Expression Analysis Of A Glucose Oxidase Transgene In Tobacco, Jordan Burt Jan 2015

Expression Analysis Of A Glucose Oxidase Transgene In Tobacco, Jordan Burt

Honors Theses

Glucose oxidase (GOX) is an enzyme in plants that catalyzes the oxidation of glucose to hydrogen peroxide and Glucono delta-lactone[5]. We have expressed GOX under the control of an estrogen inducible system, XVE, to analyze the gene's expression under this system compared to a system using the 35s system. The 35s system contains a promoter that constitutively turns on the GOX gene in the Nicotiana tabacum plant which causes the gene to always be turned on. Leaf disc assays were performed with discs from 35s, XVE, and also wild type plants (not containing the GOX gene) in order to extract …

Algae contribute to self-purification of streams and rivers and are necessary as food for fish and as components of aquatic food webs (1). However, too much or too little algae may create or be indicative of a problem. If nutrients are present in large amounts, algae growth may become excessive, resulting in algal “blooms.” These algal blooms can change the chemistry of the water, making it toxic to other aquatic occupants, including fish, birds, animals, and other plants (1). On the other hand, if nutrients in the water are limiting or are exhausted, algae growth is inhibited, which results in …
