Development Of Est-Derived Simple Sequence Repeat (Ssr) Markers In Italian Ryegrass (Lolium Multiflorum Lam.), M. Hirata, Y. Miura, T. Takamizo, M. Fujimori

IGC Proceedings (1977-2023)

Italian ryegrass (IRG, Lolium multiflorum Lam.) is an important grass species used for agricultural purposes in Japan. Linkage maps in IRG have been constructed using molecular markers including RFLPs, AFLPs (Inoue et al., 2003) and genomic SSRs. The SSR marker is a useful tool for genome analysis because it is PCR-based with a relatively high level of polymorphism, co-dominantly expressed. The EST-SSR markers are expected to be more conserved and have a higher rate of transferability than genomic SSR markers (Scott et al., 2000), and the gene functions of ESTs may be predicted. Ikeda et al. (2004) …

Investigations Of The Effects Of Mutations In Inscuteable Mediated Pins-Mud Complex And Par Complex Functions In Drosophila Neuroblast, Ryan Liu

Research & Creative Achievement Day

Drosophila melanogaster central brain neuroblasts asymmetrically segregate proteins along the cell's apical-basal axil. Divisions along abnormal orientations or the complete failure to divide asymmetrically may result in overgrowth phenotypes. Neuroblastoma, one of the deadliest solid tumor diseases with extremely poor survival rate for late stages, is an example of this dysregulation. The protein Inscuteable (Insc) was previously found to bind with the protein Partner of Inscuteable (Pins; mPins or LGN in mammals), a receptor-independent G-protein activator, which is a subunit of the Pins-Gαi complex. The combined complex recruits Dlg to ensure correct spindle attachment on the cortex of the cell, …

Validation Of Computational Methods For The Tautomerism Of Thiourea Dioxide, Mckenna Lund

Research & Creative Achievement Day

In solution, thiourea dioxide exists in an equilibrium between its dioxide and sulfinic acid forms. This tautomeric relationship, as they all are, is substantially influenced by the solvent's polarity and hydrogen bonding capabilities. More well-known systems, e.g., acetylacetone, have been extensively studied in this regard, while thiourea dioxide's equilibrium has not. We have initiated a hybrid computational-spectroscopic investigation of this system utilizing low-cost Hartree-Fock methods with the 3–21G, 3–21+G, 3–21G*, 3–21+G*, MINI, MIDI, SBKJC and HW basis sets. Beyond gas phase calculations, both tautomeric forms were modeled using the C-PCM implicit solvent model for water and toluene. Obtained modeling results …

Improvement Of Native Perennial Forage Plants For Sustainability Of Mediterranean Farming Systems, F. Lelièvre, Florence Volaire

IGC Proceedings (1977-2023)

The amount of water available to agriculture in the Mediterranean is declining because of increasing population pressure and greater incidence of drought. Therefore, the efficiency of the use of water for agricultural production must be maximized and, in this context, perennial forage species have a number of advantages in comparison to the predominantly-used annuals. They can utilize water throughout the whole year besides being able to halt rangeland degradation, restore soil fertility and enhance forage production, thereby contributing to greater sustainability of rain-fed agricultural systems in the southern European Union and North Africa. Despite these advantages, the small size of …

The Potential For Summer-Dormant Perennial Grasses In Mediterranean And Semi-Arid Pastures, F. Lelièvre, Florence Volaire, P. Chapon, M. Norton

IGC Proceedings (1977-2023)

In rain-fed Mediterranean and semi-arid areas, herbage production of perennial grasses depends on their ability to grow efficiently during the rainy seasons and to persist over the dry summer. A key survival strategy in these harsh conditions is summer dormancy (Volaire, 2002). Within the species Dactylis glomerata L., two cultivars (cvs.), contrasting in this trait, were compared in order to analyse their suitability in terms of yield and survival in these environments.

Crown Rust Resistance In Transgenic Italian Ryegrass (L. Multiflorum) Expressing A Rice Chitinase Gene And Crosses With Cytoplasmic Male Sterile Hybrid Ryegrass, W. Takahashi, M. Fujimori, Y. Miura, T. Komatsu, S. Sugita, A. Arakawa, Y. Nishizawa, H. Sato, Y. Mano, T. Hibi, T. Takamizo

IGC Proceedings (1977-2023)

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grasses in the temperate region. In ryegrasses, crown rust (Puccinia coronata) is the most serious foliar fungal disease and brings about a reduction of herbage yield and loss of palatability to grass-eating domestic animals. In this study, we tried to increase tolerance to the pathogen by introducing a rice chitinase gene using particle bombardment.

Genetic And Molecular Characterization Of Temperate And Tropical Forage Maize Inbred Lines, B. Alarcón-Zúñiga, E. Valadez-Moctezuma, T. Cervantes-Martinez, T. Cervantes-Santana, M. Mendoza‐Rodriguez

IGC Proceedings (1977-2023)

Livestock feeding in the Central highland of Mexico is based on harvest, grazing and annual forage conservation, with forage maize being the most important silage crop (Alarcón, 1995). Even though forage maize is extensively bred in Europe, USA and Asia since the 1900’s, this started in Mexico only in the 1960’s, and little is known about genetic diversity in both agronomic and nutritive value traits. Our breeding program goals are to analyze combining ability of biomass and quality predictors and to study the genetic relationship of inbred lines between lowland tropical and temperate races from Mesa Central, by genetic and …

The Use Of Molecular Markers In Genetic Variability Analysis Of A Collection Of Dactylis Glomerata L., R. Costa, G. Pereira, C. Vicente, M. M. Tavares De Sousa

IGC Proceedings (1977-2023)

Dactylis glomerata L. is one of the three most used perennial grasses in Europe (jointly with Lolium perenne and Festuca arundinacea). The main qualities of Dactylis glomerata are high productivity in pure cultures, high level of proteins and tolerance to drought, cold and shade (Mousset & Chosson, 1986). In the last ten years, techniques that allow direct discrimination at the DNA level have encouraged the study of the genetic variability within cultivated populations as well as identification of the diversity available in germplasm banks. DNA polymorphisms have been shown to be efficient in the identification of genetic variability in …

A core collection is a sub-set encompassing more than 70% of the variability of all accessions held in a collection (Brown, 1995). The development of one for Trifolium spumosum (bladder clover) could assist in future development of the cultivar within southern Australia. The aim of this work is to develop a core collection of Trifolium spumosum as a model for other pasture legume species using molecular and ecogeographical data.

Applying Bioactive Glass Beads For Long-Term Drug Delivery, Marie O. Sykes, Rashi Sharma

Physics and Astronomy Presentations

Bioactive glass beads have been used to distribute medicine over extended periods of time in limited uses. They can be engineered to have a porous and hollow structure, and using Mo-Sci's OL-GL 1756b (1756b), the fundamental notion of dosage distribution can be tested in preparation to design the optimal glass for medicine distribution. A few key factors in this is how long does it take the liquid to release from the beads, how do the beads decay, and how well the glass can bond to human tissue. This research demonstrates the capacities of the 1756b type as a promising start …

Nviz: Unraveling Neural Networks Through Visualization, Kevin Hoffman

Mathematics, Computer Science & Statistics Presentations

The growing utility of artificial intelligence (AI) is attributed to the development of neural networks. These networks are a class of models that make predictions based on previously observed data. While the inferential power of neural networks is great, the ability to explain their results is difficult because the underlying model is automatically generated. The AI community commonly refers to neural networks as black boxes because the patterns they learn from the data are not easily understood. This project aims to improve the visibility of patterns that neural networks identify in data. Through an interactive web application, NVIZ affords the …

"In The Beginning, God Created Atoms", Samiya L. Henry

Undergraduate Research and Scholarship Symposium

Genesis 1:1 states “In the beginning, God created the heavens and the earth.” This is the defining statement in the Bible and acts as the foundation of creation and God’s power in the Christian faith. On the other hand, many scientists believe the Big Bang Theory and the discoveries made in other fields of science solely define the creation of the universe and explain life as we know it, also disproving the Christian creation story and the overall existence of God. However, the exact opposite is true; God is science.

Alone, neither of these concepts (faith and science) fully solve …

Loss Scaling And Step Size In Deep Learning Optimizatio, Nora Alosily

Dissertations

Deep learning training consumes ever-increasing time and resources, and that is
due to the complexity of the model, the number of updates taken to reach good
results, and both the amount and dimensionality of the data. In this dissertation,
we will focus on making the process of training more efficient by focusing on the
step size to reduce the number of computations for parameters in each update.
We achieved our objective in two new ways: we use loss scaling as a proxy for
the learning rate, and we use learnable layer-wise optimizers. Although our work
is perhaps not the first …

A Large-Scale Survey Of Brown Dwarf Atmospheres, Savanah Kay Turner

Theses and Dissertations

Brown dwarfs are substellar objects that fall in-between the smallest stars and largest planets in size and temperature. Due to their relatively cool temperatures, the atmospheres of these 'failed stars' have been shown to exhibit interesting properties such as iron, silicate, and salt clouds. Theoretical atmospheric models based on known physics and chemistry can be used as tools to interpret and understand our observations of brown dwarfs. I have fit archival and new infrared spectra of over 300 brown dwarfs with atmospheric models. Using the parameters of the best-fit models as estimates for the physical properties of the brown dwarfs …

Synthetic, Catalytic, And Mechanistic Studies Of Supermesityl Phosphiranes And Phosphines, Ryan M. Tipker

Dartmouth College Ph.D Dissertations

Methylation of P-stereogenic phosphiranes Mes*PCH2CH(R) (Mes* = 2,4,6-(t-Bu)3C6H2, R = Me, Ph) with MeOTf gave P-stereogenic phosphiranium cations; [Mes*P(Me)CH2CH(Ph)][OTf] underwent syn-anti isomerization via P-epimerization. Mechanistic studies suggested ring opening gave a hyperconjugation-stabilized carbocation in which pyramidal inversion at P was promoted by s-interaction with the pendant cation. Attempted phosphirane protonation with HOTf resulted in ring opening and C-H activation of an o-t-Bu group to give phospholanium cations. Treatment of [Mes*P(Me)CH2CH(Ph)][OTf] with LiPPh2 gave bis(phosphino)ethanes. Copper- catalyzed P-alkylation of the secondary phosphine PHPh(Mes*) with benzyl bromides gave P-stereogenic tertiary phosphines with a supermesityl substituent.
