Inoculation With Bacillus Licheniformis Mh48 To Improve Camellia Japonicaseedling Development In Coastal Lands, Hyun-Gyu Park, Min-Hae Jeong, Young-Sang Ahn
Turkish Journal of Agriculture and Forestry
This study aimed to determine the promotion of the growth and nutrient uptake of Camellia japonica seedlings in coastal lands by bacterial inoculation. Soil salinity reduces plant growth and development in coastal areas due to the osmotic stress that perturbs nutrient uptake. The soil electrical conductivity at the sites of this study ranged from 1.02 to 1.89 dS m-1. Application of chemical fertilizer resulted in the limited uptake of nutrients in seedlings under saline conditions as well as a low nutrient content in the soil caused by leaching, with no significant influence on the growth of the seedlings. However, Bacillus …

Effects Of Mepiquat Chloride Applications On Non-Oilseed Sunflower, Taşkin Polat, Hakan Özer, Erdoğan Öztürk, Firat Sefaoğlu
Turkish Journal of Agriculture and Forestry
Non-oilseed sunflower plants can be exposed to lodging in some production regions due to higher plant height and larger heads, which is further exacerbated by heavily rainfall and strong winds. In this context, plant growth regulators such as mepiquat chloride (MC) can be considered as an alternative approach in reducing plant height and lodging. This study was conducted to determine the effect of MC application on the growth, yield, and yield components of non-oilseed sunflowers at different growth stages (V4, R1, R2, and R3) and rates (0, 30, 60, and 90 g a.i. ha-1) in Erzurum Province, eastern Anatolia, Turkey, …

Turkish Journal of Agriculture and Forestry
Downy mildew is a fungal disease caused by Plasmopara halstedii and leads to loss of yield up to 100% in sunflower. Disease control is performed mostly through chemical seed treatment and breeding. Due to the time consuming nature of conventional breeding, it is supported by biotechnological approaches. Marker-assisted selection (MAS) is a strategic approach in molecular breeding using molecular markers. Single nucleotide polymorphisms (SNPs) such as insertions, deletions, and base-pair substitutions are more advantageous than other molecular markers. The abundance and biallelic nature of SNPs in a genome provide flexibility in the choosing of SNPs at the desired loci. Competitive …

Bud Management Affects Fruit Wood, Growth, And Precocity Of Cherry Trees, İdri̇s Maci̇t, Gregory A. Lang, Hüsnü Demi̇rsoy
Turkish Journal of Agriculture and Forestry
As the production benefits of pruning fruit trees have been realized, growers have begun pruning periodically and, accordingly, various canopy training systems have begun to be developed. Following the genetic development of dwarfing rootstocks, interest has grown in the creation of modern training systems for smaller, more efficient orchards. During the formation of these training systems, it became apparent that branches of a certain size can alter the partitioning of growth resources (nutrients and carbohydrates) within the tree, delaying the formation of the target canopy structure as well as fruit bearing. In recent years, studies have focused on management of …

Cervical dystonia is a common neurological movement disorder characterised by muscle contractions causing abnormal movements and postures affecting the head and neck. The neural networks underpinning this condition are incompletely understood. While animal models suggest a role for the superior colliculus in its pathophysiology, this link has yet to be established in humans. The present experiment was designed to test the hypothesis that disrupted superior collicular processing is evident in affected patients and in relatives harbouring a disease-specific endophenotype (abnormal temporal discrimination). The study participants were 16 cervical dystonia patients, 16 unaffected first-degree relatives with abnormal temporal discrimination, 16 unaffected …

Developmental Immunity Of The Skeletal Elements Of The Weberian Apparatus To The Effects Of Exogenous Estrogen (17-Β Estradiol), A Known Disruptor Of Cartliage Development, Bailey Jordan Wetherell
Honors Program Theses
Proper vertebrate development is controlled by a tightly regulated sequence of gene activation and repression. Exposure to both endogenous (hormones, gene products) and exogenous (environmental chemicals, toxins, etc.) substances during development can have profound effects on morphology by altering growth, cell fate, cell differentiation, and cell migration. Waterways have long been hot-spots for chemical and toxin accumulation, due to runoff and waste dumping. Growing concern is being paid to endocrine disruptors, like estrogen (17β-estradiol), which are found in increasing levels in rivers and streams. Endocrine disruptors are known to cause a varied number of defects in fish species, but the …

Vitaceae is the grape family of flowering plants that is composed of twelve genera of woody plants (Jones et al., 2013). Vitis has been studied extensively for the commercial value of the fruit in the wine and grape production. However, not a lot of research has been done specifically on its basic biology such as leaf development within the family.
Understanding the basic biology of the plant can help with understanding its growth habit and help with improving the overall health of the plant. For example, analyzing flowers and leaves is a good way to draw inferences about developmental similarities …

The Effects Of Hibernation On The Time Of Coagulation Of The American Bullfrog, Rana Catesbeiana, Joshua Samec
Honors Program Theses
Cold conditions during winter months greatly reduce heart rate in ectothermic animals, such as bullfrogs, resulting in slow, intermittent blood flow. Slow or intermittent flow of blood often results in coagulation, yet the blood of these ectotherms fails to coagulate. In this study, the effects of the stages of hibernation from the onset of temperature decline, through the duration of constant low temperature exposure, was studied by observing the time of blood coagulation of American bullfrogs (Rana catesbeiana) using activated partial thromboplastin time (aPTT). It was found that the time of coagulation increased incrementally along with the decreasing …

Modeling Microorganism Transmission With Madagascar Hissing Cockroaches: An Inquiry Activity, Hillary Guzik, Kessler Mccoy-Simandle
Department of Entomology: Faculty Publications
Students will test Madagascar hissing cockroach’s capacity as a vector for transmission of microorganisms. By comparing a cockroach exposed to human contact (handled by students) and a cockroach with limited exposure (not handled), students can assess the ability of cockroaches to transmit microorganisms from one location (hands) to another (agar plate where the microorganism will be grown). This will allow students to determine if the Madagascar hissing cockroach, the classroom pet, is a potential vector for microorganisms. Students then will be able to question and relate the concept of insects and objects as vectors for common pathogen transfer.

Background: Aphid infestation of switchgrass (Panicum virgatum) has the potential to reduce yields and biomass quality. Although switchgrass-greenbug (Schizaphis graminum; GB) interactions have been studied at the whole plant level, little information is available on plant defense responses at the molecular level.
Results: The global transcriptomic response of switchgrass cv Summer to GB was monitored by RNA-Seq in infested and control (uninfested) plants harvested at 5, 10, and 15 days after infestation (DAI). Differentially expressed genes (DEGs) in infested plants were analyzed relative to control uninfested plants at each time point. DEGs in GB-infested plants induced …

Department of Entomology: Faculty Publications
The increased use of thiamethoxam seed treatments for controlling pests such as the bean leaf beetle, Cerotoma trifurcata (Forster) (Coleoptera: Chrysomelidae), suggests the need for methods to measure and monitor the development of resistance to thiamethoxam. The objectives of this study were to develop a bioassay method that can be used to monitor bean leaf beetle susceptibility to thiamethoxam, and to quantify the relative concentrations of thiamethoxam and clothianidin in early growth stage soybean tissue treated with thiamethoxam as a seed treatment. Overwintered and F1 bean leaf beetles were collected from alfalfa and soybean fields and used in excised soybean …

Soybean aphid, Aphis glycines (Hemiptera: Aphididae), is the most economically important soybean [Glycine max (L.) Merr.] pest of North America. Multiple studies have identified soybean expressing antibiosis and/or antixenosis; however, soybean tolerance remains underexplored. Tolerance to soybean aphid injury was previously identified in soybean KS4202. This research examined the yield response of KS4202 infested with soybean aphid at specific plant stages and identified at what plant stage tolerance initiates. A preliminary study evaluated the yield parameters of the tolerant genotype at low (4000– 5500 cumulative aphid-days [CAD]) and high aphid pressure (7500–8500 CAD) at different growth stages (V1, V3, …

Department of Entomology: Faculty Publications
Drosophila suzukii (Matsumura) is an invasive species that is a devastating pest of soft-skinned fruit crops. Although much effort has been directed toward developing traps and attractants to monitor for D. suzukii, current monitoring tools do not reliably predict fruit infestation. The objective of this study was to determine if D. suzukii females at different developmental stages are differentially attracted to monitoring traps with fermentation-based baits and ripe fruits. Females were collected on the surface of traps, within traps, and on ripe fruits during three experiments at field locations in North Carolina, USA, and were dissected to determine their reproductive …

Performance Of Seed Treatments And In-Furrow At-Plant Insecticides For Protection Against Cry3bb1-Resistant Western Corn Rootworm, 2015, Jonas Victor De Macedo,, Kayla A. Mollet, Julie A. Peterson
Department of Entomology: Faculty Publications
The western corn rootworm is an important pest of corn that can compromise yield by feeding on plant roots during its larval stage. WCRW management has been complicated by the development of resistance in some regions, including Nebraska, to transgenic Bacillus thuringiensis (Bt) traits, particularly the protein Cry3Bb1, which confers cross-resistance to mCry3A. A field trial was established to evaluate the efficacy of neonicotinoid seed treatments in combination with in-furrow insecticides on a corn hybrid expressing mCry3A Bt proteins against corn rootworm in an area with a history of rootworm resistance. The trial was conducted in a farmer’s field in …

Greater than expected injury by western corn rootworm (WCR) (Diabrotica virgifera virgifera LeConte) to Cry3Bb1 expressing maize hybrids (Zea mays L.) has been reported in southwestern Nebraska. Affected areas of some fields are often associated with high pH calcareous soils where maize growth is poor and iron chlorosis is common. As part of a comprehensive study to understand potential causes of unexpected injury, experiments were conducted during 2013 and 2014 to ascertain whether the calcareous soil conditions and associated poor maize growth negatively affect the expression of Cry3Bb1. Quantitative determination of Cry3Bb1 protein expression levels in root tissues …

Dry bulb mite (DBM), Aceria tulipae, is an economically important mite with a worldwide distribution and a broad host range. As a generalist, it is the most important eriophyoid mite attacking bulbous plants such as garlic, onion and tulip. To date, DBM has been recorded on host plants belonging to the families Liliaceae, Amaryllidaceae, Melanthiaceae and Asparagaceae. However, a precise understanding of DBM host range is lacking as it is largely based on casual records of mites on plants, some of which may include accidental hosts. Moreover, the possible existence of cryptic species has not been considered. In this …

The effect of the fungus Metarhizium anisopliae Ma14 strain, D-limonene, and cypermethrin, alone and combined, on the mortality of Rhipicephalus sanguineus Latreille larvae was evaluated. Eight separate groups with 25 tick larvae were inoculated with the fungus, cypermethrin, and D-limonene, and four groups were used as untreated controls. The groups were inoculated with serial dilutions of each treatment material: for example, conidial concentrations were 1 x 101, 1 x 102, 1 x 103, 1 x 104, 1 x 105, 1 x 106, 1 x 107, and …
The Effect Of The Chromoshadow Domains Of Hhp1, Hpl1, And Hpl2 On Heterochromatin Protein Localization In Tetrahymena Thermophila, Claire Bagnani
The Effect Of The Chromoshadow Domains Of Hhp1, Hpl1, And Hpl2 On Heterochromatin Protein Localization In Tetrahymena Thermophila, Claire Bagnani
Scripps Senior Theses
In the nucleus, post-translational modifications on histone N-terminal tails can determine how local DNA is packaged. In one case, T. thermophila proteins Hhp1, Hpl1, and Hpl2, all related to the Heterochromatin Protein 1 (HP1) family, are associated with heterochromatin and thus gene silencing. They may do this by binding to trimethylated lysine 9 and lysine 27, located on the tail of histone H3. One distinct region of these proteins, the chromodomain (CD), may bind these marks, while another region, the chromoshadow domain (CSD) homodimerizes to interact with other proteins. This study explores what effect, if any, the CSD has on …

Loop Current Spin-Off Eddies, Slope Currents And Dispersal Of Reef Fish Larvae From The Flower Gardens National Marine Sanctuary And The Florida Middle Grounds, Donald R. Johnson, Harriet Perry, Guillermo Sanchez-Rubio, Mark A. Grace
Gulf and Caribbean Research
Large energetic spin—off eddies from Loop Current intrusions into the Gulf of Mexico play a major role in water exchange between the continental shelf and the deep basin in the northern Gulf. Reef fish larvae, spawned on the outer shelf and planktonic during their early life history, are broadly dispersed by this mechanism, but may be lost to the cohort by transport away from suitable settlement habitat. In this study, satellite altimeter data—assimilative ocean model currents (HYCOM) from 2003—2015 are used to calculate kinetic energy of the mixed layer over the upper continental slope (200 m —1000 m) due to …

Polyphenols content and antioxidant activity in Artemisia sieversiana Willd. were investigated in relation to the altitude of the plant growth in the Western Pamir region. Antioxidant activity generally correlated with the polyphenols content. However, no significant association was found between an altitude of the sample collection and polyphenols content or antioxidant activity.
