Identification Of Key Genes Required For Abiotic Stress Response In Arabidopsis Thaliana, Saori Endo
Undergraduate Honors Capstone Projects
To identify key genes that are required for stress response, a reverse genetics approach was taken to manipulate expression of candidate genes in plants. In this project, two potential regulatory genes which were originally identified as stress-responsive genes from a microarray experiment in Arabidopsis were examined for their roles in stress tolerance. Over-expression of gene A, which was up-regulated under stress conditions based on the array data, caused earlier flowering and improved plant growth under salinity and dehydration stress conditions at the seedling stage. Over-expression of gene B, which was down-regulated under stress conditions based on the array data, resulted …

Obesity: Environment Vs. Genetics, Kammi Marie Reeder Hansen
Undergraduate Honors Capstone Projects
The prevalence of overweight and obese individuals is rising. Between 1980 and 1990 there was an 8% increase in the prevalence of obesity. Obesity is associated with many diseases such as hypertension, type 2 diabetes, heart disease and cancer. Over $39 billion dollars is spent annually on the illnesses associated with obesity. Our American culture has been blamed for the rise in obesity, yet there are obviously many people living in the American culture that are not obese. Researchers have turned to genetics to explain this phenomenon. This article will examine the many environmental factors that contribute to obesity and …
