Genomewide Evaluation Of Cis-Elements And Cognate Transcription Factors In Nicotiana Attenuata Predicts 27 Unique Transcription Factor-Binding Site Pairs, Ashton Omdahl
Undergraduate Honors Theses
Nicotiana attenuata has been widely studied for its ecological plant-herbivore relationships and response to environmental stress. The jasmonate signaling pathway regulated by jasmonate ZIM-domiain (JAZ) repressor proteins that modulate defense response levels has been of particular focus in this research. While our understanding of the genes associated with defense response and their regulation continues to expand, the transcriptional regulation of these genes is largely uncharacterized. In an effort to provide insight into these relationships, we performed genomewide analysis of transcript level data in order to predict transcription factors (TFs), their respective binding sites (TFBS), and the genes they regulate. We …
The Physiological Effects Of Exercise On California Yellowtail (Seriola Dorsalis) White Muscle, Julie Giannini
The Physiological Effects Of Exercise On California Yellowtail (Seriola Dorsalis) White Muscle, Julie Giannini
Undergraduate Honors Theses
California yellowtail (Seriola dorsalis) is a species of ray-finned fish that demonstrates a significant increase in muscle mass in response to sustained exercise at optimal swimming speed. In this study, three groups of yellowtail have been analyzed for a 6-month period to determine if the length of exercise affects white muscle fiber development and if these changes persist when the exercised fish have been returned to a normal “resting” condition. Gene analysis was performed to test if MyoD, a myogenic regulatory factor, was upregulated in response to exercise. To test these questions, the groups compared included a control …
Effect Of Adult Chemical Cues On Molting Of Fiddler Crab Megalopae In Low Salinity Seawater, Sydney Rilum
Effect Of Adult Chemical Cues On Molting Of Fiddler Crab Megalopae In Low Salinity Seawater, Sydney Rilum
Undergraduate Honors Theses
Three species of fiddler crabs, Uca minax, U. pugnax, and U. pugilator, are commonly found in estuaries along the Atlantic coast, each with distinct adult habitats differing in salinity and sediment grain size. Prior research has found evidence for larvae exhibiting selective settlement; however, the degree to which and the method by which they choose their species-appropriate habitat to settle in is still unknown. Additionally, a recent study determined that chemical cues from adult crabs stimulate molting in field-caught fiddler crab megalopae, as previously determined in lab-reared megalopae; however, in 35 ppt seawater, few U. minax molted. …
Social Play Predicts Docility In Juvenile Ground Squirrels, James Hurst-Hopf, Scott L. Nunes
Social Play Predicts Docility In Juvenile Ground Squirrels, James Hurst-Hopf, Scott L. Nunes
Undergraduate Honors Theses
We evaluated the hypothesis that social play behavior influences the development of temperament in young animals, using docility as a measure of temperament. We observed the play behavior of juvenile Belding’s ground squirrels (Urocitellus beldingi) during the developmental period in which play primarily occurs, and conducted behavioral tests measuring docility at the beginning and end of the play interval. Tests involved handling squirrels and recording their responses. Body mass was a reliable predictor of docility at the beginning of the play period. Rates of social play and maximum distances traveled from the natal burrow during the play interval …
