Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

The Effects of 2,3-butanediol on Arabidopsis and Various Crops

Climate change has the potential to reduce the amount of land that is suitable for crop growth. Such changes may cause food shortages, which would most likely disproportionately affect the poorest regions of the world. While GMO crops showed potential to increase crop yield and agricultural efficiency, significant public pushback has led to a search for alternative methods to generate similar results. Compounds produced by bacteria, such as 2,3-butanediol, offer a potential way to change the phenotypes of plants without the deliberate genomic changes involved in the development of GMOs which are often the subject of great controversy. These compounds influence how plants grow and function. Through precise application, the compounds could be used to improve crop yield and stress tolerance. While these effects are not completely understood, they may be due to changes in transcription and translation of certain proteins, the microbiome surrounding the plants and its interactions with the compounds, or other unknown factors. The compound 2,3-butanediol appears to increase biomass, lead to larger root systems and more root hairs, and increase germination rates in a variety of plants. All these traits are favorable for producing higher yields and enduring stress conditions. The phenotypes induced by this compound are similar to plants engineered to over express a type I proton pyrophosphatase. Plants treated with 2,3-butanediol offer a potential option to achieve the benefits of GMO crops without the attached social stigma.
