate change, including physiological stressors such as a predicted mean temperature increase of 2–6°C and a 50–160% increase in CO2 concentrations.
Outcomes: As the Chesapeake Bay begins to exhibit characteristics of a subtropical estuary, summer heat waves will become more frequent and severe. Warming alone would eventually eliminate eelgrass (Zostera marina) from the region. It will favor native heat-tolerant species such as widgeon grass (Ruppia ...
Effects Of Mycorrhizal Fungi On Vigna Radiata Growth In Soil Differing In Fertilizer Concentration, 2017 Chinese International School Hong Kong
Effects Of Mycorrhizal Fungi On Vigna Radiata Growth In Soil Differing In Fertilizer Concentration, Ming Sum Jessica Cheng
Pursuit - The Journal of Undergraduate Research at the University of Tennessee
Mycorrhizal fungi form mutualistic relationships with the roots of some plants, allowing the plant access to nutrients and minerals while the fungi obtain food from the plant. Given that this relationship is beneficial to the plant, this paper investigates the nature of the impact of presence of mycorrhizal fungi on the growth of Vigna radiata (mung beans) in soil of differing chemical environments. Through comparing the stem lengths of plants seven days after germination, it is found that in soil with 0.0% fertilizer, the presence of locally collected, unclassified mycorrhizal fungi impacts the growth of Vigna radiata negatively; in ...

Photosynthesis And Shoot Health Of Five Birch And Four Alder Taxa After Drought And Flooding, William R. Graves, Mark A. Kroggel, Mark P. Widrlechner
William R Graves
Selection of under-used taxa of birches (Betula L.) and alders (Alnus Miller) for use in managed landscapes can be guided by information on their responses to moisture extremes in the root zone. Our objective was to compare the photosynthesis, leaf surface area, and subjective health ratings of eight relatively obscure birches and alders when treated with drought and flooding in a greenhouse. We also treated ‘Whitespire Sr.’ birch (Betula populifolia) to demonstrate responses of a cultivar common in the nursery trade. Plants used as controls were irrigated daily, whereas pots of flooded plants were immersed. All water was withheld from ...
Systematics Of Dirca (Thymelaeaceae) Based On Its Sequences And Issr Polymorphisms, 2017 Iowa State University
Systematics Of Dirca (Thymelaeaceae) Based On Its Sequences And Issr Polymorphisms, James A. Schrader, William R. Graves
William R Graves
The genus Dirca consists of three disjunct species of shrubs. Dirca palustris is found in the eastern United States and adjacent Canada; D, occidcntahs is Umited to six counties near the San Francisco Bay in California; and the recently discovered D, mcxicana is known from one isolated population in northeastern Mexico. The three species have been described and classified according to morphological characters, but the morphological evidence does not provide a clear assessment of the relationships among the species. Morphologically D. mexicana most closely resembles D. occidenlalis., but known biogeographical trends raise doubt regarding how the three species are interrelated ...
Alnus Maritima: A Rare Woody Species From The New World, 2017 Iowa State University
Alnus Maritima: A Rare Woody Species From The New World, James A. Schrader, William R. Graves
William R Graves
Although first introduced into cultivation in the 1870's and praised for its ornamental character, Alnus maritima (Marsh.) Muhl. ex Nutt. (seaside alder) remains a rare woody species with unrealised potential. The ornamental promise of A. maritima was first recognised by Thomas Meehan, an Englishman who emigrated to the United States (Philadelphia, Pa). In 1848 after serving for two years at the Royal Botanic Gardens, Kew, Mr. Meehan was best known as the publisher of Meehan's Monthly (1891- 1902) and as the author of The American Handbook of Ornamental Trees (1853) and The Native Flowers and Ferns of the ...
