Abstract
[EMBARGOED UNTIL 12/01/2025] "In conclusion, the modern cultivated soybean (Glycine max) is a paleopolyploid dicot from South Asian ancestry. Domesticated in the United States in 1765 and originally used for fodder, the plant has continued to evolve from its ancestor and develop light colored seeds which are larger in size and heavier in oil content than its predecessor, Glycine soja. Soybeans became a popular crop during war-time as an oil and lubricant supply, before becoming a protein-rich feed source for livestock. The United States and Brazil are the top producers of this crop, and it is currently a multi-billion-dollar industry worldwide. Soybeans have become the focus of many scientific studies through public and private institutions. Studies of soybean may range from developing more agronomically productive lines, to determine disease resistance, uncovering genes, improving the composition of the seed itself, and/or developing transgenic lines via gene editing techniques. Of the many facets of soybean one could study, I have focused my efforts on determining the genetic architecture underlying a number of seed composition traits such as seed oil, protein, fatty acid, amino acid, or elemental components. My research has utilized genetically diverse germplasm panels and robust phenotypic measurements to develop high-powered studies which provide rough resolution of critical genetic architecture. My research is the first step in the eventual detection and determination of genes controlling traits of interest for further development opportunities such as trait introgression, gene edits, or other applications. This work will serve the scientific community as a whole and provide more information to the community about what is known regarding the soybean genome."--Pages 20-21.
