Evaluating Differences In The Dynamic Growth Patterns Of Cvi And Ler Genetic Strains Of Arabidopsis During Seedling Establishment, Emily Frost
Undergraduate Research Symposium (2026- )
Seedling establishment is the process by which seedlings transition from depending on seed nutrients to making their own through photosynthesis. An important aspect is photomorphogenesis, the growth of plants in response to light, transitioning from rapid embryonic stem growth to a slower rate focused on root growth and leaf formation. The process is influenced by many genetic and environmental factors, making better characterization essential to understand plant development. For our research, we examined the dynamic growth of two Arabidopsis genetic strains (Cvi and Ler) over time in response to darkness, then to the change in response when light is introduced. …

Investigating The Effects Of Gibberellin Treatments On Different Dwarf Millet Genotypes And Identifying The Mechanism Responsible For Genetic Dwarfism, Macie Mccarty, Audrie Miller, Quinn Calvert, Abi Waters, Dania Creary, Justin Coleman
2025 Student Academic Showcase
Gibberellins (GAs) are essential plant hormones involved in regulating growth and development, particularly in stem elongation, seed germination, and flowering. In cereal crops like millet, dwarf genotypes are of agricultural interest due to their potential for increased stability and yield efficiency. However, the genetic mechanisms underlying dwarfism in millet remain unclear. This study investigates the response of various dwarf millet genotypes to gibberellin treatments and seeks to determine the genetic basis of their dwarfism. We hypothesize that genotypes with gibberellin biosynthesis deficiencies will exhibit increased stem elongation when treated with gibberellin, while genotypes with signal transduction defects will show minimal …

2025 Student Academic Showcase
Dwarf and semidwarf variants of agricultural plants are used to decrease lodging without decreasing crop yield. Some dwarf genotypes lack the ability to produce the growth hormone gibberellin, and others lack complete receptor pathways. Exogenous gibberellic acid (GA) was applied to four dwarf millet genotypes over the course of six weeks to determine what pathway for dwarfism each dwarf genotype was. Statistical analysis was done to analyze the relationship between GA applications and increased plant growth. It was found that all genotypes had some response to the treatment, though some were more extreme than others. Additionally, the treatment group had …

Genetic Diversity In Helianthus Annuus: Selective Breeding And Induced Mutagenesis, Dillon Holton
Thinking Matters Symposium
H. annuus, more commonly known as the sunflower, is a single species that has many different variations. Traits have been selectively bred for hundreds of years in order to produce a beautiful flower as well as essential agricultural products. Recently interest in the sunflower as a food and fuel crop has led to selective breeding of seeds that produce high yields of sunflower oil. To further push the limits of this plant's genome, researchers have used mutagenesis to force mutations in hopes of developing novel modifications that could increase yield. With the entire genome mapped, the goal for many research …

Sustainability Of Genetically Modified (Gm) Crops, Abdul Hakeem, Wajid Ali Shah
CBER Conference
This proposal identifies the methods used in the modification of crops, their production, modification, expansion, benefits, and carbon emission. Moreover, the special focus of this proposal is to explain the need for GM crops for developing nations which are witnessing exponential growth of their populations. Additionally, it pursues to determine how in the environmental and economic context, the significance of GM crops is overwhelming and cannot be overlooked. The greenhouse ePect reduction is the other essential output of the GM crops as shown through the illustrations.

Expression Of Carbohydrates Biosynthetic Genes In Developing Soybean Seeds, Jayden Rosen, Karen A. Hudson
The Summer Undergraduate Research Fellowship (SURF) Symposium
An essential part of livestock diets is soybean meal, which is a major source of protein, but which also consists of antinutritional carbohydrates. Antinutritional carbohydrates such as raffinose and stachyose lead to irritation to the gut for monogastric livestock as well as unhealthy weight gain. A major objective of soybean genetics is to reduce these antinutritional carbohydrates within the seed and increase the levels of good carbohydrates. This will lead to healthier livestock and better meat quality. To select genes potentially responsible for variation in carbohydrate levels in seeds, the expression of genes encoding several biosynthetic enzymes was measured during …
Dawn Or Doom: The Risks And Rewards Of Emerging Technologies, Diana Hancock, Steve Tally, Gerry Mccartney, Michele Arthur
Dawn Or Doom: The Risks And Rewards Of Emerging Technologies, Diana Hancock, Steve Tally, Gerry Mccartney, Michele Arthur
Purdue P-12 Networking Summit & Poster Session
Dawn or Doom is a free and open to the public conference at Purdue where we focus on benefits and risks surrounding some of the technologies that are both the most disruptive to current practices and being adopted the fastest. A collection of Purdue faculty experts and some outside speakers showcase their many perspectives related to this technology explosion, explore conditions that will foster innovation and investment into the next generation, and address the big-picture issues where both optimism and pessimism are warranted.
Influence Of Ultraviolet Radiation On Cell Wall Constituents In Reduced-Lignin Mutants Of Corn And Sorghum, Brock Bermel
Influence Of Ultraviolet Radiation On Cell Wall Constituents In Reduced-Lignin Mutants Of Corn And Sorghum, Brock Bermel
Undergraduate Research Symposium
Brown midrib mutants (BMR) of corn (Zea mays) and sorghum (Sorghum bicolor) have reduced lignin content and have recently gained popularity in Southern Minnesota as forage material for grazing animals. These mutants have lowered expression of cinnamyl alcohol dehydrogenase and caffeic O-methyltransferase enzymes in the phenylpropanoid pathway responsible for the construction of the cinnamyl alcohol subunits of lignin. Lignin is found in the secondary cell wall of higher plants, along with substantial amounts of cellulose and hemicellulose polysaccharides. Reduced lignin increases livestock digestibility of these plants, but may also increase susceptibility to environmental stress and lodging. …

The Role Of A Transcription Factor In Regulating Rice Response To Drought Stress, Diana Ha, Liyuan A. Zhang, Jeffery Shen
Undergraduate Research Opportunities Program (UROP)
The current water shortage is a major concern in regard to our global climate change crisis. A decrease in the availability of water will have direct effects on the development of plants. Some crops, such as Oryza sativa, or commonly known as rice, requires an abundant amount of water for adequate growth. With the water shortage crisis, it will become extremely difficult to harvest such crops to meet the world’s food demand. However, many plants have evolved mechanisms for overcoming and tolerating stresses such as drought. My research focuses on studying the proteins involved with these mechanisms. The WRKY superfamily …

Oral Presentation: Plant Genes And Drought Tolerance, Norris Lam
Festival of Communities: UG Symposium (Posters)
Research has shown that a gene from C3 xerophyte Larrea tridentata (creosote bush), LtWRKY21, is involved in pathways governing creosote bush’s high tolerance to environmental stress. By understanding the way in which creosote bush adapts to drought, crop plants can be engineered to be more drought tolerant during times of imminent global climate change. To study the underlying mechanisms of creosote bush drought response, the LtWRKY21 gene was mobilized into the model organism Arabidopsis thaliana. Chlorophyll degradation, cellular electrolyte leakage, and water content in leaves will serve as indicators of drought tolerance in LtWRKY21-transgenic A. thaliana after treatment in chemically …
