Genetic And Phenotypic Variation Among Turkish Terrestrial Orchidspecies As Revealed By Rapd And Morphological Characteristics, Gülden Sandal Erzurumlu, Nusrat Sultana, Mehtap Vural, Sedat Serçe

Turkish Journal of Agriculture and Forestry

Terrestrial orchid species are natural sources of salep and a closely related group of plant species widely distributed throughout Turkey. The phylogenetic relationship among fourteen different tuber-producing orchid species was investigated after analyzing phenotypic and genetic variation within and among the natural population through fifteen morphometric traits and ten random amplified polymorphic DNA (RAPD) primer combinations. Statistical analyses (principal component analysis (PCA), principal coordinate analysis (PCoA), and cluster analysis) using the generated data identified taxonomic and genetic distance within the studied plant samples. The results of PCA from morphological traits show that there are no major groupings within and among …

Turkish Journal of Agriculture and Forestry

It is due to the lack of renewable fiber sources for industrial purposes that the need for finding available and alternative material has become imperative. Kenaf (Hibiscus cannabinus L.), a fast-growing industrial crop, would be a potential solution for valorizing salinized lands and/or soils irrigated with saline water. With the aim of selecting and valorizing salt-tolerant species with high fiber yields and industrial values, we launched the assessment of the performance of kenaf culture (var. Guangdong 743-2) under salinity constraints. Germination and vegetative stages were considered in the present study to better evaluate the whole life cycle of the species. …

Turkish Journal of Agriculture and Forestry

Banded herbicide applications with hooded field sprayers (HFS) provide safer applications in many crops. The aim of this paper is to show the effectiveness and safeness of selective and nonselective herbicide applications in a conventional sunflower production system (CSPS) using a combined hooded field sprayer (CHFS). Glyphosate interrow and aclonifen or quizalofop-P-ethyl intrarow were applied in fields cropped with nonglyphosate-resistant sunflower varieties in Ankara, Tekirdağ, and Tokat Provinces of Turkey in 2015 and 2016. In Ankara and Tekirdağ, glyphosate caused limited injury to sunflower at 28 days after treatment (DAT), and aclonifen created transient phytotoxicity in 2015. Glyphosate was applied …

Genetic Diversity Among Melon (Cucumis Melo L.) Accessionsrevealed By Morphological Traits And Issr Markers, Niyazi Guliyev, Saida Sharifova, Javid Ojaghi, Mehraj Abbasov, Zeynal Akparov

Turkish Journal of Agriculture and Forestry

The genetic relationships among 48 melon (Cucumis melo L.) genotypes collected from various parts of Azerbaijan were determined by comparing their phenotypic and molecular traits. Eleven agromorphological traits and 10 polymorphic inter-simple sequence repeat (ISSR) primers were used to define the genetic diversity. Principal component analysis grouped the agromorphological traits into the first four axes, describing 78% of the total variations. The highest genetic variation coefficient was found for yield per hectare (20.32%) and for fruit length (17.35%). Calculated heritability for yield was 0.96. The analysis of morphological traits grouped the accessions into four clusters. The 10 ISSR primers yielded …

Cereal Source And Microbial Consortia Of The Starter Culture Influence The Chemicalcomposition And Physicochemical Characteristics Of Boza, Mehli̇ka Borcakli, Tarik Öztürk, Erdem Yeşi̇lada

Turkish Journal of Agriculture and Forestry

Boza is a popular cereal-based traditional beverage particularly consumed during winter months in Balkan countries and Turkic societies. The present study aims to investigate the influence of different cereal sources and starter cultures used in the commercial production of boza on its chemical and microbiota compositions and physicochemical characteristics. Detailed experimentation has revealed that chemical compositions, i.e. carbohydrates (beta-glucans, starches), organic acids, vitamins, dietary fibers, proteins, fat, and minerals, along with physicochemical characteristics, are subject to significant differentiation depending upon the cereal types and microbial consortia of the starter culture used in boza production. These variations also influence the physicochemical …

Native Grass Cover Influences Forb Density In Cp-42 Pollinator Plantings, Alyssa Burgert, Laura Jackson

Undergraduate Student Work

In recent years, pollinator populations have greatly declined due to a large decrease in habitat. In order to combat this decline, government programs have provided farmers with incentives to convert cropland to pollinator habitat.¹ Farmers are required to plant at least 9 insect-pollinated species, with 3 species each blooming in early, middle and late summer. Any grasses must be native and comprise no more than 25% of the seed mix.² Because of the high cost of forb seed and relatively low cost of grasses, we aimed to evaluate the effectiveness of this seed mix strategy. We predicted that …

Rates And Patterns Of Evolution In A Duplicated Genome In The Family Catostomidae, Megann Michelle Schmidt

Honors Program Theses

Whole genome duplication (WGD) is a process in which the entire genome of an organism is duplicated, making redundant genes which are subject to unique evolutionary forces. Various modes of selection create different genetic fates such as retention of ancestral function, development of new function, or loss of function. Because of these differing fates, WGD is hypothesized to be a major driving force behind diversification. In this project, DNA sequences from fish species in the family Catostomidae were examined to observe patterns of evolution following a known WGD. Gene trees were generated for 179 loci to determine the amount of …

Effect Of Extracellular Atp On Cellular Actin Fibrils' Location And Characteristics, Dianna Huisman

Honors Program Theses

Epithelial cells lining secretory units and ducts of bovine mammary glands perform an important role in regulating movement of various macromolecules and whole cells during normal lactation and mastitis. During mastitis, host-and bacteria-produced substances can affect the “barrier” function of epithelial monolayers. One potential component is adenosine triphosphate (ATP). ATP likely interacts with P2X7, a purinergic receptor, in mediating some effects associated with mastitis including changes in cell permeability. The bovine mammary gland epithelial cell line, Mac-T cells, were examined for cytoskeletal changes as result of P2X7 interactions. Actin cytoskeletons were stained with phalloidin and effects were examined by fluorescent …

Correlation Between Wild Bee Populations And Vegetative Resources In The Conservation Reserve Program’S Pollinator Enhancement Plantings, Olivia Willoughby, Alyssa Burgert, Nathan Theel, Ai Wen

Undergraduate Student Work

Wild bee populations are in decline; and one of the main factors that caused this is habitat loss, which diminishes floral resources that bees utilize for nectar and pollen (Watanabe 2013)

The Conservation Reserve Program (CRP) aims to combat habitat loss by implementing ecological restorations that provide resources for a variety of different wildlife

In 2011, the CRP established a Pollinator Habitat Initiative called CP-42, which encompasses forbs and grasses to create adequate habitat for pollinators

A primary goal of this program is to enhance pollinator abundance and diversity

Comparison Of Two Levels Of Inpatient Dysphagia Treatment Dosages On Swallowing Outcomes, Paige Licht

Honors Program Theses

Current research reveals great variability in many aspects of service delivery for swallowing rehabilitation, including dosage or intensity of treatment. Therefore, there is a need to investigate the effects of treatment intensity on swallowing rehabilitation outcomes. The purpose of this study is to determine whether two levels of treatment intensity produce different patterns of swallowing recovery for inpatients with neurogenic dysphagia. Blinded analysis of pre- and post-treatment videofluoroscopic measures of swallowing were completed for six inpatients at the Rehabilitation Institute of Chicago who were previously randomized to one of two dysphagia exercise programs. One arm consisted of traditional 30-minute treatment …

Van Der Waals Interactions In Ultrafine Nanocellulose Aerogels, Byron John Fritch

Honors Program Theses

The purpose of this study was to establish methods of synthesizing various compositions of nanocellulose aerogels using a top-down ultrasonication synthesis approach. Quantifying the effect composition has on physical properties was also be of interest due to the lack of scientific literature over this material. Microscopic techniques and physical experiments were used to determine how the internal structure of the aerogel material varies with composition and how the internal structure effects the physical properties. The main driving factor behind this study was that not much current scientific literature can be found about how the ultrasonic process effects the nanocellulose aerogels. …

Prebiotic Potential Of Aerosols, Emma Rae Shipley

Honors Program Theses

A triple quadrupole gas chromatograpy mass spectrometer (GC/MS/QQQ) was used to determine prebiotic molecules of interest in plasma and photochemical aerosols. Glycolic acid was further studied using isotopically doped gases. Plasma and photochemical aerosol analogs were shown to have nucleobases and a few amino acids. Each type of aerosol was also the source of glycolic acid, a precursor to glycine. Using ¹⁸O doped CO, it was determined that contamination was not a source of oxygen in the samples. Using different combinations of ¹³C doped gases in 1:1 combinations of CO and CH₄, it was determined that …

• The CP-42 program provides cost share and an annual rental payment to farmers in order to establish native prairie species for pollinator habitat.

County NRCS technical staff make recommendations for seed mix to match the dominant soil moisture class in a parcel (e.g. dry, mesic, wet) with the appropriate plant species.

• There has been little to no research prior to the Biology SURP initiative to monitor …

Literature Review: Analyzing The Reasons Behind The Long-Standing Debate Of Evolution And Religion In America, Michelle Kathryn Matchell

Honors Program Theses

Evolution has been a widely studied and debated topic for centuries. Since the days of Greek philosophy, humans have been curious about the diversity of life and how it arose to what we see today. Interest in evolution flourished during the days of Charles Darwin when he and Alfred Russel Wallace developed the concept of natural selection. Now, evolution is an integral part of many scientific studies, especially genetics, developmental biology, geology, behavior studies and social sciences. According to Muhammad Ashraf, evolution can be considered ‘the cornerstone of modern science’ (Ashraf, 2016). On what would have been Darwin’s 201st birthday, …

Does Folic Acid Compete With Glutamic Acid At The Postsynaptic Membrane Nmda Receptor?, Amanda Nicole Koenig

Honors Program Theses

During the first month of a human pregnancy folic acid (FA) is vital to the closing of the neural tube. However, overconsumption of FA has been linked to the rise of Autism Spectrum Disorder (ASD), although this linkage is still under debate and testing. It has been hypothesized that the glutamate (GA) portion of FA may compete for binding to the N-methyl-d-aspartate receptor (NMDA-R) with the neurotransmitter glutamate, causing inhibited growth cone activity. In order to test this hypothesis, we cultured eight-day chick dorsal root ganglia (DRGs) and assessed parameters of neural development in the presence of FA, GA, or …

Floral Resource Dynamics For Pollinators In A Central Iowa Tallgrass Prairie Restoration, Lily Conrad, Ben Hoksch, Mark C. Myers

Undergraduate Student Work

Recently, native and managed colonies of pollinators, including bees, butterflies, and other insects, have experienced a largescale declines. In an effort to restore habitat for pollinators, the United States Department of Agriculture’s Farm Service Agency (FSA) created the CP-42 Pollinator Habitat conservation practice under the Conservation Reserve Program. This program pays private landowners to restore habitat for pollinator species with ecological and economic importance. To qualify for the program, CP-42 seed mixes must include:

• A minimum of 9 pollinator-friendly flowering plants,

• A minimum of three species in bloom during each of three seasonal periods (April-June 15, June 15-July, …

New Insights Into The "Manna From Heaven" Hypothesis, Clare Laubenthal

Honors Program Theses

Titan’s atmosphere is unique in that its atmospheric chemistry is thought to be similar to that of the Earth’s atmosphere during the Archean Era, when bacterial life dominated the Earth¹. Tholins form as a result of the radiation of organic gases by ultraviolet light. These molecules are considered alike to the prebiotic hazes that formed in the atmosphere of Earth during the Archean Era and which allowed for the eventual development of microbial life² . This study investigated whether Earth soil bacteria can grow, using laboratory created tholin analogs, or aerosols, as a nutrient source. This study …

Ruxolitinib Significantly Enhances In Vitro Apoptosis In Hodgkin Lymphoma And Primary Mediastinal B-Cell Lymphoma And Survival In A Lymphoma Xenograft Murine Model, Sanghoon Lee, Tishi Shah, Changhong Yin, Jessica Hochberg, Janet Ayello, Carmella Van De Ven, Mitchell S. Cairo

NYMC Faculty Publications

Hodgkin lymphoma (HL) and primary mediastinal B-cell lymphoma (PMBL) share similar molecular features by gene expression profiling. Frequent gains of chromosome 9p exhibit higher Janus Kinase 2 (JAK2) transcript levels with increased JAK2 activity, suggesting aberrant activity of JAK2 and STAT pathways. This signaling pathway alteration may in part play an important role in the pathogenesis and/or chemoradiotherapy resistance in HL and PMBL. Ruxolitinib is a potent and selective JAK1/JAK2 inhibitor, with activity against myeloproliferative neoplasms (MPNs) including those harboring the JAK2V617F mutation. We investigated the in vitro and in vivo efficacy of ruxolitinib and changes in downstream signaling pathways …

De Facto Parent And Nonparent Child Support Orders, Jeffrey A. Parness, Matthew L. Timko

Faculty Articles, Papers, and Other Scholarship

For ever so long U.S. state laws have recognized the federal constitutional right to “care, custody and control” of a child vested in the opposite sex married couple who bore the child of sex or in any formal adoptive parent. More recently this parental right has also been recognized for the opposite sex unmarried couple who bore the child of sex. And even more recently, U.S. state laws have recognized this parental right for some who did not engage in the sex leading to birth and for some where the children were born without sex. State laws have also increasingly …

Benefit Of Polyandry In A Monandrous Species When Females Mate With Already Mated Males, Bethia H. King

Faculty Articles, Papers, and Other Scholarship

Female mating frequency varies among animal taxa. A benefit to females of remating has usually been found, but almost all tests have been with polyandrous species. A species being monandrous does not guarantee that mating only once benefits the female, instead the monandry may result from sexual conflict, where her failure to remate benefits her mate, but not her. The parasitoid wasp Spalangia endius (Hymenoptera: Pteromalidae) is highly monandrous. Females do not benefit from either immediate or delayed remating when their first mate is virgin. However, some females are likely to mate with already mated males because sex ratios are …

Mating Status Effects On Sexual Response Of Males And Females In The Parasitoid Wasp Urolepis Rufipes., Bethia H. King, K.A. Miller

Faculty Articles, Papers, and Other Scholarship

Although mate preferences are most commonly examined in females, they are often found in both sexes. In the parasitoid wasp Urolepis rufipes, both female and male mating status affected certain aspects of sexual interactions. Female mating status mattered only in the later stages of mating. Males did not discriminate between virgin and mated females in terms of which they contacted or mounted first. However, once mounted, most virgin females were receptive to copulation, whereas very few mated females were. Whether a male’s mating status affected his own sexual response depended on the female’s ability to respond and the stage of …

Engineering A Molecular Missile For Pancreatic Cancer Detection: Vector Design, Sophia Castillo, Zhiwen Zhang

Helene Lafrance Library Undergraduate Research Award

Pancreatic cancer, though rare, is expected to be the second-leading cause of cancer-related death by 2030 (Rahib et al., 2014). CA 19-9 is currently the most widely used biomarker for pancreatic cancer detection, but detection of CA 19-9 relies on the use of monoclonal antibodies, a technology that entails an expensive, lengthy, and ethically problematic manufacturing process. This paper presents the design of a DNA vector that can be used to program E. coli to produce a “molecular missile” that targets CA 19-9. Through the site-specific incorporation of an unnatural amino acid (L-DOPA), this peptide can be engineered to bind …
